Abstract

The invention discloses a private key encryption method and device. Wherein, the method includes: by obtaining a random number and a private key, wherein the random number includes: N segments of random numbers, and the random number is composed of N segments of random numbers, wherein N is an integer greater than 1, and at least A random number is stored in the code run by the node that saves the private key; a symmetric key is generated based on N random numbers, and the private key is encrypted according to the generated symmetric key. That is, the random number of the encrypted private key includes N segments, and part of the N segment random data can be stored in the running code of the node, and part of the random number can also be stored in other locations, thereby solving the problem of storing the private key in the prior art. The method is simple, leading to the technical problem that the private key is easy to be stolen.

Description

technical field [0001] The present invention relates to the field of encryption, in particular to a private key encryption method and device. Background technique [0002] At present, the private keys of most blockchain nodes are stored in the configuration file in clear text. Once the machine is attacked, the private key may be leaked, which will lead to more serious losses, including the theft of digital assets or private data. . Some nodes use ciphertext to store the private key, but the key used for encryption lacks good protection measures and is easy to be stolen, resulting in the leakage of the private key. [0003] For the above problems, no effective solution has been proposed yet. Contents of the invention [0004] Embodiments of the present invention provide a private key encryption method and device to at least solve the technical problem in the prior art that the private key is easily stolen due to the simple way of storing the private key. [0005] Accordi...
