PROXY STATEMENT
FOR 2001 ANNUAL MEETING OF SHAREHOLDERS
------------

PROCEDURAL MATTERS

General Information

This Proxy Statement is furnished to the shareholders of Cylink
Corporation, a California corporation ("us", "we" or the "Company"), in
connection with the solicitation by the Board of Directors of the Company (the
"Board" or "Board of Directors") of proxies in the accompanying form for use in
voting at the 2001 Annual Meeting of Shareholders of the Company (the "Annual
Meeting") to be held on May 16, 2001, at the Biltmore Hotel, 2151 Laurelwood
Road, Santa Clara, CA 95054, at 2:00 p.m., local time, and any adjournment or
postponement thereof. The shares represented by the proxies received, properly
marked, dated, executed and not revoked will be voted at the Annual Meeting.
The Company's headquarters are located at 3131 Jay Street, Santa Clara,
California 95056-0952.

Quorum And Voting Procedures

The close of business on March 30, 2001 has been fixed as the record date
(the "Record Date") for determining the holders of shares of common stock of
the Company (the "Common Stock") entitled to notice of and to vote at the
Annual Meeting. As of the close of business on the Record Date, the Company had
32,706,298 shares of Common Stock outstanding and entitled to vote at the
Annual Meeting. The presence at the Annual Meeting of a majority of these
shares of Common Stock of the Company, either in person or by proxy, will
constitute a quorum for the transaction of business at the Annual Meeting.

In the election of directors, the two candidates receiving the highest
number of affirmative votes will be elected as directors. Any other proposals
require for approval (i) the affirmative vote of a majority of the shares
"represented and voting" and (ii) the affirmative vote of a majority of the
required quorum. The required quorum for the transaction of business at the
Annual meeting is a majority of the shares of Common Stock issued and
outstanding on the Record Date (the "Quorum"). Shares that are voted "FOR",
"AGAINST" or "ABSTAIN" in a matter are treated as being present at the meeting
for purposes of establishing the Quorum, but only shares voted "FOR" or
"AGAINST" are treated as shares "represented and voting" at the Annual Meeting
(the "Votes Cast") with respect to such matter. Accordingly, abstentions and
broker non-votes, if any, will be counted for purposes of determining the
presence or absence of the Quorum for the transaction of business, but will not
be counted for purposes of determining the number of Votes Cast with respect to
a proposal.

Revocability Of Proxies

Any proxy given pursuant to the solicitation may be revoked by the person
giving it at any time before it is voted. Proxies may be revoked by (i) filing
with the General Counsel of the Company at or before the taking of the vote at
the Annual Meeting a written notice of revocation bearing a later date than the
proxy, (ii) duly executing a later dated proxy relating to the same shares and
delivering it to the General Counsel of the Company at or before the taking of
the vote at the Annual Meeting or (iii) attending the Annual Meeting and voting
in person (although attendance at the Annual Meeting will

not in and of itself constitute a revocation of a proxy). Any written notice of
revocation or subsequent proxy should be delivered to Cylink Corporation, P.O.
Box 54952, 3131 Jay Street, Santa Clara, California 95056-0952, Attention:
General Counsel, or hand-delivered to the General Counsel of the Company at or
before the taking of the vote at the Annual Meeting.

Solicitation Of Proxies

The solicitation of proxies will be conducted by mail and the Company will
bear all attendant costs. These costs will include the expense of preparing and
mailing proxy materials for the Annual Meeting and reimbursements paid to
brokerage firms and others for their expenses incurred in forwarding
solicitation material regarding the Annual Meeting to beneficial owners of the
Company's Common Stock. The Company may conduct further solicitation
personally, by telephone or by facsimile through its officers, directors and
regular employees, none of whom will receive additional compensation for
assisting with the solicitation.

