VCC leverages the underutilized storage and computing resources of vehicles to collaboratively provide traffic management, road safety, and infotainment services to end users, such as drivers and passengers. It is a hybrid technology that improves the resource utilization on vehicles and is able to perform complex computing tasks that cannot be handled by a single vehicle. Despite the appealing advantages, security and privacy threats are severe in VCC due to the sharing of resources among unfamiliar vehicles. In this article, we identify security goals for the interoperability with VCC and provide an AKA framework for VCC. Specifically, we first present the research challenges and open problems for designing a reliable AKA with strong security guarantees for VCC. Then we propose an integrated AKA framework that integrates the single-server 3-factor AKA protocol and the non-interactive identity-based key establishment protocol, and evaluate its performance based on a simulated experimental platform. Finally, several interesting issues are discussed to light up the further research directions on AKA for VCC.

车载云计算的集成身份验证和密钥协议框架

VCC利用未充分利用的车辆存储和计算资源，共同为最终用户（例如驾驶员和乘客）提供交通管理，道路安全和信息娱乐服务。它是一种混合技术，可提高车辆的资源利用率，并能够执行单个车辆无法处理的复杂计算任务。尽管具有吸引人的优势，但由于不熟悉的车辆之间共享资源，VCC中的安全性和隐私威胁仍然很严重。在本文中，我们确定了与VCC互操作性的安全目标，并提供了VCC的AKA框架。具体来说，我们首先介绍设计可靠的AKA并为VCC提供强大安全保证的研究挑战和未解决的问题。然后，我们提出了一个集成的AKA框架，该框架将单服务器3因子AKA协议和基于非交互式身份的密钥建立协议进行了集成，并在模拟实验平台上评估了其性能。最后，讨论了一些有趣的问题，以阐明针对VCC的AKA的进一步研究方向。
