摘要
本文提出了采用轻量级(密码编制简单、安全性高、运算速度快的单钥密码算法,如:RC4、RC5、SMS4算法等)加密技术,并采用一种安全单钥管理技术来解决轻量级密码的密钥更新管理的难题,在传感器或RFID读卡器设备端的智能芯片里和物联网认证中心端加密卡芯片里,建立传感设备认证、签名和加密协议、签名验证和解密协议,保证物联网感知层的设备可信,保证传感信息可信、完整和安全保密,从而,建立物联网感知层的信息安全系统。
This paper uses the lightweight （simple cry high security and fast speed single-key cryp-tographic algorithms such as： RC4,RC5,SMS4 etc.） cryptography, and a security single-key management tech-nology to solve the key update management problems of lightweight cryptography.In smart chip of sen-sor/RFID reader device and encrypt card of the authentication center in the intemet of things（IoT）,the device authentication,signature/verification and encryption/decryption protocols are established to ensure the device of sensing layer in lot is credible, and sense information is credible,integral and confidential. Thus, an informa-tion security for perception layer of loT is built.
