Authentication of trusted platform module using processor response

Abstract

Authentication is the process which allows both the communicating entities to validate each other. Authentication is the base for the trust between the two communicating party if both party wants to properly communicate. Trusted Platform Module (TPM) can be used to securely store artifacts like passwords, certificates, encryption keys or measurements required to authenticate the platform. In the present scenario there is no concrete mechanism to authenticate the TPM chip. In this project, a method has been proposed to enable user of a system to authenticate the TPM chip of the communicating system. The proposed system uses public endorsement key of the TPM chip and the unique response the processor gives while executing a program with predefined set of step delays.
