摘要
基于批量处理的特性,提出一个适用于供应链的可扩展的读写器-标签双向认证协议。在该协议中,后端数据库识别一个标签只需运行3次哈希函数和O(logn)次比较大小的运算,标签的计算量和已有的不可扩展的协议相当。提出的协议显著提高了射频识别RFID(Radio Frequency Identification)供应链管理系统的效率,并且满足其安全需求。
In this paper,we propose a scalable reader-tag mutual authentication protocol suitable for efficient supply chain management, which is based on supply chain' s batch processing property. In the protocol, the backend database only needs to perform 3 times of hash function and O( log n) operations of size comparing for authenticating a tag,while the computation cost of the tag is comparable with the existing unscalable protocols. The proposal remarkably improves the RFID supply chain management system' s efficiency, and also meets its security requirements.
