基于物联网的RFID安全认证技术研究

RFID安全是制约物联网技术发展的关键问题.本文描述了RFID安全现状及系统工作原理,分析了RFID可能存在的各种安全隐患,剖析了RFID高中低级安全认证方法的特点,提出了一种基于动态口令加密算法的RFID安全认证机制,该认证方法利用随机数进行身份验证,利用公共密钥进行动态口令加密.针对RFID体系的安全认证,该算法在防窃听、防拒绝服务、防重写、防伪装、防位置定位上都有较好的效果.

Research on RFID security authentication based on IOT

RFID security is the key ofintemet of things. The paper introduces RFID security and the basic principle, describes the possible attacks, and analyzes the high, middle, low security authentication. It proposed the RFID security authentication system based on dynamic password. It carried on authentication using with random number and dynamic password encryption using by the public key. It has anti-eavesdropping, anti-denial of service preventing rewrite, anti-counterfeiting, anti-location. It proves the feasibility and practicability of the security solution that we have designed.
