轻量级RFID双向通信认证协议优化方案

以轻量级RFID双向通信认证的设计与实现为研究目标，针对目前存在的轻量级RFID算法空白，所有权转移问题难以解决，现有协议未经过实际检验等问题，基于ECC算法机制，开展设计研究，取得了轻量级RFID双向通信认证协议的逻辑设计、源代码编写、硬件调试、上位机软件编写、可靠性测试等成果，可直接投入实际运用。文章从现有RFID安全认证协议出发，精心论证，认真分析，确保每一步认证的安全性，实现了授权访问、双向认证、标签匿名性、可用性，有效地保护了标签和数据库双向安全，满足RFID系统的安全需求。

An Optimal Design to Lighten the Agreement of Bidirectional Identiifcation on RFID

Treating the design and realization of Lighten the Agreement of Bidirectional Identiifcation on RFID as our study destination, we use the ECC ALG machining as the basement to start this research. The study is developed to solve some important questions which still exist in this field, such as filling the blank space in ALG on RFID, working out the dififculty of the change of the ownership and that the present agreement hasn’t been tested. At present, we have got success of logic project, original code’s development, debugging the hardware, redacting the software and testing the realibility, of which all can be put into practice directly. The positive result is based on current agreement to RFID safety and has made the impower visit, the bidirectional attestation and the mark’s anonymity realized, which can effectively protect the bidirectional safety of the tag and database. Through our serious study and analysis, we believe we have made the whole process reliable. In short, this product can satisfy the safety need of the RFID system.
