Efficient identification scheme with bilinear map
利用双线性映射构建高效身份认证方案

Concerning the discrete logarithm problem of elliptic curve and bilinear mapping,an identification scheme was proposed,and then it was extended to multi-KGC situation.The proposed scheme required less computation and communication than the existing ones and realized mutual authentication.Given the condition of the intractability of the elliptic curve discrete logarithm problem,the proposed scheme was proved secure against forged user attack,impersonation attack and replay attack.
