Embodiment Construction

[0046] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0047]It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illu...

Abstract

The invention discloses an SM9-based blockchain node admission verification method and system. The system comprises an SM9 key generation module, a key distribution module, an information storage module, a service module, a processing module, an initialization verification module, a password service module and a blockchain identity verification module. A secret key is generated for the blockchainnode through the SM9 secret key generation module, so that the complex process of secret key management of the PKI / CA certificate system is simplified; the key distribution module is arranged to provide an identifier-based public key for the blockchain node, so that the operations of analyzing a certificate and verifying the validity of the certificate and a certificate chain in a PKI / CA certificate system are omitted, and the node verification time of the blockchain is shortened; according to the blockchain node admission verification method, the identity structure and process of the admitterare simplified, and the overall efficiency of initialization of the blockchain node and addition of the new node to the blockchain network is improved.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to an SM9-based block chain node access verification method and system. Background technique [0002] In the commercial encryption system, SM9 is mainly used for user identity authentication. However, in the current blockchain platform, most of the blockchain platforms adopt PKI / CA-based identity access verification mechanism, but there are the following problems in adopting PKI / CA-based identity access verification mechanism: [0003] 1. Due to the complex communication process and cumbersome key management process in the PKI / CA certificate system, the complexity of blockchain node access is too high; [0004] 2. The identity access verification mechanism based on the PKI / CA certificate system needs to verify the validity of a large number of certificates and certificate chains, thereby prolonging the time for blockchain nodes to verify access; [0005] 3. The blockc...
