Mobile edge computing (MEC) allows one to overcome a number of limitations inherent in cloud computing, although achieving the broad range of security requirements in MEC settings remains challenging. In this paper, we focus on achieving mutual authentication with anonymity and un-traceability, as this is crucial in ensuring data security and user privacy. Specifically, we design an identity-based anonymous authenticated key agreement protocol for the MEC environment. The proposed protocol achieves mutual authentication in only a single message exchange round, as well as assures both user anonymity and un-traceability. We then evaluate the security and performance of the protocol, and demonstrate that it achieves the required security properties and outperforms prior approaches in terms of communicational and computational costs.

一种适用于移动边缘计算的安全可靠的基于身份的匿名身份验证方案

移动边缘计算（MEC）可以克服云计算固有的许多限制，尽管在MEC设置中实现广泛的安全要求仍然具有挑战性。在本文中，我们着重于实现具有匿名性和不可追溯性的相互认证，因为这对于确保数据安全性和用户隐私至关重要。具体来说，我们为MEC环境设计了一个基于身份的匿名认证密钥协商协议。所提出的协议仅在单个消息交换回合中即可实现相互认证，并确保用户匿名和不可追踪性。然后，我们评估该协议的安全性和性能，并证明该协议可实现所需的安全性，并且在通信和计算成本方面优于现有方法。
