Description
Technical Field
A license block chaining system based on-chain Hash state management specifically belongs to the technical field of block chains.
Background
In the main process of the existing electronic certificate block chaining scheme, after certificate authority fills certificate name, serial number, owner, validity period and other certificate face information in a centralized platform, certificate information is encrypted and uploaded to a certificate chain through on-chain exchange, wherein the certificate chain, the certificate name and the serial number form retrieval information and are uploaded to another retrieval chain or an off-chain database, and the database stores a piece of data of the owner and the retrieval information so as to facilitate retrieval of all certificates of a holder.
The licensee can inquire the retrieval information of the required license through a database of the platform, the retrieval information comprises the block on the chain and the index of the transaction, and the licensee can acquire the license data of the licensee, namely all the license data are encrypted and linked.
When the third party verifies, the data or the two-dimensional code encrypted by the licensee needs to be scanned, and the third party can verify the data or the two-dimensional code after being requested by the licensee.
The second mode of the block chain certificate can verify the certificate mode, only the data identity is verified to be chained, and the certificate issuer encrypts and signs the data through the offline, and the verification modes are two, depending on whether the certificate can be directly acquired by the certificate issuer, if the certificate can be directly acquired by the certificate issuer, the certificate can be directly signed by the certificate issuer after the identity of the certificate issuer and the certificate holder is verified, and if the certificate cannot be directly acquired by the certificate issuer, the certificate issuer can initiate a request to the user data hosting platform, and after the user authorization is acquired, the certificate information can be checked and verified.
Firstly, in most current schemes of certificates, the whole data of the certificates are required to be encrypted and linked, so that the certificates are inevitably required to be encrypted by a certificate issuing and certifying party, namely the certificate issuing and certifying party is used as a necessary link for issuing and managing the certificates, the purpose and the process of issuing part of the certificates are not consistent, the certificates in the general sense are certification documents issued to a specific main body by an authority, the issuing and the logout of the certificates are mainly controlled by the authority according to the certificate issuing and managing principles, and the participation of the certificate issuing party in different certificates is different in sufficiency and necessity, so that the decryption and the authorization of the certificate issuing party are only related to the privacy protection of the certificate issuing party and the logout of the certificates, and the privacy protection and the certificate issuing can be independent into two different subsystems. If the identity signature of the licence is introduced in the license issuing link, the difficulties of verification and license management, re-issuing and changing are increased, and all licenses need to be issued again under the condition that the identity key of the issuer or the licence is changed when the license information is changed. In the current CA certificate issuing method in China, the CA certificate is expired and replaced regularly, besides, the management key of the certificate issuing party or the certificate holding party is replaced regularly based on a safe key management system or method, and if all certificates are issued once again at the moment, the time cost and the economic cost are very high
And secondly, in most cases, the certification authority needs to be obtained for certification when the certification authority verifies, and the method is more suitable for a mode that the certification authority needs to be obtained through the user data hosting platform. However, for a mode that a third-party user does not need to submit a certificate, when a certificate holder submits the certificate to a certificate user, the certificate information is obtained, and then only the identity of an issuer and the identity of the certificate holder need to be verified, and the mode is also a mode for using the certificate in daily life.
