基于椭圆曲线零知识的RFID双向身份认证

摘要

Within the wider spread of RFID technology, all kinds of identity deception attacks aiming at RFID tags and readers grow up. To ensure the security and privacy in this communication, the RFID tags and readers need to identify them each other, thus the system will create a credible communication channel. This paper proposes a mutual authentication protocol based on el-liptic curve cryptography and zero knowledge authentication, and proposes a dynamic tag-ID technology, solving the sniffing, tracking attacks and other issues efficiently.%　　RFID技术在被广泛应用的同时，各种针对RFID标签与读写器间身份欺骗的攻击层出不穷。为保证通信间的安全与隐秘，需要两者之间相互鉴别身份真伪，从而创造一条可信的通信信道。以椭圆曲线加密体制和零知识身份证明为基础，提出一种标签与读写器双向身份认证的协议，提出一种动态标签ID的方式，更好地解决了嗅探、跟踪攻击等问题。
