Remote Attestation System in Trusted Computing

A safe and efficient component-level property attestation system is proposed.The program uses a variety of signature to ensure the authenticity and exactitude of each component's property attestation process and utilize the virtu al sub-group signature to achieve the privacy of the user platform.And compare d to existing remote attestation system,the program imports blind signature which can recover the message to reduce risk of attack on Certificate Authorization and to improve the sec urity of remote attestation system.The sub-group has a higher efficiency than the exi sting program which widely uses zero-knowledge signature.
