Abstract: The different security levels of electronic signature technologies determine the difference of authenticity and reliability of signature evidences. The preconcept and rule of “reliability” should be introduced into the identification of the admissibility and probative force of signature evidences, and the examination should be separated from the authenticity.If the purported signatory wants to deny the signature on a message, he may need to prove that the signature is genuine but not authorized, or there is no intention of being legally bound, or the signature is false, or the digital certificate is invalid; Because of the trust relationship between the relying party and the certification authority, the relying party has the duty of diligence and prudence in the certification process and operation. The reliance of the relying party on a signature or certificate should be reasonable, and he should check and be able to prove that they checked.

Key words: electronic signature, the signatory, the relying party, burden of proof, reliability
