供应链环境下通用可组合安全的RFID通信协议

供应链管理是RFID技术的主要应用领域之一,但是目前该领域对基于RFID技术的安全机制还没有较深入的研究.供应链环境的特定安全需求决定了无法直接应用已有的各种RFID安全机制.该文定义了供应链环境下RFID通信协议必须满足的安全需求,提出了一个可以满足这些安全需求的通用可组合安全模型,设计了一个可以实现该模型的轻量级RFID通信协议.协议的设计和证明采用模块化的方法,并可以保证在复杂网络环境下的安全运行.文章进一步对不可链接性进行了形式化定义,并根据安全属性对典型的RFID通信协议进行分类.

A Universally Composable Secure RFID Communication Protocol in Supply Chains

Supply chain management is the major field for RFID application.However,little work has been conducted to address the security issues in this context.Existing RFID solutions cannot be applied directly in this field because of a set of special RFID security requirements to be addressed for supply chain management.The major contribution of this paper is to identify the unique set of security requirements for secure RFID communications in supply chains,propose a universally composable model that satisfies the security requirements,and design a lightweight protocol that realizes the universally composable model.This paper further defines the security requirement of unlinkability,and classifies the typical RFID protocols according to the security requirements.
