摘要: We develop an efficient identity based signature scheme on pairings whose security relies the hardness of Diffie-Hellman problem in random oracle model. describe how this is obtained as a special version more general generic which yields further new provably secure schemes if are used. The also includes traditional public key schemes. discuss issues escrow and distribution keys to multiple trust authorities. appendix contains brief description relevant properties supersingular elliptic curves Weil Tate pairings.
