A provably secure identity-based proxy ring signature based on RSA
2014
Security and Communication Networks
Proxy ring (anonymous proxy) signatures allow an entity to delegate its signing capability to a group of entities (proxy group) such that only one of the members in the proxy group can generate a proxy signature on behalf of the delegator while privacy of the proxy signer is protected. Identity-based versions of proxy ring signatures employ identity strings in place of randomly generated public keys. Our contribution is two-fold. First, we formalize a security model for identity-based proxy
