Abstract (en)
[origin: WO2006035159A1] The invention relates to a public key cryptographic method and system, a certification server and memories adapted for said system. In said public key cryptographic system, there is insufficient information contained in an electronic public key certificate alone to retrieve the public key. The inventive system comprises at least a second memory (52, 72) in which complementary information is stored, which can be used to retrieve the public key when used together with the information contained in the certificate.According to the invention, access to said complementary information is reserved to a limited number of authorised terminals among the group of terminals that can verify the certificate signature.
