New X.509-based mechanisms for fair anonymity management
We extend the X.509 infrastructure to support anonymity and unlinkability revocation. The additional functionality is included by means of OCSP and CRL extensions. Also, a new protocol, Anonymous Certificate Fairness Protocol (ACFP) is proposed. ACFP provides an X.509-like mechanism to convey evidence proving a misbehavior. The work includes experimental measures obtained through a prototype of our proposal.
