Anti-quantum computing anonymous identification method and system based on implicit certificate

Abstract

The present application relates to an anonymous identification method and system based on implicit certificates against quantum computing. Through the implementation between the members of the alliance chain that communicate with each other, the members of the alliance chain include client members and server members, all parties are equipped with key cards, and all key cards store algorithm parameters and server public key pools ; The key card of the server stores a server secret shared private key pool and a client public key pool, and the client public key pool stores a client unit corresponding to each client one by one, and the client unit is stored in the client public key pool. The client unit includes the user name, real identity, public key update status, implicit certificate and false identity of the corresponding client; the key card of the client is stored with the random number of the client public key pointer, the client private key And the private key parameter does not disclose one's own real identity in the message sent by User, but discloses one's own false identity, which further improves the security of the interaction between all parties.

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 identity identification based on 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. A pre-sele...

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
