Abstract

Systems and methods for maintaining cryptographic revocation lists are provided. A method includes determining that a cryptographic certificate (152) should be revoked. Based on the determination, a certificate revocation message is broadcast to a network of client devices (140). The certificate revocation message includes an identifier associated with the cryptographic certificate. Each client device that receives the certificate revocation message updates a list (144) maintained by the client device. The updated list indicates that the cryptographic certificate (152) identified by the identifier is no longer valid.
