Private key storage method and device, computer equipment and storage medium

Abstract

The invention provides a private key storage method and device, computer equipment and a storage medium, and the storage method comprises the following steps: fragmenting a private key, and partitioning a memory, the fragment size being the same as the partition size; calculating a Hash value of the private key, encoding the Hash value according to a section, and determining an initial position ofthe private key fragment when the private key fragment is stored in a corresponding sub-partition of the first storage partition according to the section code; storing the data of the private key into the corresponding sub-partition of the first storage partition in an annular manner according to the initial position; jumping, picking up and dispersedly storing the data in the first storage subarea into a corresponding second storage subarea at a preset interval number; and performing data tampering on the first storage partition so as to invalidate the data of the first storage partition. According to the storage method, through scattered storage of the private key, the secure storage of the private key can be conveniently realized without adding an additional hardware device, and the possibility that the private key is violently cracked is reduced.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a private key storage method, a private key storage device, a computer device and a non-transitory computer-readable storage medium. Background technique [0002] With the development of network-related industries, the problem of network communication security has become increasingly prominent. The International Organization for Standardization has formulated some standards and methods to ensure communication security. Among them, the asymmetric encryption method is a method widely used in network communication security. Asymmetric encryption algorithm Two keys are required for encryption and decryption, and these two keys are a public key (Public Key, referred to as a public key) and a private key (Private Key, referred to as a private key). Regardless of whether it is a PC terminal device or an embedded device or some specific symmetric encryption chip, when usi...
