In the next few years, the mobile pay‐TV systems will be very popular due to their extensive applications. Providing security and privacy are the most challenging issues in the secure development of mobile pay‐TV systems. To avoid unauthorized access to mobile pay‐TV services, it is very important to authenticate the mobile users and the head end system (HES) in an anonymous manner. Even though several authentication schemes were proposed to provide anonymous authentication, the previously proposed schemes are not fit for mobile pay‐TV applications due to their high computational complexity. Hence, a computationally efficient anonymous authentication scheme is proposed in this article for secure service provision in mobile pay‐TV systems. The proposed authentication scheme can effectively authenticate both the mobile users and the HES with low computational cost in an anonymous manner. In addition, an anonymous batch authentication scheme is also proposed in this article to authenticate a batch of users in the subscription phase to alleviate the authentication burden of the HES. The security analysis section shows that the proposed scheme is more efficient in terms of security and the performance analysis section shows the strength of this article in terms of computational cost, while performing anonymous authentication in mobile pay‐TV systems.

基于IoT的移动付费电视系统的计算有效且安全的匿名认证方案

在未来几年中，移动付费电视系统由于其广泛的应用而将非常受欢迎。提供安全性和隐私是移动付费电视系统安全开发中最具挑战性的问题。为避免未经授权访问移动付费电视服务，以匿名方式对移动用户和前端系统（HES）进行身份验证非常重要。即使有人提出了几种身份验证方案来提供匿名身份验证，但先前提出的方案由于计算量大，因此不适合移动付费电视应用。因此，本文提出了一种计算有效的匿名认证方案，用于在移动付费电视系统中提供安全的服务。所提出的认证方案可以以匿名方式以较低的计算成本有效地认证移动用户和HES。此外，本文还提出了一种匿名批认证方案，以在订阅阶段对一批用户进行认证，以减轻HES的认证负担。安全分析部分表明，在安全性方面，所提出的方案更有效；性能分析部分，在计算成本方面展示了本文的优势，同时在移动付费电视系统中执行匿名身份验证。
