Embodiment 1

[0040] Embodiment 1 of the present invention provides an electronic data storage system based on double asymmetric encryption technology, such as figure 1 As shown, it is a schematic structural diagram of an electronic data storage system based on double asymmetric encryption technology according to Embodiment 1 of the present invention, including a certification authority verification server 11, a certification authority time server 12 and a data storage server 13;

[0041] The verification server 11 of the certification agency can be used to receive the electronic data submitted by the parties, and verify the received electronic data, request the time stamp from the certification agency time server 12 in real time, and calculate the electronic data and the time stamp. The combined MD5 value of the stamp is used to fix the electronic data to ensure that the electronic data submitted by the parties has not been tampered with, and the fixed electronic data and the time stamp are...

Embodiment 2

[0066] Based on the same inventive concept as that of Embodiment 1 of the present invention, Embodiment 2 of the present invention provides a method for storing electronic data based on double asymmetric encryption technology. For the electronic data storage system of technology, the specific implementation of this method can refer to the relevant description in the above-mentioned system embodiment one, and the repetition will not be repeated. The method mainly includes:

[0067] Step A1: The verification server of the certification authority receives the electronic data submitted by the party and verifies the received electronic data;

[0068] Step A2: request the time stamp from the time server of the certification authority in real time, calculate the joint MD5 value of the electronic data and the time stamp, and fix the electronic data;

[0069] Step A3: Transmitting the fixed electronic data and the time stamp to the data storage server in real time.

[0070] Further, t...

Embodiment 3

[0073]Based on the same inventive concept as that of Embodiment 1 of the present invention, Embodiment 3 of the present invention provides an electronic data storage method based on double asymmetric encryption technology. For the electronic data storage system of technology, the specific implementation of this method can refer to the relevant description in the above-mentioned system embodiment one, and the repetition will not be repeated. The method mainly includes:

[0074] The time server of the certification institution is synchronized with the external reference clock, and provides time stamp services for the verification server of the certification institution to ensure the reliability of the system time.

[0075] Further, the time server of the certification authority performs time synchronization with the external reference clock through the NTP protocol, and the time is accurate to milliseconds.

[0076] Embodiment 3 of the present invention provides an electronic da...

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...
