Key storage and acquisition method and device

Abstract

The invention discloses a key storage method and device and a key obtaining method and device. The key storage method comprises the steps of obtaining a first key, wherein the first key is the key needing to be protected; generating a second key and encrypting the first key through adoption of the second key, thereby obtaining a first ciphertext; generating a third key and encrypting the second key through adoption of the third key, thereby obtaining a second ciphertext; and independently storing the first ciphertext, the second ciphertext and the third key, thereby obtaining the first key according to the first ciphertext, the second ciphertext and the third key. According to the method, the storage security of the key can be improved and the information security can be ensured.

Description

technical field [0001] The present invention relates to the technical field of information security, in particular to a key storage and acquisition method and device. Background technique [0002] With the development of computer technology and the popularity of the Internet, people pay more and more attention to information security. To ensure information security, encryption protocols such as Transport Layer Security (TLS) appear. The TLS protocol is based on an asymmetric encryption algorithm to distribute the public key through a certificate authorized by a digital certificate authority (Certificate Authority, CA), and the private key corresponding to the public key is properly kept on the server side. [0003] At present, when the server saves the private key, it is stored in the local file of the server in the form of plain text. However, the plaintext format can easily cause the private key to be leaked and affect information security. Contents of the invention ...
