Abstract: In this paper, in order to solve the safety problems of electronic signature in the electronic document, a protection system of electronic document was constructed based on trusted cryptography module (TCM) combined with the combined public key (CPK). A scheme of signing and verifying under trusted computing environment was designed. And as an example, the realization process of the scheme based on Word document level programming was elaborated for the Office Word.
Key words: data security and computer security; trusted cryptography module; combined public key; electronic signature
