RFID安全认证协议研究

无线射频识别(RFID)技术的广泛应用给人们的生活带来了极大方便,但RFID系统中的安全隐患也应得到重视。分析了几种常用的RFID安全认证协议,针对密钥矩阵安全认证协议中密值更新出现不同步的问题提出了一种自同步的安全认证协议。当标签和数据库之间的密值更新出现不同步时,该协议能够自动使标签和数据库重新同步,有效解决标签和数据库之间密值更新不同步的问题。

The Research on Cryptographic Protocols for RFID

Security problems of RFID system should be paid attention,while the widely used of Radio Frequency Identification(RFID)technology is brought great convenience to people’s life.Several common security authentication protocols for RFID system are analyzed.Given the asynchronous problem of the secret value updating in tag and database of the key matrix security authentication protocol,a self synchronous security authentication protocol is put forward.When the secret value in the tag and database update asynchronously,the new protocol automatic can make the key synchronize automatically,and the asynchronous problem of the secret value updating in tag and database is solved effectively.