Shareholder Proposals

To be considered for presentation to the annual meeting of shareholders to
be held in the year 2002, a shareholder proposal must be received by the
General Counsel of Cylink Corporation, P.O. Box 54952, 3131 Jay Street, Santa
Clara, California 95056-0952, no later than December 14, 2001. In addition, a
shareholder who intends to present a proposal at the Company's annual meeting
of shareholders in the year 2002 without inclusion of the proposal in the
Company's proxy materials may wish to provide written notice of such proposal
to the Company's General Counsel no later than ninety days prior to such
meeting. If the shareholder proponent does not do so, management may use its
discretionary voting authority to vote on such proposal for all of the shares
for which executed proxies are received. Further, the Company reserves the
right to reject, rule out of order, or take other appropriate action with
respect to any proposal that does not comply with the foregoing requirements
and other requirements of the proxy rules promulgated by the Securities and
Exchange Commission. In order to avoid any dispute as to the date on which a
proposal was received by the Company, it is suggested that proponents submit
their proposals by certified mail, return receipt requested.

PROPOSAL NO. 1

ELECTION OF DIRECTORS

As set by the Board of Directors pursuant to the Bylaws of the Company,
the authorized number of directors is set at eight. Two directors will be
elected at the Annual Meeting to serve as Class 3 directors until the 2004
Annual Meeting of Shareholders or until their successors are elected or
appointed and qualified or until the director's earlier resignation or removal.
In the event that any nominee of the Company is unable or declines to serve as
a director at the time of the Annual Meeting, the proxies will be voted for any
nominee who shall be designated by the present Board of Directors to fill the
vacancy. In the event that additional persons are nominated for election as
directors, the proxy holders intend to vote all proxies received by them in
such a manner as will ensure the election of as many of the nominees listed
below as possible, and, in such event, the specific nominees to be voted for
will be determined by the proxy holders. The Board has no reason to believe
that the persons named below will be unable or unwilling to serve as a
director, if elected. Each of the two nominees for director who receives the
greatest number of votes will be elected.

Employment Agreements

We entered into an employment agreement with Mr. Crowell in December 1997,
which agreement was amended in November 1998 (the "Crowell Agreement"). Under
the terms of the Crowell Agreement, Mr. Crowell is to be employed by the
Company until December 31, 2004 for an annual salary of $300,000 and is
eligible for an annual performance bonus of $100,000. Pursuant to the terms of
the Crowell Agreement, we made a loan to Mr. Crowell in the amount of
approximately $1,112,000 (the "Loan") to purchase a primary residence in
California commensurate with his prior residence in Maryland. The Loan will be
interest free for the period of his employment and secured by a deed of trust
on Mr. Crowell's principal residence. As of December 31, 2000, the total amount
outstanding under the Cromwell Loan was $1,112,000. Under the Crowell
Agreement, Mr. Crowell received a grant of options covering 350,000 shares of
our Common Stock, which options vest over a period of five years from the date
of his employment, a second grant of 500,000 options with 20% vesting upon the
grant in December 1998, and

the balance vesting ratably over four years, and a third grant of 150,000
options in January 1999, which options vest ratably over four years. These
options are subject to accelerated vesting, in certain circumstances, if there
is a change in control of Cylink.

In November 1998, our subsidiary, Algorithmic Research, Ltd., amended its
1996 employment agreement with Mr. Yosef A. Cohen (the "Cohen Agreement") under
which Mr. Cohen agreed to be employed as Algorithmic Research, Ltd.'s Chief
Executive Officer until December 31, 1999 at a salary of $250,000 per year and
a potential performance bonus of $50,000 per year. Under the Cohen Agreement,
Mr. Cohen received a grant of options covering 50,000 shares of our Common
Stock, which options were repriced in December 1998 and were to continue to
vest over the following three year period beginning December 1998. Mr. Cohen
received a second option grant covering 200,000 shares of our Common Stock in
November 1998, 20% of which vested immediately, with the balance vesting
ratably over four years from the date of grant. Mr. Cohen resigned as Chief
Executive Officer of Algorithmic Research Ltd., effective November 30, 2000.
Pursuant to the Cohen Agreement, Mr. Cohen received $195,000 as a severance
payment. At the time of his resignation, 113,462 of Mr. Cohen's options had
vested, all of which have since expired.

