METHOD AND SYSTEM WITH AUTHENTICATION, REVOCABLE ANONYMITY AND NON-REPUDIATION

摘要

The access procedure identifies and registers a client and authenticates the client with an Anonymous Certificate of Authority and creates an anonymous signature for the client, which is used to open a session on a auction server (SE). The server can contact the Anonymous Certificate server (ACA) only if it is essential to non-repudiation, using the anonymous signature assigned.
