Digital signature and signature authenticating method

Abstract

The invention provides a digital signature and a signature authenticating method which comprises the following steps: step 102, receiving business documents; step 104, reading the signature rule contract corresponding to the business documents; step 106, according to the signature rule contract corresponding to the business documents, resolving the document fields from the business documents and forming a plain text of signature; step 108, after a sender digitally signs on the plain text of signature, sending the business document to a receiver; and step 110, receiving the business documents by the receiver and authenticating the signature. The invention also provides a digital signature and a signature authenticating device. According to the invention, a user can dynamically configure the field rules of 'signature / signature authentication', relative independence of business demands and an authentication function is realized, and a uniform log record for the authenticating operation is provided, thus ensuring that all signature records can be looked up with a basis.

Description

technical field [0001] The invention relates to security authentication technology, in particular to a digital signature and a signature verification method. Background technique [0002] CA security authentication technology provides an important technical guarantee for verifying and identifying the authenticity of electronic documents (especially involving financial transactions), which can prevent major accidents caused by malicious damage by others, and can also hold relevant responsible persons accountable. However, there are some defects and deficiencies in the application of CA security authentication technology in various application systems at present. [0003] Due to the defects and deficiencies of current CA professional providers, only atomic signature / signature verification APIs are provided, which cannot simplify the application in business. The content rules of "signature / signature verification" cannot be dynamically configured according to the customer's bus...

AI Technical Summary

Problems solved by technology

There is no unified standard processing method for the storage of signed document ciphertext. Most business documents are processed by naming a column in the document table for storage. Another problem with this is that the signatures of all the persons in charge of the document cannot be traced record, only the latest signature ciphertext can be remembered
