Abstract
A Group signature protocol is a cryptographic scheme that decouples a user identity and location from
verification procedure during authentication. In a group signature scheme, a user is allowed to generate
signatures on behalf of other group members but identity and location information of the signer is not known by
a verifier. This ensures privacy, authentication and unlinkability of users. Although group signature is expensive
to implement, its existential anonymity, non-repudiation and untraceablility properties make it attractive
especially for resources-constrained devices in wireless network. A general group signature scheme usually
contains six basic phases: setup (or key generation), join, message signing (or signature generation), signature
verification, open and user revocation. In this paper, an evaluation of the performance of group signature based
on three of the phases mentioned above is considered and its security in wireless networks examined. The key
generation, signing and verification algorithms are implemented in Java 8. A proof of security of group signature by implication is also presented.