In October 1998, the Company entered into an employment agreement with Mr.
Barnes, which agreement was amended in August 1999 (the "Barnes Agreement").
Under the terms of the Barnes Agreement, Mr. Barnes was to be employed until
December 31, 2003 for an annual salary initially set at $200,000 and is
eligible for an annual performance bonus of $75,000. Under the terms of the
Barnes Agreement, Mr. Barnes received a grant of options covering 300,000
shares of our Company's Common Stock which options were to vest over a period
of five years from October 1998, subject to accelerated vesting, in certain
circumstances, if there is a change in control of Cylink. Pursuant to the terms
of the Barnes Agreement, we made a loan to Mr. Barnes in the amount of
approximately $565,000 (the "Loan") to purchase a primary residence in
California commensurate with his prior residence in Colorado. The Loan was
interest-free for the period of his employment and secured by a deed of trust
on Mr. Barnes' principal residence. Mr. Barnes resigned voluntarily as Vice
President, Finance and Chief Executive Officer effective November 17, 2000. In
accordance with the Barnes Agreement, interest accrues on the Loan at the rate
of not less than 7% and as of December 31, 2000, the full amount was
outstanding under the Loan. The Loan was due and payable on February 15, 2001
and has not yet been paid by Mr. Barnes. Mr. Barnes has 120,000 vested options,
which will all expire on April 1, 2001.

In January 1997, we entered into an employment agreement with Mr. Slocum
(the "Slocum Agreement"). Under the terms of the Slocum Agreement, Mr. Slocum
is to be employed until January 2002 for an annual salary initially set at
$185,000 and is eligible for an annual performance bonus of $70,000. Under the
Slocum Agreement, Mr. Slocum received a grant of options covering 250,000
shares of our Common Stock, which options now vest over a period of three years
from December 1998. These options are, in certain circumstances, subject to
accelerated vesting if there is a change of control of Cylink.

The Company entered into an executive retention agreement with Mr. Fougner
in June 1998 (the "Fougner Agreement"). The Fougner Agreement does not
guarantee any specific employment, salary or bonus, but does cover benefits Mr.
Fougner is entitled to upon the occurrence of certain events; including
involuntary termination upon a change in control of Cylink.

In November 2000, we entered into an employment agreement with Mr.
Chillingworth (the "Chillingworth Agreement"). Under the terms of the
Chillingworth Agreement, Mr. Chillingworth agreed to serve as Acting Chief
Financial Officer until February 2001 for an annual salary of $175,000, with
eligibility for an annual employment bonus of $75,000. Mr. Chillingworth
received a grant of options covering 100,000 shares of Cylink, with the first
25% of the options vesting immediately and the balance vesting monthly over a
four year period. These options are, in certain circumstances, subject to
accelerated vesting upon a change in control of Cylink. Mr. Chillingworth has
since become Chief Financial Officer and he and the Company are negotiating a
definitive employment agreement.

Certain Transactions

In 1997, we issued a $1,000,000 interest-free loan to Ms. Engel, our
former Vice President, Professional Services (the "Engel Loan"). Ms. Engel
resigned as the Company's Vice-President, Professional

Services, on August 21, 2000. The Engel Loan was interest-free during the
period of Ms. Engel's employment with us, and is due in March 2002. The Engel
Loan is secured by a deed of trust on Ms. Engel's principal residence. Pursuant
to the terms of a severance agreement entered into by and between the Company
and Ms. Engel, the Engel Loan is due on the earlier of the sale of Ms. Engel's
principal residence and February 2002. However, any profit Ms. Engel makes as a
result of exercises of certain options will be paid to Cylink and applied
against the loan balance. As of December 31, 1999, the total amount outstanding
was approximately $1,000,000.

