In the DRM environment, content is usually distributed in an encrypted form. Typically, a secure encryption algorithm is utilized to accomplish such protection. However, executing this algorithm in an insecure environment may allow adversaries to compromise the system and obtain information about the decryption key. Keeping such a key secret is a major challenge for content distribution systems. We consider two solutions for securing content delivery. The first solution involves modifying the algorithm in such a way as to make implementation unintelligible. The second solution involves setting a buyer-seller protocol to communicate the key securely. In addition, the protocol can be set to achieve security for the content provider and privacy protection for user. This paper describes a study of these scenarios for DRM applications w.r.t securing content delivery.
