Problems solved by technology

[0005] (1) The probability of the key being illegally stolen is high
[0006] (2) The key is stolen by the attacker, and the attacker will obtain the user's private information
[0007] (3) The efficiency and security of key recovery, generation, distribution and update are not high
[0008] (4) There are many direct human interventions in key management
There is very little work in this field, and there is no better key management solution to manage the keys in the existing blockchain

Abstract

The invention discloses a block chain key hierarchical management method, and relates to the technical field of data encryption management methods. The method comprises the following steps: initializing a user password, a login certificate, a password secret key, a main secret key and a main secret key ciphertext in a block chain system; generating a user private key, a user public key, a key fileand a user private key ciphertext; performing hierarchical management on the file encryption key, the file, the file ciphertext, the file encryption key ciphertext and the uploaded file; sharing corresponding files, and completing block chain key hierarchical management. According to the method, the key management efficiency can be improved, and the security of all keys is ensured. Meanwhile, anattacker cannot tamper the secret key, and the probability that the secret key is illegally stolen is low. In the transmission and storage process, even if the secret key is embezzled by an attacker,the attacker cannot obtain valuable information.

Description

technical field [0001] The present invention relates to the technical field of data encryption management methods, in particular to a layered management method for blockchain keys. Background technique [0002] Blockchain was originally referenced in Bitcoin and is the underlying technology of Bitcoin. Blockchain is essentially a distributed database integrated with various computer technologies such as point-to-point network, consensus mechanism, encryption algorithm, smart contract, digital signature and hash chain. It is precisely because of the use of these technologies in the blockchain that it has the characteristics of decentralization, non-repudiation, and traceability. In this way, Bitcoin can be freely circulated on the Internet and the value migration in the untrusted network can be realized. By designing various smart contracts based on the blockchain, the blockchain can be applied to various fields, such as healthcare, financial technology, computing, auditing...
