Abstract

The application provides an electronic signature method. The method comprises the following steps: performing identity authentication, and if the identity authentication is passed, performing the following steps: acquiring compressed data for signing, wherein original data of the compressed data for signing include input electronic signature data and an electronic document needing to be signed; performing a signing operation on the compressed data for signing with a specified private key to obtain a signed document; and transmitting the signed document. Through adoption of the method, signing of the electronic document is finished; the security of the signing operation is ensured; and meanwhile a signing behavior is initiated by a signer.

Description

Technical field [0001] This application relates to the field of smart IC cards, in particular to an electronic signature method and device. Background technique [0002] The traditional signature is to sign the name on a paper document to represent the authorization and recognition of the signatory, which is needed everywhere in daily work and life. [0003] However, this traditional signature method is often subject to geographical and time constraints, which greatly compromises the convenience and efficiency of the signature, and also restricts the business exchanges and authorization of the signing parties. [0004] With the continuous development of electronic technology, the signature mode of electronic documents has come into people’s sight. By signing electronic documents, it represents the authorization and recognition of the signatory. It is not limited by time and region. It is convenient and efficient. However, how Ensuring the security of the signature is the primary iss...
