The process utilizes a nonce of an authentication protocol request message (nonce_A) to derive the nonce for the revocation status protocol request (nonce_S) to reduce the number of message exchanges needed between the client and the verifier devices, and a mechanism to send the nonce (nonce_S) prior to actual authentication protocol execution to ease the connectivity requirement of client device from on-demand connectivity to periodic connectivity. Similar functionality is achieved using a random seed established between the verifier and client. The verifier picks a seed for random number generation and sends that seed to the client. The client derives the nonce_S from the seed before status protocol execution, and the verifier derives the nonce_S from the seed before proxied status response verification."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Mechanisms for certificate revocation status verification on constrained devices","description":"A process is provided for communication security certificate revocation status verification by using the client device as a proxy in online status verification protocol.
