Abstract

Digital Rights Management (DRM) is a popular approach for secure content distribution. Typically, DRM encrypts the content before delivers it. Most DRM applications use secure algorithms to protect content. However, executing these algorithms in an insecure environment may allow adversaries to compromise the system and obtain the key. To withstand such attack, algorithm implementation is modified in such a way to make the implementation unintelligible, namely obfuscation approach. White-box cryptography (WBC) is an obfuscation technique intended to protect secret keys from being disclosed in a software implementation using a fully transparent methodology. This mechanism is appropriate for DRM applications and able to enhance security for the content provider. However, DRM is required to provide a balanced protection for the content provider and users. We construct a protocol on implementing WBC to improve DRM system. The system does not only provide security for the content provider but also preserves privacy for users.
