Utility
Systems and methods for addressing cryptoprocessor hardware scaling limitations
30 May 23
The present disclosure is directed to systems and methods to address cryptoprocessor hardware scaling limitations, the method including the steps of establishing a communication path between a centralized server and a client device; generating, by the centralized server, a nonce for transmission to the client device, wherein the nonce is associated with an active time interval and corresponds to one of an existing nonce or a new nonce; transmitting the nonce to the client device; receiving a signed attestation result that includes the nonce from the client device, wherein, the signed attestation result comprises a previously-generated signed attestation result if the nonce corresponds to the existing nonce previously received by the client device; and the signed attestation result comprises a new signed attestation result if the nonce corresponds to the existing nonce newly received by the client device or corresponds to the new nonce.
