Certificateless Group Signature Scheme from Bilinear Pairings

Certificateless public key cryptography solve the certificate management problems of the traditional public key cryptography, also overcomes the problems public key escrow in identity based cryptography. A group signature scheme allows a group member to sign messages anonymously on behalf of the group. This paper introduces a certificateless group signature scheme from bilinear pairings. This scheme has the advantages of certificateless public key cryptography,meet the security requirements of group signature, and can easily achieve the group members to join and withdraw, track of group members are more simple.
