Embodiment Construction

[0033] In order to facilitate the understanding of the embodiments of the present invention, several specific embodiments will be taken as examples for further explanation below in conjunction with the accompanying drawings, and each embodiment does not constitute a limitation to the embodiments of the present invention.

[0034] According to one aspect of the present invention, as figure 1 As shown, a method for constructing a database table for a time stamp server is provided, the method comprising: constructing a key table in the database, and setting an agent point field and a state value field in the key table, wherein: the key table It is used to record the processing status of the key. The proxy point field is used to record the detailed information of each proxy point and the processing of the key by each proxy point. The status value field is used to manage the key corresponding to each proxy point and its update, Condition of use.

[0035] In the actual operation pr...

Abstract

The invention relates to a database table construction method for a timestamp server; the method comprises the following steps that a secret key table is built in a database of the timestamp server; the secret key table is used for recording the processing condition of the secret key; a proxy point field and a state value field are set in the secret key table; the proxy point field is used for recording the detailed information of each proxy point and the condition that each proxy point processes the secret key; and the state value field is used for managing the secret keys corresponding to the proxy points and the updating and using conditions of the secret keys. According to the method, when the multi-proxy point uses the timestamp server at the same time, the certificate operation of each proxy point is more effective and convenient.

Description

technical field [0001] The invention relates to the field of time stamp servers, in particular to a database table construction method for the time stamp server. Background technique [0002] With the continuous development of information technology, electronic transactions continue to penetrate into our lives. The traditional public key infrastructure can guarantee the identity authentication between the two parties in the transaction, but it seems a bit powerless to ensure that the transaction documents are not tampered with and denied afterwards. If a reliable third-party time stamp authority (Time Stamp Authority, TSA) organization is relied on to provide time stamp services at this time, and a credible time stamp is added to the transaction, this problem can be solved. A trusted time stamp is an electronic certificate issued by an authoritative trusted time stamp service center that can prove that a data message (electronic file) exists, is complete, verifiable, and ha...
