Proxy Re-encryption in a Privacy-Preserving Cloud Computing DRM Scheme

  • Ronald Petrlic
Part of the Lecture Notes in Computer Science book series (LNCS, volume 7672)


In a cloud-computing scenario where users buy software from software providers and execute it at computing centers, a digital rights management (DRM) system has to be in place to check the software licenses during each software execution. However, the exposure of users to privacy invasion in the presence of DRM systems is problematic.

We come up with a concept that unites software providers’ and users’ demands for a secure and privacy-preserving DRM system for cloud computing. The employment of proxy re-encryption allows for a prevention of profile building (under pseudonym) of users by any party.
