Problems solved by technology

[0003] For the method of relying on the system platform or blockchain nodes to store digital signatures to solidify data messages, in the subsequent judicial evidence collection process, multiple parties such as third-party platforms are required to participate in the verification. The verification process is cumbersome, the process and time are long, and related additional cost

Abstract

The invention provides an evidence storage method for solidifying a data message by using a digital certificate. The evidence storage method for the data message comprises the following steps; 1, evidence collection: a user calculates a HASH abstract value of an original data message locally by using a cryptographic SM3 algorithm; 2, certificate application: the user generates an SM2 asymmetric public and private keys, and uses the SM2 asymmetric public and private keys to encrypt the abstract value to obtain an encrypted value to generate a certificate request; step 3, certificate issuing: aCA mechanism takes the encrypted value of the data message abstract value as a digital certificate and writes the digital certificate into a user digital certificate in an extended manner; and s 4, evidence verification: the user saves the digital certificate. According to the method, a one-time pad scene certificate is adopted to simplify a certificate application integration mode, signature datadoes not need to be additionally hosted and stored, certificate integration is simple, and certificate usability and experience are good.

Description

technical field [0001] The invention relates to the technical encryption field of data texts, in particular to a certificate storage method using digital certificates to solidify data texts. Background technique [0002] At present, most methods of curing data messages use digital signatures, time stamps, electronic signatures or blockchain technology to protect the message digests of data messages. The data message obligee first applies for a digital certificate, and then digitally signs the data message. , the signature value is stored in the system platform or the blockchain node, so that the subsequent disputes can be obtained through the third-party platform to achieve the authenticity of the data message and the purpose of anti-tampering. [0003] For the method of relying on the system platform or blockchain nodes to store digital signatures to solidify data messages, in the subsequent judicial evidence collection process, multiple parties such as third-party platform...
