改进的物联网中电子票据安全认证协议

IMPROVED SECURITY AUTHENTICATION PROTOCOL OF ELECTRONIC BILL IN INTERNET OF THINGS

为保障电子票据系统中用户的隐私信息安全,提出一种超轻量级的安全认证协议,用于保护用户的隐私。安全认证协议采用循环移动置换运算对传送信息加密,循环移动置换运算基于位运算实现,可使得安全协议达到超轻量级;循环移动置换运算根据加密信息自身汉明重量的值不同,进行两种完全不同的循环移动操作,待循环移动操作完成,再次进行置换操作。对安全协议进行安全性分析及性能分析,安全协议具备超轻量级的特征之外,能够抵抗攻击者发起的常见类型的攻击手段,满足电子票据系统的安全需求。

In order to ensure the privacy information security of users in the electronic bill system,an ultra-lightweight security authentication protocol is proposed to protect the privacy of users.The security authentication protocol encrypted the transmission information with the cyclic mobile replacement operation,which was realized based on the bit operation,so that the security protocol could reach the ultra-lightweight level.The cyclic mobile replacement operation performed two completely different cyclic mobile operations according to the Hamming weight value of the encrypted information itself,and the replacement operation was carried out again after the cyclic mobile operation was completed.The security analysis and performance analysis of the security protocol show that the security protocol has the characteristics of ultra-lightweight,which can resist the common types of attacks launched by attackers and meet the security requirements of the electronic bill system.
