摘　　要：小区重选算法是决定终端能否持续获得良好服务的关键技术,设计一种增强小区重选算法安全性的协议,使用户的信号质量和通信安全同时得到保障至关重要。为此,基于物理不可克隆函数提出一种小区重选算法安全协议,达到仅经过三轮交互即完成认证的目的。以同频小区重选为例描述协议的具体过程,并通过GNY逻辑进行形式化分析,证明其能实现用户设备和基站的双向认证,同时可抵抗克隆攻击、重放攻击和中间人等攻击,具有较好的安全性和保密性。Cell reselection algorithm is the key technology for the terminal to continue to obtain good service.It is very important to design a protocol to enhance the security of the cell reselection algorithm,so that the user’s signal quality and communication security are guaranteed at the same time.In this paper,a protocol to enhance the security of cell reselection algorithm is proposed based on Physical Unclonable Function(PUF),which can achieve the purpose of certification after only three-round interaction.The specific process of protocol is discussed with the same frequency cell reselection as an example.The protocol is formally analyzed by GNY logic,and is proved that it can realize the bidirectional authentication of User Equipment(UE)and Base Station(BS),and resist attacks such as clone attack,replay attack and family family,which has better security and confidentiality.
