Abstract

The invention relates to a QKD network authentication key generation method and system based on an alliance chain and an implicit certificate. The method is implemented among alliance chain members communicating with each other. The alliance chain members comprise client members and server members; it is characterized in that each member is configured with a key fob; a server public key pool, a server secret sharing private key pool and a client public key pool are stored in the server secret key card; client private keys, private key parameters, server public keys and client public key pointer random numbers are stored in the client secret key cards, and the server public keys comprise a first public key and a second public key; public key units in one-to-one correspondence with the client members are stored in the client public key pool, and identity identifiers and implicit certificates are stored in the public key units. During communication of each party, encryption communicationis carried out by using the key fob based on the alliance chain and the implicit certificate, so that the security is further improved.

Description

technical field [0001] The present application relates to the field of consortium chains, in particular to a method and system for generating QKD network authentication keys based on consortium chains and implicit certificates. Background technique [0002] Blockchain is a brand-new distributed infrastructure and computing paradigm. It uses an orderly chained data structure to store data, uses consensus algorithms to update data, and uses cryptography to ensure data security. In blockchain-based transactions, ensuring the data security of transactions and the privacy of customers is a necessary condition for the further development of blockchain. For this reason, cryptography, especially public key cryptography, has been widely used in blockchain. The alliance chain is a branch of the blockchain, so it is also a distributed and decentralized public database. The difference from other chains is that it is aimed at members of specific groups and limited third parties. Each p...
