我们提出了云计算的数字版权管理(DRM)概念，并展示了如何以隐私友好的方式实现云中软件的许可证管理。在我们的场景中，从软件提供商那里购买软件的用户保持匿名。同时，我们的方法确保软件许可证与用户绑定，并在执行之前检查其有效性。我们采用了一种软件重新加密方案，这样执行用户软件的计算中心就不能建立他们用户的用户配置文件--甚至不能用化名。我们结合了秘密共享和同态加密。我们确保恶意用户无法将软件转发给他人。DRM激励软件提供商参与未来的云计算场景。我们通过保护用户的隐私使这一场景对用户更具吸引力。
We come up with a digital rights management (DRM) concept for cloud computing and show how license management for software within the cloud can be achieved in a privacy-friendly manner. In our scenario, users who buy software from software providers stay anonymous. At the same time, our approach guarantees that software licenses are bound to users and their validity is checked before execution. We employ a software re-encryption scheme so that computing centers which execute users' software are not able to build user profiles - not even under pseudonym - of their users. We combine secret sharing and homomorphic encryption. We make sure that malicious users are unable to relay software to others. DRM constitutes an incentive for software providers to take partin a future cloud computing scenario. We make this scenario more attractive for users by preserving their privacy.
