基于ECC的轻量级射频识别安全认证协议

Security authentication protocol for lightweight radio frequency identification based on ECC

针对基于椭圆曲线密码体制（ECC）的射频识别安全认证协议无法抵制服务器假冒攻击的的问题,对认证过程进行改进,设置用于实现标签对服务器认证的环节,提出基于ECC的轻量级射频识别安全认证协议.改进后的方案满足抗服务器假冒攻击、抗标签假冒攻击等各项射频识别认证协议的安全特性.计算及通信开销分析表明：该协议在提供更高的安全性的同时能很好地应用于资源受限的射频识别认证.

According to security of radio frequency identification（RFID） authentication protocol based on elliptic curve cryptography（ECC） could not resist server spoofing,progress for the tags authenticating the server was set to the original protol andan improved RFID authentication scheme based on ECC was proposed. Security analysis was made to show that the proposed scheme could provide server spoofing attack resisting,tag masquerade attack resisting and other security properties of a RFID authentication protocol. Comparisons of computational cost and communicational cost demonstrate that the proposed scheme is suited for RFID tags with the scarceness of resources.
