Block chain private key management method and system based on elliptic curve offset, and storage medium

Abstract

The invention relates to the technical field of block chains, in particular to a block chain private key management method and system based on elliptic curve offset and a storage medium. The method comprises the following steps: generating a seed private key and a seed public key corresponding to the seed private key; obtaining an offset; obtaining a new public key from an elliptic curve accordingto the seed public key and the offset; calculating to obtain a new wallet address according to the new public key; and obtaining a new private key from the elliptic curve according to the seed private key and the offset, and signing the transaction of the new wallet address by using the new private key. According to the method, generation of the private key of the wallet address depends on the seed private key and the offset, and leakage of the private key of the wallet address cannot be caused by independent leakage of the seed private key and the offset, so that the safety of the wallet isgreatly improved, and meanwhile, the problem that a common wallet needs to create a public and private key pair for each address for storage and backup is avoided.

Description

technical field [0001] The present application relates to the technical field of blockchain, in particular to a blockchain private key management method, system and storage medium based on elliptic curve offset. Background technique [0002] Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Blockchain technology can be understood as distributed ledger technology, which is an Internet database technology, which is characterized by decentralization, openness and transparency, allowing everyone to participate in database records. [0003] In the underlying technology of the blockchain, a series of cryptographic methods are used to ensure the security of data and the reliability of transactions, including the use of the one-way characteristic of the asymmetric elliptic curve encryption algorithm to generate public-private key pairs. Among them, the private ...

AI Technical Summary

Problems solved by technology

The main problem of this method is: every time a private key is regenerated, it means that with the increase of the number of users, more and more private keys need to be stored, and the private key is difficult to manage, backup and import

Although the deterministic wallet simplifies the backup and recovery method of the private key, once the seed or mnemonic is leaked, the account funds corresponding to all private keys are at risk of being stolen
