摘要
RFID系统中的电子标签在其被使用过程中,电子标签的拥有者会经常发生变化,当拥有者发生变化之后,电子标签的所有权归属者却可能没有发生相对应的变更,将会导致原归属者获取现归属者隐私信息,使得现归属者隐私信息泄露,为解决该问题,提出一种轻量级的所有权安全加密算法,利用变形的哈希函数对所要发送的数据加密,并以密文的方式发送每一个消息。对算法进行安全性分析,表明算法可以抵抗诸如重放攻击、穷举攻击等各种常见类型的攻击,具有较强的安全性。
During the use of electronic tags in RFID systems,the owner of the electronic tag often changes.However,when the owner changes,the ownership of the electronic tag may not have changed accordingly,leading to the original owner obtaining the current owner's privacy information and causing the current owner's privacy information to be leaked.To solve this problem,a lightweight ownership security encryption algorithm is proposed.The algorithm uses a deformed hash function to encrypt the data to be sent and sends each message in ciphertext format.Security analysis of the algorithm shows that it can resist various common types of attacks such as replay attacks and exhaustive attacks,and has strong security requirements.