REPORT OF THE COMPENSATION COMMITTEE
OF THE BOARD OF DIRECTORS

This section is not "soliciting material," is not deemed "filed" with the
Commission and is not incorporated by reference in any filing of the Company
under the Securities Act of 1933, as amended, or the Securities Exchange Act of
1934, as amended, whether made before or after the date hereof and irrespective
of any general language to the contrary.

The Compensation Committee of the Board was formed in December 1995 and
consists of Dr. Leo Guthart and Dr. James Simons. Decisions concerning the
compensation of our Chief Executive Officer is made by the Compensation
Committee and reviewed periodically by the full Board (excluding any interested
director). Decisions concerning the compensation of our executive officers are
made by the Chief Executive Officer in consultation with members of the
Compensation Committee. Policies concerning the terms of the 1994 Plan are
determined by the Compensation Committee and administered by certain of our
executive officers.

Executive Officer Compensation Programs

The objectives of the executive officer compensation programs are to
attract, retain, motivate and reward key personnel who possess the necessary
leadership and management skills, through competitive base salary, annual cash
bonus incentives, long-term incentive compensation in the form of stock
options, and various benefits, including medical and life insurance plans.

The executive compensation policies of the Compensation Committee are
intended to combine competitive levels of compensation and rewards for above
average performance and to align relative compensation with the achievements of
key business objectives, optimal satisfaction of customers, and maximization of
shareholder value. The Compensation Committee believes that stock ownership by
management is beneficial in aligning management and shareholder interests,
thereby enhancing shareholder value.

Base Salaries. Salaries for our executive officers are determined
primarily on the basis of the executive officer's responsibility, general
salary practices of peer companies and the officer's individual qualifications
and experience. Among other sources of information, the Compensation Committee
and the Chief Executive Officer rely on reports from Radford Associates
concerning competitive compensation practices in the Company's geographical
region. The base salaries are reviewed annually and may be adjusted in
accordance with certain criteria which include individual performance, the
functions performed by the executive officer, the scope of the executive
officer's on-going duties, general changes in the compensation peer group in
which the Company competes for executive talent, and our financial performance
generally. The weight given each such factor may vary from individual to
individual. Based on prior surveys, the base salaries for our executive
officers were at the approximate median of the base salary range for other
executive officers in comparable positions at comparable companies in our
industry and geographical region.

Incentive Bonuses. The Compensation Committee and the Chief Executive
Officer believe that a cash incentive bonus plan can serve to motivate our
executive officers and management to address annual performance goals, using
more immediate measures for performance than those reflected in the
appreciation in value of stock options. The bonus amounts are based upon a
subjective consideration of factors including such officer's level of
responsibility, individual performance, contributions to our success and to our
financial performance generally.

Stock Option Grants. Stock options are granted to executive officers and
other employees under the 1994 Plan. Because of the direct relationship between
the value of an option and the stock price, the Compensation Committee believes
that options motivate executive officers to manage the Company in a manner that
is consistent with shareholder interests. Stock option grants are intended to
focus the attention of the recipient on our long-term performance, which we
believe results in improved shareholder value, and to retain the services of
the executive officers in a competitive job market by providing significant
long-term earning potential. To this end, stock options generally vest over a
four-year period. However, the Compensation Committee continues to evaluate and
consider revisions to the various terms and conditions of our option
agreements, specifically with respect to the duration of the option agreements,
and the basis for issuing and vesting of awards. The principal factors
considered in granting stock options to our executive officers are prior
performance, level of responsibility, other compensation and the executive
officer's ability to influence our long-term growth and profitability. However,
the 1994 Plan does not provide any quantitative method for weighting these
factors, and a decision to grant an award is primarily based upon a subjective
evaluation of the past as well as future anticipated performance.

