Technology advances—such as improving processing power, battery life, and communication functionalities—contribute to making mobile devices an attractive research area. In 2008, in order to manage mobility, the Internet Engineering Task Force (IETF) developed Proxy Mobile IPv6, which is a network-based mobility management protocol to support seamless connectivity of mobile devices. This protocol can play a key role in volunteer computing paradigms as a user can seamlessly access computing resources. The procedure of user authentication is not defined in this standard; thus, many studies have been carried out to propose suitable authentication schemes. However, in the current authentication methods, with reduced latency and packet loss, some security and privacy considerations are neglected. In this study, we propose a secure and anonymous ticket-based authentication (SATA) method to protect mobile nodes against existing security and privacy issues. The proposed method reduces the overhead of handover authentication procedures using the ticket-based concept. We evaluated security and privacy strengths of the proposed method using security theorems and BAN logic.

一种基于安全票据的志愿计算代理移动 IPv6 网络认证机制

技术进步——例如提高处理能力、电池寿命和通信功能——有助于使移动设备成为一个有吸引力的研究领域。2008 年，为了管理移动性，互联网工程任务组 (IETF) 开发了 Proxy Mobile IPv6，这是一种基于网络的移动性管理协议，支持移动设备的无缝连接。该协议可以在志愿计算范式中发挥关键作用，因为用户可以无缝访问计算资源。本标准未定义用户认证的程序；因此，已经进行了许多研究以提出合适的认证方案。然而，在当前的认证方法中，随着延迟和丢包的减少，一些安全和隐私的考虑被忽略了。在这项研究中，我们提出了一种安全和匿名的基于票据的身份验证 (SATA) 方法来保护移动节点免受现有的安全和隐私问题的影响。所提出的方法使用基于票据的概念减少了切换认证过程的开销。我们使用安全定理和 BAN 逻辑评估了所提出方法的安全性和隐私强度。
