摘要
利用码分多址技术的保密性、抗干扰性和多址通信能力,结合认证密钥和Hash函数,设计了一种适用于RFID系统且具有防碰撞功能的安全认证协议.理论和分析表明:与常用的安全认证协议相比,新协议在保证一定复杂度基础上,不仅能有效地解决标签的碰撞问题,而且可抵抗包括重传、跟踪、阻断和篡改在内的多种攻击手段,尤其针对来自系统内安全威胁,具有一定的安全性和实用性.
In this paper, a novel authentication protocol based on CDMA and Hash function is presented. The new protocol can tackle with the problem of tag collisions and resist several possible attacks, including reply, tracking, blocking, proofing, and inner attacks. Both theory and analysis show that the new protocol, compared with other authentication protocols, improves the security of RFID systems effectively and does not increase the complexity of protocol.
