Abstract

An embodiment of the invention discloses a private key storage and reading method and device and a hardware device. According to the private key storage and reading method and device and the hardwaredevice, confusion is carried out on sensitive data comprising private key and the like according to universal unique identification code of the hardware device and user passwords and the like to obtain matrix data for storage and reading; according to the scheme, confusion is only carried out in the aspect of data storage, so that computation amount is small; data is not encrypted, so that users can integrate any encryption algorithm based on the scheme to enhance protection of the private key; and the scheme is not limited by the data structure, can be applied to private key storage of various currencies, and is high in university.

Description

technical field [0001] The present application relates to the technical field of information security, in particular to a private key storage and reading method, device and hardware equipment. Background technique [0002] The concept of Bitcoin was first proposed by Satoshi Nakamoto in 2009, and it is a digital currency based on a P2P network. Blockchain is an important concept associated with Bitcoin. In a narrow sense, the blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be tamper-proof and unforgeable distributed ledgers. Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses automated scripts to A new distributed infrastructure and computing method for programming and mani...
