This research studies the problem of digital content distribution in conjunction with the effective enforcement of intellectual property rights and laws from a cryptographic viewpoint. Understanding, modeling and constructing the necessary framework and tools for digital content distribution and rights enforcement are fundamental for the development of future Digital Rights Management (DRM) systems. Cryptography is a technology that, if applied correctly, has a recognized potential in minimizing trust assumptions, alleviating production and distribution costs, facilitating legal frameworks as well as mitigating threats in the context of DRM systems. The methodological viewpoint of the present research is to harvest the techniques of modern cryptography for the specification and solution of various facets of the DRM problem and advance the understanding of what cryptography can offer to future DRM technologies. The present investigation provides a framework for modeling digital content distribution systems together with the arrays of adversarial behaviors against them and delves into the development of novel cryptographic constructions finely tuned to DRM environments. Various cryptographic tools for DRM systems are investigated, their interoperability and composition within a digital content distribution system are studied and their threat mitigation capabilities as well as interactions with legal frameworks are examined.

本研究从密码学的观点，结合知识产权和法律的有效执行，研究数字内容分发的问题。理解、建模和构建数字内容分发和版权强制执行的必要框架和工具是未来数字版权管理（DRM）系统开发的基础。密码学是一种技术，如果正确应用，在最大限度地减少信任假设，降低生产和分销成本，促进法律的框架以及减轻DRM系统的威胁方面具有公认的潜力。本研究的方法论观点是收获现代密码学技术的规范和解决DRM问题的各个方面，并推进什么密码学可以提供给未来的DRM技术的理解。目前的调查提供了一个框架，用于建模数字内容分发系统与阵列的对抗性行为对他们和深入到新的加密结构的发展微调到DRM环境。DRM系统的各种加密工具进行了调查，他们的互操作性和数字内容分发系统内的组成进行了研究，他们的威胁缓解能力，以及与法律的框架的相互作用进行了检查。