Deductibility of Compensation. Section 162(m) of the Internal Revenue Code
(the "IRC") disallows a deduction by us for certain compensation exceeding $1
million paid to any named executive officer, excluding, among other things,
certain performance based compensation. Because the compensation figures for
the Named Executive Officers have not approached the limitation, the
Compensation Committee has not had to use any of the available exemptions from
the deduction limit. However, the 1994 Plan is designed to qualify any
compensation realized by Named Executive Officers from the exercise of an
option as performance based compensation. The Compensation Committee remains
aware of the existence of the IRC Section 162(m) limitations, and the available
exemptions, and will address the issue of deductibility when and if
circumstances warrant the use of such exemptions in addition to the exemption
contemplated under the 1994 Plan.

Chief Executive Officer Compensation

The compensation of the Chief Executive Officer is reviewed annually on
the same basis as discussed above for all executive officers. Mr. Crowell's
base salary for the fiscal year ended December 31, 2000 was $300,000. Although
Mr. Crowell is eligible for an annual minimum bonus of $150,000 most of the
Company's executive officers, including Mr. Crowell, agreed to forgo bonuses
for services performed during 2000. Mr. Crowell's base salary was established
in part by comparing the base salaries of chief executive officers at other
companies of similar size, the compensation for our previous Chief Executive,
and past proposals by competing candidates for the position of Chief Executive
Officer. Based on prior surveys, the base salary offered to Mr. Crowell was at
the approximate median of the base salary range for other Chief Executive
Officers of comparable companies in our industry and geographical region.

REPORT OF THE AUDIT COMMITTEE
OF THE BOARD OF DIRECTORS

The Audit Committee of the Board was formed in 1995 and consists of Dr.
Howard L. Morgan, Dr. William W. Harris, Dr. Elwyn Berlekamp and Mr. Paul
Gauvreau, directors who meet the independence and experience requirements of
the National Association of Securities Dealers. The Audit Committee oversees a
comprehensive system of internal controls to ensure the integrity of the
financial reports and compliance with laws, regulations, and corporate
policies, and recommends resolutions for any dispute that may arise between
management and the Company's auditors.

Consistent with this oversight responsibility, the Audit Committee has
reviewed and discussed with management the audited financial statements for the
year ended December 31, 2000. Deloitte & Touche LLP, the Company's independent
auditors, issued their unqualified report dated as of February 6, 2001 on the
Company's financial statements.

The Audit Committee has also discussed with Deloitte & Touche LLP the
matters required to be discussed by AICPA Statement on Auditing Standards No.
61, "Communication with Audit Committees". The Audit committee has also
received the written disclosures and the letter from Deloitte & Touche LLP
required by Independence Standards Board Standard No. 1, "Independence
Discussions with Audit Committees," and has conducted a discussion with
Deloitte & Touche LLP relative to its independence, including whether Deloitte
& Touche LLP's provision of non-audit services is compatible with its
independence. A copy of the Audit Committee Charter is attached as Appendix A.

Based on these reviews and discussions, the Audit Committee recommended to
the Board of Directors that the Company's audited financial statements for the
year ended December 31, 2000 be included in the Annual Report on Form 10-K for
the fiscal year then ended.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

Our Compensation Committee currently consists of Dr. Leo A. Guthart and
Dr. James H. Simons. No interlocking relationship exists between any member of
our Board of Directors or Compensation Committee and any member of the board of
directors or compensation committee of any other company, nor has any such
interlocking relationship existed in the past. No member of the Compensation
Committee is or was formerly an officer or an employee of the Company or its
subsidiaries.

STOCK PERFORMANCE GRAPH

The following graph compares the percentage change in the cumulative total
shareholder return on our Common Stock from February 15, 1996, the date of our
initial public offering, through the end of our fiscal year ended December 31,
2000, with the percentage change in the cumulative total return for the Nasdaq
Composite Index and the Hambrecht & Quist Technology Index. The comparison
assumes an investment of $100 on February 15, 1996 in our Common Stock and in
each of the foregoing indices and assumes reinvestment of dividends. The stock
performance shown on the graph below is not necessarily indicative of future
price performance.

