供应链环境下安全的RFID认证方案

Security RFID Authentication Scheme in Supply Chains

供应链环境下RFID安全认证方案不仅要保证各节点的隐私安全,还应该满足供应链管理需求。针对现有方案存在不能同时兼顾两者的不足,提出一种基于"双重签名"的认证方案。标签的认证信息先后采用访问密钥和认证密钥进行双重签名生成,只有同时具备这两个密钥才能识别标签身份。该方案既可以实现标签在供应链内的安全传递,又能方便供应链的管理。分析表明,该方案较现有方案优势明显。

Security RFID authentication scheme in supply chains should not only ensure the privacy and security of all the company,but also satisfy the requirement of supply chains management.Aiming at the problem that existing schemes can＇t consider both sides at the same time,the paper proposed an authentication scheme based on ＂double signature＂.The tag authentication message is signed by the access key and the authentication key.Only possessing both two keys can the company identify the tag.This scheme makes tags transfer safety inside the supply chains and makes the supply chains management convenient.Analysis shows that this scheme has clear advantage compared with existing schemes.
