Abstract:
Digital Rights Management(DRM)is a technology to protect digital contents from illegal usages after sale.DRM depends on soft cryptography protection,which is a weak protection against hackers.Trusted DRM applied TPM security chip to improve protection in terms of hardware for authentication,licensing and other aspects.To overcome the problem of user privacy,trusted DRM used direct anonymous authentication protocol.On this basis,this article proposed an improved protocol based on zero-knowledge proof and ElGamal signature algorithm of double random numbers,and then described its application in trusted DRM.The proposed technique could improve security and anonymity in DRM.
