Abstract

The invention discloses a method and system for achieving electronic signature. According to the method, the distributed summary computing method is adopted, summary computing is achieved through distributed computing of the client side and distributed computing of the server side, an intermediate result and remainder data of the summary are obtained through primary summary computing by means of the client side and then are sent to the server side, then summary computing of the remainder part is achieved by means of the client side according to the summary computing of the client side to obtain a summary result, digital signature is conducted on the summary result to obtain a signature object which is sent to the client side together with a seal object, and finally the signature object and the seal object are added to a file to be signed through the client side so that signature can be achieved and a signed file can be obtained. The method and system have the advantages of being low in cost, high in efficiency and high in data safety.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method and system for realizing electronic signature. Background technique [0002] Electronic signature technology is a specific application of digital authentication technology. It is used as a means of identity verification. It generally refers to all electronic documents that exist in electronic form, attached to electronic documents and logically associated with them, and used to identify the identity of the electronic document signer. Guarantees the integrity of the document and signifies that the signer agrees with the content of the facts stated in the electronic document. Electronic signature is a form of expression of electronic signature. It uses image processing technology to convert electronic signature operation into the same visual effect as paper document sealing operation, and uses electronic signature technology to ensure the authenticity and integri...
