摘要
在与金钱或资产相关的RFID系统中,带有身份认证和密码体制的高档电子标签是必不可少的,同时RFID系统又是资源受限的;把导出密钥的相互鉴别和高级加密标准(AES)算法相结合可以进行身份认证,能够抵抗回放攻击,体现了分级密钥的原则,密码算法也保证了很高的安全性;对AES算法进行工程优化设计,使之能够以很少的资源在8位单片机PIC16F873A中实现,加解密速度可以达到58 kb/s,这在资源受限的嵌入式应用中是非常适合的。
the high-grade electronic label of the identity authentication and eneryption is essential in the RFID system which relates with money or assets, and the RFID system resources are limited. It can resist repeat attacks, embody the principles of key classification and ensure high security for eneryption algorithms by combining the identification of educed key and AES algorithm. It can realized in 8-bit singleehip PIC16F873 by AES optimization, and its deeryption speed can reach 58kb/s. so it is very appropriate for embedded application.
