摘要
基于椭圆曲线密码体制提出一种新的签密算法,并以RFID系统中阅读器和电子标签的签密过程为应用基础,解决RFID系统中加密和认证不能同时进行的安全问题;该算法借助椭圆曲线密码体制的难解性,以其密钥短、安全性高和灵活性强的特点而优于DLP设计方案;具有更小的通信代价和更高的安全性能。
Based on signcryption process of reader and label in the RFID system,this paper proposes a signcryption algorithm based on elliptic curve crypto system,and solves a security problem about asynchronous of encryption and certification in RFID system.The algorithm uses the obscure of elliptic curve crypto system,and has an advantage of DLP design with its shorter key,higher security and flexibility.Most of all,it have a lower communication cost and higher-level security.
