Abstract

The invention discloses a method for protecting a key. The method is applied to a device for storing the key, and comprises the following steps: obtaining a request instruction of using the key sent by an application object, wherein the request instruction comprises identity verification information; judging whether the identity verification information is matched with the application object; andif so, opening use permission of the target key corresponding to the request instruction, and otherwise, limiting the use permission of the target key. Therefore, by adoption of the method, the problem of confused use of the key can be effectively prevented, and the security of the key is improved. In addition, the invention also provides an apparatus for protecting the key and a computer readablestorage medium, which also have the above advantageous effects.

Description

technical field [0001] The present invention relates to the technical field of computer information security, in particular to a method, device and computer-readable storage medium for protecting keys. Background technique [0002] With the rapid development of the Internet, more and more attention has been paid to information security. A key is a parameter that is entered in an algorithm that converts plaintext to ciphertext or ciphertext to plaintext. In order to realize the secure transmission of information, usually, it is necessary to perform encryption and decryption through corresponding keys, so as to protect the security of information. [0003] In the prior art, multiple keys are stored in the same hardware device, and this hardware device needs to be used repeatedly in different application systems. Obviously, the keys corresponding to different application systems are usually different. In other words, each application system has its own corresponding key. Enc...
