The user computes by himself a derived credential based on the credential issued by the credential authority, and proves to the verifier using the derived credential. If a new user is authorized, other users and the verifier need not update any data. If a user ever authorized is banned, i.e., his/her token is revoked, the credential authority computes the updated accumulator based on the token issued to the banned user, and publishes a revocation increment data comprising the updated accumulator and the increment data about the revoked token. Other users compute their updated credentials by themselves based on the updated revocation increment data received.

Abstract: The invention provides a malleable pseudonym certificate system and method for a communication network. According to one embodiment of the invention, a user acquires a root proof from a trusted entity, generates one or more pseudonym certificates based on the root proof, and sends anonymous public keys each equipped with one pseudonym certificate to verifiers. Through use of the pseudonym certificate, the verifier believes that the user's anonymous public key is certified by the trusted entity. The pseudonym certificate contains no information by which the verifier can figure out the real identity of the user. With the malleable pseudonym certificate system, the trusted entity needs only certify once for the user's root public key. The user can generate by him or herself mass anonymous public keys where each anonymous public key is equipped with a distinct pseudonym certificate.
