Platform Property Certificate For Property-Based Attestation Model

Trusted Computing Group (TCG) provides a group of prominent computer manufacturers to improve a new technology called Trusted Computing (TC) which can provide a basis to the highest security level in hardware and software.Remote attestation is one of the TC aspects which is the method that a system uses to authenticate to a remote party or for a remote party to verify the authenticity of the application.However, binary attestation mechanism still lacks in flexibility, privacy and scalability and to overcome these problems Property Based Attestation was introduced. Two important issues should be considered in this context: the content of the property and the protocol that we should choose.We proposed Platform Property Certificate based on the current certificates of a system (AIK and SSL certificates), in our study as the model's property. Performance evaluation method in this study is implementation with existing specification and hardware of TC and the criteria that are evaluated are privacy, flexibility and scalability that are compared in the proposed model with the TCG binary attestation model.
