A Signature System Based on Trust Computing

The E-signature is usually forged by malice code in environment of common PC at present, so the anthenticity of the E-signature is hard to be guaranteed. A solution of embedded trusted E-signature system is proposed in this paper. The system designs a Trusted E-signature Terminal basing on Trusted Platform Module (TPM), and constructs a trusted E-signature environment by establishing trusted chain in the terminal. The system signs the file that show on the LCD of the terminal,so the signature is trusted because it realizes the fuction of what you see is what you sign.
