                                     THIRD

                             AMENDED AND RESTATED

                        CERTIFICATE OF INCORPORATION OF

                                VERISIGN, INC.

                            a Delaware corporation

                                        

     ONE:  The name of the corporation is VeriSign, Inc. (hereinafter sometimes
referred to as the "Corporation").

     TWO:  The address of the Corporation's registered office in the State of
Delaware is 30 Old Rudnick Lane, in the City of Dover, in the County of Kent.
The registered agent in charge thereof is CorpAmerica, Inc., 30 Old Rudnick
Lane, Dover, Delaware 19901.

     THREE:    The purpose of the Corporation is to engage in any lawful act or
activity for which corporations may be organized under the General Corporation
law of Delaware.

     FOUR: A.  The Corporation is authorized to issue two classes of stock to be
designated, respectively, "Common Stock" and "Preferred Stock."  The total
number of shares which the Corporation is authorized to issue is fifty-five
Million (55,000,000) shares.  Fifty Million (50,000,000) shares shall be Common
Stock, $0.001 par value per share, and five Million (5,000,000) shares shall be
Preferred Stock, $0.001 par value per share.

           B.  The Board of Directors is authorized, subject to any limitations
prescribed by law, to provide for the issuance of shares of Preferred Stock in
series, and by filing a certificate pursuant to the applicable law of the State
of Delaware (such certificate being hereinafter referred to as a "Preferred
Stock Designation"), to establish from time to time the number of shares to be
included in each such series, and to fix the designation, powers, preferences,
and rights of each such series and any qualifications, limitations or
restrictions thereof.  The number of authorized shares of Preferred Stock may be
increased or decreased (but not below the number of shares thereof then
outstanding) by the affirmative vote of the holders of a majority of the
outstanding shares of Common Stock, without a vote of the holders of the
Preferred Stock, or of any series thereof, unless a vote of any such holders is
required pursuant to the terms of any Preferred Stock Designation.

     FIVE: The following provisions are inserted for the management of the
business and the conduct of the affairs of the Corporation, and for further
definition, limitation and regulation of the powers of the Corporation and of
its directors and stockholders:

           A.  The business and affairs of the Corporation shall be managed by
or under the direction of the Board of Directors. In addition to the powers and
authority expressly conferred upon them by statute or by this Third Amended and
Restated Certificate of Incorporation or the Bylaws of the Corporation, the
directors are hereby empowered to exercise all such powers and do all such acts
and things as may be exercised or done by the Corporation.

           B.  The directors of the Corporation need not be elected by written
ballot unless the Bylaws so provide.

 
          C.    Any action required or permitted to be taken by the stockholders
of the Corporation must be effected at a duly called annual or special meeting
of stockholders of  the Corporation and may not be effected by any consent in
writing by such stockholders.

          D.    Special meetings of stockholders of the Corporation may be
called only by either the Board of Directors pursuant to a resolution adopted by
a majority of the total number of authorized directors (whether or not there
exist any vacancies in previously authorized directorships at the time any such
resolution is presented to the Board for adoption), the Chief Executive Officer
or the President.

    SIX:  A.    The directors, other than those who may be elected by the
holders of Preferred Stock under specified circumstances, shall be divided into
three classes with the term of office of the first class (Class I) to expire at
the annual meeting of the stockholders held in 1998; the term of office of the
second class (Class II) to expire at the annual meeting of stockholders held in
1999; the term of office of the third class (Class III) to expire at the annual
meeting of stockholders held in 2000; and thereafter for each such term to
expire at each third succeeding annual meeting of stockholders after such
election. All directors shall hold office until the expiration of the term for
which elected, and until their respective successors are elected, except in the
case of the death, resignation, or removal of any director.

          B.    Subject to the rights of the holders of any series of Preferred
Stock then outstanding, newly created directorships resulting from any increase
in the authorized number of directors or any vacancies in the Board of Directors
resulting from death, resignation or other cause may be filled (a) by the
stockholders at any meeting, (b) by a majority of the directors, although less
than a quorum, or (c) by a sole remaining director, and directors so chosen
shall hold office for a term expiring at the next annual meeting of stockholders
at which the term of office of the class to which they have been elected
expires, and until their respective successors are elected, except in the case
of the death, resignation, or removal of any director.  No decrease in the
number of directors constituting the Board of Directors shall shorten the term
of any incumbent director.

     SEVEN:     The Corporation shall have a perpetual existence.

     EIGHT: A.  Exculpation.  A director of the Corporation shall not be
                -----------                                             
personally liable to the Corporation or its stockholders for monetary damages
for breach of fiduciary duty as a director, except for liability (i) for any
breach of the director's duty of loyalty to the Corporation or its stockholders,
(ii) for acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of law, (iii) under Section 174 of the
Delaware General Corporation law or (iv) for any transaction from which the
director derived any improper personal benefit.  If the Delaware General
Corporation law is hereafter amended to further reduce or authorize, with the
approval of the Corporation's stockholders, further reductions in the liability
of the Corporation's directors for breach of fiduciary duty, then a director of
the Corporation shall not be liable for any such breach to the fullest extent
permitted by the Delaware General Corporation Law as so amended.

            B.  Indemnification.  To the extent permitted by applicable law,
                ---------------
this Corporation is also authorized to provide indemnification of (and
advancement of expenses to) agents (and any other persons to which Delaware law
permits this Corporation to provide 

 
indemnification) through bylaw provisions, agreements with such agents or other
persons, vote of stockholders or disinterested directors or otherwise, in excess
of the indemnification and advancement otherwise permitted by Section 145 of the
Delaware General Corporation Law, subject only to limits created by applicable
Delaware law (statutory or non-statutory), with respect to actions for breach of
duty to the Company, its stockholders, and others.

          C.  Effect of Repeal or Modification.  Any repeal or modification of
              --------------------------------                                
any of the foregoing provisions of this Article Eight shall not adversely affect
any right or protection of a director, officer, agent or other person existing
at the time of, or increase the liability of any director of the Corporation
with respect to any acts or omissions of such director occurring prior to, such
repeal or modification.
