为了解决RFID系统的安全和成本问题,提出了一种基于超椭圆曲线密码体制的RFID安全协议.利用新的签密算法,在RFID阅读器和电子标签之间实现了信息的加密和认证.与现有的签密算法比较,该协议具有前向安全和可公开验证,能避免恶意信息的攻击.协议的安全性和性能分析结果表明,该协议达到了RFID系统高隐私安全和低标签成本的结合.
To solve cost and security problems of RFID system,an RFID security protocol based on hyperelliptic curve cryptosystem is proposed.The protocol realizes encryption and certification of data between RFID tag and reader by using new signcryption.The new protocol has the capability of forward secrecy and public verifiability and avoids the attack of evil information compared with the exsiting signcryption.The security and performance of the protocol is analyzed,results prove that the new protocol achieves the integration of low tag cost and high security of RFID system.
