Generation protection method and system of encrypted storage key, terminal and readable storage medium

Abstract

The invention provides a generation protection method and system of an encrypted storage key, a terminal and a readable storage medium. The generation protection method comprises the following steps:encrypting a preset protection key and a working key by adopting a preset encryption algorithm, and storing a ciphertext; the user setting a user password through the upper management server and binding the user password to the password device; synthesizing the temporary master key and a preset user password into a preset user password master key; a security module generating a first random number, and performing XOR operation on the first random number and a preset protection key to form a first protection key; comparing the input user password master key with a preset user password master key stored in a security module; if the comparison is passed, passing identity authentication. According to the method and the system, the user identity is discriminated, one-time encryption of the protection key is realized, and the protection strength of the storage protection key is greatly improved. The security module supports safe storage of random number generation, a symmetric cryptographicalgorithm, an asymmetric encryption algorithm and a secret key.

Description

technical field [0001] The invention relates to the technical field of data encryption, in particular to a method for generating and protecting an encrypted storage key, a system, a terminal and a readable storage medium. Background technique [0002] In information systems, whether user data is stored in local storage or cloud storage, there is a risk of data theft and abuse when the protection strength is relatively low. Data is the core asset, and the hard disk, as the final carrier of data storage, is the last line of defense for data protection. Storage security faces increasingly stringent security requirements. [0003] At present, when user data is stored, most of them use passwords, fingerprints, finger veins, etc. for access control, while most of the data is encrypted and protected by using pseudo-random numbers as protection keys when prefabricated or initialized by hard disk manufacturers. Insufficient, data security has great security risks, and it is easy to...

[0003] At present, when user data is stored, most of them use passwords, fingerprints, finger veins, etc. for access control, while most of the data is encrypted and protected by using pseudo-random numbers as protection keys when prefabricated or initialized by hard disk manufacturers. Insufficient, data security has great security risks, and it is easy to be cracked, resulting in the loss of effective protection of data
