摘　　要：针对现有标签认证存在的效率不高和安全威胁等问题,文中提出了一种新的标签群组认证方案。该方案中,采用随机数和聚合哈希函数技术,将标签分组,每组共享一个组秘钥。充分利用群组秘钥和标签私有秘钥之间关系,采用聚合哈希技术,减少阅读器和服务器之间的通信次数,在满足安全性和隐私等方面要求的前提下,该方案认证效率较高,并通过模拟仿真实验对方案进行验证。结果表明,该方案在认证效率和安全性方面都优于其他群组认证方案,且认证全过程所需时间花费比现有的认证方案降低了20%以上。A new tag group authentication scheme is proposed to solve the problem that the existing tag authentication is inefficient and the security threat.In this scheme,the random number and the aggregate hash function technique are used to group the labels,each group sharing a group key.The use of aggregate hash technology to reduce the number of communications between the reader and the server,to meet the security and privacy requirements under the premise of the program certification efficiency than High,and through simulation experiments to verify the program.The results show that the proposed scheme is superior to other group authentication schemes in terms of authentication efficiency and safety,and the time required for the whole process of certification is reduced by more than20%compared with the existing certification scheme.
