Abstract

According to the encryption method, the decryption method, the electronic equipment and the storage medium provided by the embodiment of the invention, the user password and the first random number ofthe solid state disk are operated through the key generation function to generate the main key for encrypting the data protection key, so that the data protection key can be stored in the solid statedisk in a ciphertext form; meanwhile, due to the uncertainty of the first random number, the cracking difficulty of the master key is improved, the stealing difficulty of the data protection key is further improved, the risk that data in the solid state disk is stolen is reduced, and the safety and reliability of the solid state disk are improved.

Description

technical field [0001] The present application relates to the technical field of data security, in particular, to an encryption method, a decryption method, electronic equipment and a storage medium. Background technique [0002] With the rapid development of solid-state drives as storage media, the encrypted storage of user data inside solid-state drives has become a research direction for secure storage technologies at home and abroad. [0003] At present, the encryption method for solid-state hard drives is usually only to encrypt user data, and the key for encrypting user data is stored in the solid-state hard drive in plain text without any protective measures, which is very easy to be stolen, reducing the Security and reliability of SSD data storage. Contents of the invention [0004] In view of this, the purpose of the present application is to provide an encryption method, a decryption method, an electronic device and a storage medium, so as to improve the securit...
