随着移动产业的快速发展和壮大,出现了大量的移动应用和服务,其中涉及互联网规模的数据采集。同时,大量数字内容被盗版和非法传播,对数字内容提供商以及移动行业造成巨大影响。数字版权管理(DRM)旨在通过规范数字内容的使用来保护数字内容免遭滥用。不幸的是,据我们所知,这些 DRM 方案中很少有人关心当用户数量扩大时 DRM 系统中服务器的成本,并考虑可被视为内容服务器租户的内容提供商的利益。在本文中,我们提出了 CS-DRM,一种针对移动互联网的基于云的 SIM DRM 方案。 CS-DRM引入SIM卡,既降低了成本,又提供了更高的安全性。同时,云计算的特性使得CS-DRM能够为内容提供商带来收益,能够以低成本很好地满足用户数量大幅增长时的性能需求。此外,我们还实现了 DRM 方案的原型,这证明了 CS-DRM 的高效、安全和实用。
With the rapid development and growth of the mobile industry, a considerable amount of mobile applications and services are available, which involve Internet scale data collections. Meanwhile, it has a tremendous impact on digital content providers as well as the mobile industry that a large number of digital content have been pirated and illegally distributed. Digital Rights Management (DRM) aims at protecting digital contents from being abused through regulating their usage. Unfortunately, to the best of our knowledge, fewer of these DRM schemes are concerned with the cost of the servers in a DRM system when the number of users scales up, and consider benefits of content providers who can be seen as tenants of a content server. In this paper, we propose CS-DRM, a cloud-based SIM DRM scheme, for the mobile Internet. The SIM card is introduced into CS-DRM to both reduce the cost and provide higher security. Also, the characteristics of cloud computing enable CS-DRM to bring benefits for content providers, and well satisfy the performance requirements with low cost when the number of users increases significantly. Furthermore, we have implemented a prototype of our DRM scheme, which demonstrates that CS-DRM is efficient, secure, and practicable.
