摘要: 身份认证和密钥交换技术是保证无线通信安全的重要手段。针对非接触式智能卡的需求,提出一种基于有限计算能力的相互认证密钥交换协议。在随机预言模型下证明该协议的安全性,结果表明,该协议可有效抵抗重放攻击、中间人攻击和交错攻击,计算量较小,实用性较高。

Abstract: Identity authentication and key exchange technology is the important means to ensure wireless communication security. Aiming at the demand of contactless smart card, this paper proposes a new mutual authentication key exchange protocol based on low power computing devices. The protocol is secure against replay attacks, man-in-the-middle attacks and interleaving attacks, and the security of the protocol is proved in the random oracle model. Result shows that the designed protocol is of good feasibility and needs smaller computing power.

Key words: key exchange, identity authentication, random oracle model, contactless smart card
