Efficient Certificateless Ring Signature Scheme
摘要
Abstract
This paper studies ring signature in the newly proposed certificatelss public key setting. Due to the practical application of the ring signature, using bilinear maps, it constructs a certificateless ring signature scheme. It is proved secure in the strong security model. In the certain anonymous universal set, it just needs one pairing operation in its signing and verification phases. The analysis shows that the scheme satisfies all the security requirements. The security of the scheme is based on the fact that computational Diffie-Hellman problem is hard. It may have practical application in electronic election and electronic auction, etc.关键词
