Embodiment 1

[0050] This embodiment provides a processing flow of a distributed timestamp processing method such as figure 1 As shown, in this embodiment, a first server is provided, and the first server performs the following operations: S11. When issuing a timestamp, send the file abstract matching the file identifier to the peer server; wherein, the peer server Process and obtain the first hash timestamp;

[0051] First, the application server receives the file submitted by the client;

[0052] The application server matches the files and the identifiers corresponding to each file and then distributes them to each node of the local server; each node of the local server receives the distributed files; before sending the file summary matching the file identifier to the peer server ,include:

[0053] When the time stamp is issued, the allocated files are received, wherein each file has a one-to-one identifier, the file summary is obtained, and the matching file identifier is matched with...

Embodiment 2

[0062] This embodiment provides a processing flow of a distributed timestamp processing method such as figure 2 As shown, in this embodiment, a second server is provided, and the following operations are performed on the second server:

[0063] S13. When the time stamp is issued, receive the file digest that matches the file identifier, and process the file digest that matches the file identifier to obtain a first hash timestamp, generate a first signature from the first hash timestamp and Issuing; wherein, the file abstract matching the file identifier is sent by the peer server;

[0064] The processing the file abstract matched with the file identifier to obtain a first hash timestamp, generating and signing a first signature from the first hash timestamp includes:

[0065] When the time stamp is issued, the received file abstract matching the file identifier and the first current time are hashed to obtain the first hash time stamp, and the first hash time stamp is encrypt...

Embodiment 3

[0073] This embodiment provides a processing flow of a distributed timestamp processing method such as image 3 As shown, in this embodiment, a first server and a second server are provided. In this embodiment, the Mapper server is used as the first server, and the Reducer server is used as the second server;

[0074] as attached Figure 4 As shown, the first server and the second server perform the following operations respectively:

[0075] Perform the following operations on the first server:

[0076] S11. When the time stamp is issued, send the file abstract matching the file identifier to the peer server; wherein, the peer server processes and obtains the first hash time stamp;

[0077] First, the application server receives the file submitted by the client;

[0078] The application server matches the files and the identifiers corresponding to each file and then distributes them to each node of the local server; each node of the local server receives the distributed fi...

Abstract

The embodiment of the invention provides a processing method, server and system for a distributed timestamp. The processing method includes the steps that when a timestamp is signed and issued, a file summary matched with a file identification is sent to an opposite terminal server; the opposite terminal server obtains a first Hash timestamp; when the timestamp is identified, a to-be-verified file is processed, a second Hash timestamp is obtained, the second Hash timestamp is encrypted to obtain a second signature, and the second signature matched with the to-be-verified file is sent to the opposite terminal server; the opposite terminal server decodes and obtains the second Hash timestamp, and when the first Hash timestamp and the second Hash timestamp are same, verification is passed. By means of the processing method, the user requirements with the huge number can be met, the response efficiency of the system is improved through concurrent processing, and the processing method has the good expansibility; the time consistency of the distributed server is guaranteed through offset correction.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a processing method, server and system of a distributed time stamp. Background technique [0002] The trusted time stamp is issued by the authoritative time agency (TSA) to certify the generation time of the electronic document for timing protection. It is used to solve the proof of the existence and content integrity of the data message, and it is the legal validity proof that the content of the data message has not been tampered with or forged. Trusted timestamps have the characteristics of easy verification, non-repudiation, and confidentiality by ensuring the integrity of the content and the point of existence, and are mostly used for electronic certificates such as electronic signatures. Using data digest and digital signature means to stamp digital time stamp, the time stamp protocol is mainly in an intuitive way, a linear link mechanism, and a tree mechanism....
