Abstract

Cryptographic methods and apparatus are disclosed that enable formation and issuance of secret-key certificates. In contrast to the well-known cryptographic technique of public-key certificates, where a public-key certificate is a digital signature of a certification authority on a public key, pairs consisting of a public key and a corresponding secret-key certificate can be generated by anyone. However, triples consisting of a secret key, a matching public key and a secret-key certificate corresponding to the public key, can only be generated when the certification authority is involved. Also described are applications of secret-key certificates to public-key directories and to restrictive blind issuing protocols.
