Song Ru-shun · Jisuanji gongcheng · 2009
This paper propose a secure and efficient certificateless group signature scheme.It not only enjoys all the security requirements of a group signature,but also is a dynamic group signature scheme that allows users to join or leave the group freely without updating the group public key and other group members’ private signing key.The length of the signature is independent of the numbers of the group members.The security of the scheme is based on the fact that Computational Differ-Hellman Problem and inverse computational Differ-Hellman problem are hard.
