摘要
随着RFID系统应用的不断扩大,RFID的安全问题也越来越受到人们的关注。基于Hash函数的RFID安全协议以其低成本的优势得到了广泛的应用,但其安全性能尚不完善。文章在分析已有的Hash Lock安全协议的基础上,提出了3种基于Hash函数的R FID安全认证协议IHSAP、IHSAP2和IHSAP3。通过对其进行安全性分析和性能评价可知,IHSAP3性能最好,它可以很好地解决了R FID系统中的信息泄露、位置跟踪、假冒攻击、重放攻击等安全与隐私问题。
With the growing application of RFID systems, RFID security issues are also more and more attention. Hash-based RFID security protocol has been widely used with its low-cost, but its safety performance is not perfect. The p2per proposed three kinds of hash-based security authentication protocol based on the analysis of existing security protocols. On the basis of the security and performance evaluation of these protocols, IHSAP3 is the best in performance, it can prevent many security including information leakage, location tracingoreplay attack,etc.
