       Privacy Enabled Digital Rights Management Without Trusted
                        Third Party Assumption
   Abstract
          Digital rights management systems are required to provide security and
   accountability without violating the privacy of the entities involved. However,
   achieving privacy along with accountability in the same framework is hard as these
   attributes are mutually contradictory. Thus, most of the current digital rights
   management systems rely on trusted third parties to provide privacy to the entities
   involved. However, a trusted third party can become malicious and break the
   privacy protection of the entities in the system. Hence, in this paper, we propose a
   novel privacy preserving content distribution mechanism for digital rights
   management without relying on the trusted third party assumption. We use simple
   primitives such as blind decryption and one way hash chain to avoid the trusted
   third party assumption. We prove that our scheme is not prone to the “oracle
   problem” of the blind decryption mechanism. The proposed mechanism supports
   access control without degrading user's privacy as well as allows revocation of
   even malicious users without violating their privacy.

Impulse Technologies Beacons U to World of technology 044-42133143, 98401 03301,9841091117 ieeeprojects@yahoo.com www.impulse.net.in Privacy Enabled Digital Rights Management Without Trusted Third Party Assumption Abstract Digital rights management systems are required to provide security and accountability without violating the privacy of the entities involved. However, achieving privacy along with accountability in the same framework is hard as these attributes are mutually contradictory. Thus, most of the current digital rights management systems rely on trusted third parties to provide privacy to the entities involved. However, a trusted third party can become malicious and break the privacy protection of the entities in the system. Hence, in this paper, we propose a novel privacy preserving content distribution mechanism for digital rights management without relying on the trusted third party assumption. We use simple primitives such as blind decryption and one way hash chain to avoid the trusted third party assumption. We prove that our scheme is not prone to the “oracle problem” of the blind decryption mechanism. The proposed mechanism supports access control without degrading user's privacy as well as allows revocation of even malicious users without violating their privacy.
