Electronic data safekeeping system and method based on double and asymmetric encryption technology

Abstract

The invention discloses an electronic data safekeeping system and method based on the double and asymmetric encryption technology. The system has the advantages that all electronic data submitted by a party involved is stored in a server of a certifying institution, and the certification institution participates throughout encryption and decryption processes for the electronic data, so that tampering of the data during storage can be prevented; the electronic data submitted by the party involved is fixed through verification of an MD5 value and a timestamp, so that completeness of the original data can be ensured, and tampering of the original data can be prevented; and through the double and asymmetric key encryption technology, when the party involved applies for a certification, the party involved and the certifying institution need to successively carry out double decryption of the encrypted original data through private keys, the original data needs to be obtained, and the MD5 value and the timestamp need to be verified, so that the data can be prevented from being tampered or denied, the completeness and confidentiality of the data can be ensured, and the rights and interests of the certifying institution and the party involved can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to an electronic data storage system and method based on double asymmetric encryption technology. Background technique [0002] With the rapid development of computer technology and computer network, the application of computer network has penetrated into all walks of life, and it has also brought opportunities and new challenges to relevant certification agencies. Through the Internet platform, the means, methods and procedures of traditional certification agencies have been changed, but the nature of its certification rights in legal facts and legal acts has not changed. It is an extension of traditional certification rights in the network field. The certified electronic data is no longer limited to paper data in the traditional sense, and electronic data informatization extends the connotation of traditional data. In the era of Internet technology, disputes involvin...

Problems solved by technology

[0011] The embodiment of the present invention provides an electronic data storage system and method based on double asymmetric encryption technology, which is used to solve the problem that in the prior art, the certification agency cannot guarantee that the electronic data obtained from the third-party platform has not been tampered with and publicly certify the electronic data. After that, there is no guarantee that the electronic data after the public certification has not been tampered with
