【摘要】 在基于RFID技术的商业活动中,一项非常重要的任务是保护供应链上各个企业的商业秘密不因RFID标签所有权的转换而带来风险.基于Hash函数和对称密码体制,提出了一种适合于供应链环境的轻量级RFID标签所有权转换协议.协议具有抗重放攻击、抗异步攻击、抗假冒攻击、抗内部攻击等特性,并能确保前向、后向隐私安全性.与现有典型的RFID标签所有权转移协议相比,协议的安全性、隐私性好,效率高,能保护企业的商业秘密,具有很好的现实意义.更多还原

【Abstract】 In the commercial activity based on RFID technology,a very important task is to protect the business secrets of each enterprise for the supply chains from risk because of the transformation of the ownership of the RFID tag. Based on the Hash function and symmetric cryptosystem,this paper puts forward a kind of lightweight RFID tag ownership transfer protocol suitable for the supply chain environment. This protocol has the characteristics of resisting replay attack,asynchronous attack,counterfeit attack,internal attack and so on,and can ensure the forward and backward privacy security. Compared with existing typical RFID tag ownership transfer protocols,this protocol is better owing to its security,privacy and efficiency,to protect the business secrets of the enterprises,and hence it has the very good practical significance.更多还原
