Ultra-dense networks (UDN) are considered as one of the key technologies for advancing the widespread deployment of 5G networks. To provide continuous and reliable connectivity to user devices and to achieve the integrity and authenticity of communication, UDN needs to address the challenges related to authentication and authorization of information. Existing authentication and key agreement (AKA) schemes are not appropriate for the ultra-dense deployment of access points due to excessive authentication and/or computation overhead. This paper proposes a novel lightweight batch authentication and key agreement (LBAKA) scheme for user-centric UDN scenarios by adopting lightweight batch authentication solution and one-to-one key agreement, and by using mutual authentication to verify the credibility of both sides of the communication. The proposed LBAKA can maintain privacy of identity information under replay, impersonation and man-in-the-middle attacks in user-centric UDNs. In terms of computation and communication overhead, our simulation results show that LBAKA outperforms other similar schemes in user-centric UDNs.

以用户为中心的超密集网络的轻量级批处理 AKA 方案

超密集网络(UDN)被认为是推动 5G 网络广泛部署的关键技术之一。为了向用户设备提供持续可靠的连接并实现通信的完整性和真实性,UDN 需要解决与信息认证和授权相关的挑战。由于过多的身份验证和/或计算开销,现有的身份验证和密钥协商 (AKA) 方案不适合接入点的超密集部署。本文针对以用户为中心的 UDN 场景,提出了一种新的轻量级批量认证和密钥协商 (LBAKA) 方案,采用轻量级批量认证方案和一对一密钥协商,并通过相互认证来验证双方的可信度。沟通。提议的 LBAKA 可以在以用户为中心的 UDN 中的重放、假冒和中间人攻击下保持身份信息的隐私。在计算和通信开销方面,我们的模拟结果表明 LBAKA 在以用户为中心的 UDN 中优于其他类似方案。
