摘　　要：由于无线射频识别(RFID)系统资源的限制,现有组证明协议大多采用对称密码算法,会带来安全和隐私保护方面的问题。为此,将公钥密码算法引入到组证明协议设计中。针对基于椭圆曲线密码(ECC)的组证明协议存在易受跟踪攻击的问题,提出一种改进方案,并对其安全性进行分析。分析结果表明,该协议能够抵抗跟踪攻击、伪造证明攻击、重放攻击和假冒攻击,具有较好的安全性,适合于RFID系统应用。Due to the scarceness of resources,most of the proposed grouping-proof protocols are designed using symmetric key cryptographic algorithms,but this may bring security and privacy issues.This paper proposes public-key cryptographic algorithms to satisfy these requirements.In order to overcome the problem of vulnerable to tracking attack of grouping-proof protocol based on Elliptic Curve Cryptography（ECC）,an improved scheme is presented to resist tracking attack and analyze the security and performance of the protocol.Analytical results show that the proposed scheme is proved secure against tracking attack,forged proofs attack,impersonation attack and replay attack,and can be applied to Radio Frequency Identification（RFID） system.
