The growing demand for digital content using smart devices has taken the attenuation towards the enforcement of rights in digital content distribution. Digital rights management (DRM) systems support copyrights and try to control the access of digital content in a user-friendly way. However, user-friendly systems should also support user’s rights along with system requirements. The portable DRM architecture has the potential to support user’s rights. One of the critical challenges in portable DRM systems is the anonymous and secure delivery of digital content. To address this issue, a smart card-based content distribution framework is presented, which supports mutual authentication and secure session establishment. The security proof of the proposed scheme is presented in a random oracle model with rigorous informal security analysis, which signals that the proposed scheme has desirable attributes of security. Moreover, the security analysis is also performed using a widely adopted simulation tool, namely, “Automated Validation of Internet Security Protocol and Application (AVISPA)”. The study of performance has been conducted, which signals that the proposed scheme is also addressing the requirements of efficiency.

对使用智能设备的数字内容日益增长的需求已经削弱了数字内容分发中的权利执行。数字版权管理 (DRM) 系统支持版权并尝试以用户友好的方式控制数字内容的访问。然而，用户友好的系统还应该支持用户的权利以及系统要求。便携式 DRM 架构具有支持用户权限的潜力。便携式 DRM 系统的关键挑战之一是数字内容的匿名和安全交付。为了解决这个问题，提出了一种基于智能卡的内容分发框架，它支持相互认证和安全会话建立。所提出方案的安全证明以具有严格非正式安全分析的随机预言机模型呈现，表明提议的方案具有理想的安全属性。此外，还使用广泛采用的模拟工具进行安全分析，即“互联网安全协议和应用程序的自动验证（AVISPA）”。已经进行了性能研究，这表明所提出的方案也解决了效率要求。
