摘　　要：RFID系统包含对象数量庞大,实现安全的数据传输离不开大量密钥的分发、存储与销毁。将基于对称密钥加密的,可以同时完成通信双方身份认证与密钥协商的安全虚-S盒技术进行相应改进,结合RFID系统安全的需求,设计一个针对RFID系统的密钥管理机制。新的机制由会话双方协商出的安全虚S-盒为RFID系统的通信快速的产生大量随机的会话密钥,且不需要可信第三方的参与。RFID system contains a large number of objects, to obtain safety data transmission requires the distribution, storage and destruction of a plenty number of keys. Based on safety virtual S-box which is used for symmetric key encryption algorithm and can simultaneously com-plete the identity authentication with key agreement of both sides of the conversation. According to the requirement of RFID system secu-rity, designs a key management mechanism for RFID system. The new mechanism can generate a large number of randomized session keys in a short time by safety virtual S-box, while does not require the participation of trusted third party.