CHANGES IN INDEPENDENT PUBLIC ACCOUNTANTS

Previous Independent Accountants

On July 12, 1999, we dismissed PricewaterhouseCoopers LLP, which had
previously served as our independent accountants, and engaged Deloitte & Touche
LLP as our new independent accountants.

The reports of PricewaterhouseCoopers LLP on the financial statements for
our past two fiscal years contained no adverse opinion or disclaimer of opinion
and were not qualified or modified as to uncertainty, audit scope or accounting
principle.

The Audit Committee of the Board of Directors participated in and approved
the decision to change independent accountants.

In connection with its audits for the two most recent fiscal years and
through July 12, 1999, there were no disagreements with PricewaterhouseCoopers
LLP on any matter of accounting principles or practices, financial statement
disclosure, or auditing scope or procedure, which disagreements, if not
resolved to the satisfaction of PricewaterhouseCoopers LLP, would have caused
PricewaterhouseCoopers LLP to make reference thereto in their report on the
financial statements for such years.

During the two most recent fiscal years and through July 12, 1999, there
were no reportable events as that term is defined in Item 304(a)(1)(v) of
Regulation S-K.

We requested that PricewaterhouseCoopers LLP furnish us with a letter
addressed to the Commission stating whether or not it agrees with the above
statements. A copy of such letter, dated July 19, 1999, is filed as Exhibit
16.1 to our Form 8-K, filed with the Securities and Exchange Commission on July
19, 1999.

New Independent Accountants

As stated above, we engaged Deloitte & Touche LLP as our new independent
accountants as of July 12, 1999. The Audit Committee of the Board of Directors
approved such engagement on June 21, 1999.

In October, 1998, Wilson Sonsini Goodrich & Rosati, outside counsel to
Cylink, retained Deloitte & Touche LLP to assist Wilson Sonsini Goodrich &
Rosati in a review of our prior revenue recognition practices. In conjunction
with that engagement, Deloitte & Touche LLP provided oral and written advice to
assist Wilson Sonsini Goodrich & Rosati and the Audit Committee regarding
matters relating to such revenue recognition practices.

During the two most recent fiscal years and through July 12, 1999, we did
not consult with Deloitte & Touche LLP on any matter that was either the
subject of a disagreement, as that term is defined in Item 304(a)(1)(iv) of
Regulation S-K and the related instructions to Item 304 of the Regulation S-K,
or a reportable event, as that term is defined in Item 304(a)(1)(v) of
Regulation S-K.

OTHER MATTERS

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act requires our directors, executive
officers and persons who own more than 10% of our Common Stock (collectively,
"Reporting Persons") to file reports of ownership and changes in ownership of
our Common Stock. Reporting Persons are required by Securities and Exchange
Commission regulations to furnish us with copies of all Section 16(a) reports
they file. Based solely on its review of the copies of such reports received or
written representations from certain Reporting Persons, we believe that during
the fiscal year ended December 31, 2000, all Reporting Persons complied with
all applicable filing requirements, with the exception of Mr. Cohen,
Mr. Chillingworth and Ms. Drew. Mr. Cohen was required to file a report on Form
4 respecting certain sales of our Common Stock, Mr. Chillingworth and Ms. Drew
were each required to file reports on Form 3. We anticipate filing a report on
Form 5 on Mr. Cohen's behalf, and on Mr. Chillingworth's and Ms. Drew's behalf,
prior to the date of the Annual Meeting.

Other Matters

The Board of Directors knows of no other business that will be presented
at the Annual Meeting. If any other business is properly brought before the
Annual Meeting, it is intended that proxies in the enclosed form will be voted
in respect thereof in accordance with the judgments of the persons voting the
proxies.

It is important that the proxies be returned promptly and that your shares
be represented. Shareholders are urged to mark, date, execute and promptly
return the accompanying proxy card in the enclosed envelope.
