An Identity-Based Authenticated Key Agreement Protocol without Bilinear Pairing

摘要: 鉴于目前大多数基于身份的认证密钥协商(ID-AK)协议需要复杂的双线性对运算，该文利用椭圆曲线加法群构造了一个无双线性对的ID-AK协议。协议去除了双线性对运算，效率比已有协议提高了至少33.3%；同时满足主密钥前向保密性、完善前向保密性和抗密钥泄露伪装。在随机预言机模型下，协议的安全性可规约到标准的计算性Diffie-Hellman假设。Abstract: Most available Identity-based Authenticated Key agreement (ID-AK) protocols require expensive bilinear pairing operation. This paper proposes a pairing-free ID-AK protocol from additive elliptic curve group. The new protocol eliminates the pairing operations, and reduces overall computation time by at least 33.3 percent compared with previous ID-AK protocols. The new protocol also satisfies master key forward secrecy, perfect forward secrecy and key compromise impersonation resilience. The security of the proposed protocol can be reduced to the standard Computational Diffie-Hellman assumption in the random oracle model.
