Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: Featured with anonymity and spontaneity, ring signature has been widely adopted in various environments to offer anonymous authentication. To simplify the certiflcate management in traditional public key infrastructure (PKI) and solve the inherent key escrow problem in the Identity-based cryptography, Qin et al. propose a pairingfree ring signature scheme in the certiflcate-based cryptosystem recently. Unfortunately,  demonstrate that their scheme is not secure against the malicious certiflcate authority (CA) and key replacement attacks by giving concrete attack. Concretely, a malicious certiflcate authority (CA) can forge a signature on arbitrary message in name of any user’s identity and a uncertifled user is also able to forge a message.
