基于RFID技术的分布式密钥安全保护机制

A RFID-Based Security Protection Mechanism with Distributed Cryptographic Keys

文章主要基于RFID技术,实现分布式密钥安全保护机制。文章将密钥拆分成不同的子密钥存储到不同的标签上,通过扫描多个分布式便携电子标签,来获取密钥,在保证密钥安全的同时实现了个性化的终端解锁方式。由于标签具有便携性,所以终端用户可以将其随身携带。由于该机制不改变硬件结构和协议内容,实现方便,成本低廉,有十分光明的应用前景,未来可扩展到其他物联网应用场景下。

This paper is based on the RFID technology, implementing a sort of security protection mechanism with distributed cryptographic keys. We split a cryptographic key into different cryptographic sub-keys stored in different electronic tags. We get the original key by scanning several distributed and portable electronic tags. While guaranteeing the security of a cryptographic key, we implement an individual method to unlock the terminal. Because of the portability of electronic tags, terminal users can carry these tags with themselves. As our widget is implemented easily and cheaply without changing the hardware struct and protocol content, it has a bright application prospect and is extensible to other application field of Internet of things.
