Abstract

The invention discloses a private key encryption method and device. The method comprises the steps that a random number and a private key are acquired, the random number comprises N sections of randomnumbers, the random number is composed of N sections of random numbers, N is an integer larger than 1, and at least one section of random number in the N sections of random numbers is stored in a code operated by a node storing the private key; and a symmetric key is generated according to the N sections of random numbers, and the private key is encrypted according to the generated symmetric key.The random number of the encrypted private key comprises N sections, part of the N sections of random data can be stored in the running code of the node, and part of the random number can also be stored in other positions, so that the technical problem that the private key is easy to steal due to the fact that the private key storage mode is simple in the prior art is solved.

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...
