Anti-quantum computing anonymous identity recognition method and system based on alliance chain and implicit certificate

Abstract

The invention relates to an anti-quantum computing anonymous identity recognition 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 include client members and server members, each party is configured with a key fob, and algorithm parameters and a server public key pool are stored in all the key fobs; a secret key card of the server stores a server secret sharing private key pool and a client public key pool. Client units in one-to-one correspondence with theclients are stored in the client public key pool, and each client unit comprises a user name, a true identity identifier, a public key updating state, an implicit certificate and a false identity identifier of the corresponding client; a client public key pointer random number, a client private key and a private key parameter are stored in a secret key card of the client, a message sent by a Userdoes not disclose an own real identity identifier, and a false identity identifier of the own is disclosed, so that the security of interaction of all parties is further improved.

Description

technical field [0001] This application relates to the field of consortium chains, in particular to a method and system for anti-quantum computing anonymous identification based on consortium chains and implicit certificates. Background technique [0002] Blockchain is a brand-new distributed infrastructure and computing paradigm. It uses an ordered 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 technology, 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...

Problems solved by technology

If lost, it may cause ID information leakage

If the ID is recorded at multiple identification devices, ID tracking can be realized, which is a serious information leakage in some application scenarios

[0005] 2. Identity recognition needs to be recognized by the identity recognition server, and the identity recognition server is at a higher risk of being attacked by DOS

If the communication and storage data are obtained by the enemy, the enemy can realize ID tracking, which is a serious information leakage in some application scenarios
