“…DRM refers to restrictions associated with specific instances of digital works or devices rather than to other forms of copy protection, such as serial numbers or keyfiles, that can be circumvented without modifying the files or devices. In recent years, there have been many research efforts and publications related to DRM [4][5][6][7][8][9][10][11][12].…”

Digital rights management (DRM) is a term for access control technologies that are used by hardware manufacturers, publishers, copyright holders, and individuals to limit the use of digital content and devices. Enterprise digital rights management (E‐DRM) is the application of DRM technology to prevent illegal users from accessing the confidential data of an enterprise. In 2010, Chang et al. proposed an efficient E‐DRM scheme to solve the flaws of Chen's scheme. However, we still found some weaknesses in their scheme. In this article, we propose an improved secure and efficient E‐DRM mechanism based on a one‐way hash function and exclusive‐or. Our mechanism overcomes the weaknesses in the scheme of Chang et al. and also reduces computation costs. In addition, we used BAN logic to show the correctness of our mechanism.

Digital rights management (DRM) system is a technology based mechanism to ensure only authorized access and legal distribution/consumption of the protected digital content. DRM system deals with the whole lifecycle of the digital content including production, management, distribution and consumption. DRM schemes are effective means for the transfer of digital content and safeguard the intellectual property. Recently, Yang et al. proposed a smart-card based DRM authentication scheme providing mutual authentication and session key establishment among all the participants of the DRM environment. We show that their scheme does not resist threats like smart card attack; fails to provide proper password update facility; and does not follow forward secrecy. To overcome these weaknesses, we propose an improvement of Yang et al.'s scheme. The security of our scheme remains intact even if the smart card of the user is lost. In our scheme, user's smart card is capable of verifying the correctness of the inputted identity and password and hence contributes to achieve an efficient and user-friendly password update phase. In addition, the session keys established between the participating entities are highly secure by virtue of forward secrecy property. We conduct security analysis and comparison with related schemes to evaluate our improved scheme. During comparison, we also highlight the computational cost/time complexity at the user and the server side in terms of the execution time of various operations. The entire analysis shows that the design of the improved scheme is robust enough for the for DRM environment.
