WebAlthough achieving anonymity can be an important design criterion in cryptographic systems, it comes at a cost. If the systems are not carefully designed, the overall security of the system could be compromised. Our goal is to develop mathematical techniques that enable anonymity in cryptographic systems without compromising the security. WebPseudonymity is the near-anonymous state in which a user has a consistent identifier that is not their real name: a pseudonym. In pseudonymous systems, real identities are only available to site administrators.
