基于非对称密码机制的RFID单向认证方法

Asymmetric Cryptography Based Unidirectional Authentication Method for RFID

针对射频识别(RFID)技术中的认证和隐私保护问题,提出一种基于椭圆曲线的RFID单向认证方法。与其他基于非对称密码认证方法相比,该方法具有更强的安全性、更短的密钥长度和较低的计算量。该方法实现了RFID系统中标签与读写器之间的单向鉴权,并允许标签自动更新密钥以增强认证安全性,还允许标签更新自己的名称和私钥,用以防止被攻击者跟踪,从而解决标签的隐私问题。

Aiming at the problem of authentication and privacy protection in radio frequency identification(RFID)technology,this paper proposes an elliptic curve-based RFID one-way authentication method.Compared with other methods based on asymmetric cryptography,this method has stronger security,shorter key length and lower computational complexity.The method implements one-way authentication between the tag and the reader in the RFID system and allows the tag to automatically update the key to enhance authentication security.The method also allows the tag to update its own name and private key,thereby preventing the attacker from tracking and thus addressing the privacy of the tag.
