Abstract: This paper proposes a certificateless verifiable ring signature scheme. It is based on the concepts of certificateless cryptosystem and verifiable ring signature scheme. The scheme has the properties of ring signature scheme, if necessary, the actual signer can prove to the verifier that he(she) actually signed the signature. The scheme is based on certificateless cryptosystem, so it can overcome the key escrow of ID-based cryptosystem, and avoid the public key management and storage of certificate-based cryptosystem.

Key words: ring signature, certificateless cryptosystem, verifiable ring signature, Computational Diffie-Hellman Problem(CDHP)

摘要： 将无证书的密码体制与可验证环签名相结合，提出一个无证书的可验证环签名方案。方案具有环签名的性质，在需要时，真实签名者还可向验证者证明自己的身份。方案基于无证书的密码体制，克服了基于身份的密码体制的密钥托管问题，避免基于证书密码体制的公钥存储和管理问题。
