Abstract: In this work we provide a formal analysis of the security of an identity-based ring signature scheme proposed by Zhang and Kim in [10]. We first define the security requirements that this kind of schemes must satisfy; or in other words, the capabilities and goals of the most powerful attacks these schemes must remain secure against. Then we prove, in the random oracle model, that the above-mentioned scheme is secure against the defined attacks, assuming that the Computational Diffie-Hellman problem is hard to solve.
