基于多密钥加密算法的RFID安全认证协议研究

Security Authentication Protocol of RFID Based on Multi-key Encryption Algorithm

在传统的三次认证协议的基础上,结合多密钥加密的思想,提出了一种改进的多密钥加密认证算法,可有效地弥补传统认证技术的缺陷,极大地增强RFID系统中阅读器和不同标签互相认证的安全性.

Based on the traditional three authentication protocols,combined with the idea of multi-key encryption,an improved multi-key encryption and authentication algorithms is presented.The algorithm can effectively improve the deficiencies of the traditional authentication technology,and greatly improves mutual authentication security of the reader and different labels in RFID system.
