A novel identicication scheme for post-quantum secure digital right management

With the progress of technology and widespread use of internet, the data has become digital. It is getting easier day by day to copy, modify and transform digital data / applications into another form. The term of digital rights management (DRM) has been suggested to limit the use of data in digital media and to protect copyrights. Different architectures / technologies are used to provide DRM. In existing architectures, the user is unaware whether the license, which was purchased, is used by an unauthorized party. In this paper, a structure is given to resolve this problem and fairness property is added for DRM architectures. Moreover, a post-quantum reliable identification protocol based on multivariate quadratic systems, which can be used for access control in DRM architecture, is proposed.
