摘　　要：随着物联网应用的飞速发展,射频识别(RFID)技术作为其重要组成部分拥有了广阔的发展前景。选取一种轻量级RFID协议强认证强完整性协议即SASI进行研究及改进,推出了一种新的安全协议RSASI。它克服了原协议不能防御攻击读写造成读写器中与标签中信息更新不同步的问题和拒绝服务攻击等缺陷,仅增加少量计算量和存储空间,较大幅度地提高了其安全性。采用可编程门阵列及Verilog HDL编程技术,实现了轻量级安全新协议的通信过程,证明此协议具有低成本、低功耗、高安全性、高效率等特点。With the rapid development of the Io T（Internet of things）, RFID（Radio Frequency Identification）technology as its important component has broad development prospects. A lightweight RFID protocol, that is, Random Strong Authentication and Strong Integrity（SASI）,is chosen for study and improvement, and based on this a new security protocol RSASI is proposed, which overcomes the defects that the original protocol cannot resist the read-and-write the attack.This may result in label information update non-synchronization and denial-of-service attack. Only by increasing a small amount of computation and storage space, the safety could be greatly improved. By adopting FPGA and Verilog HDL programming techniques, the new lightweight security protocol for the communication process is implemented, and the agreement proves to be of low cost, low power consumption, high safety, high efficiency and so on.
