Abstract

The invention discloses a key encryption method, a key decryption method, a data encryption method and a data decryption method. The key encryption method comprises the following steps: acquiring a first key and equipment identification information of the electronic equipment, generating a second key according to the equipment identification information, encrypting the first key by using the second key, and generating an encrypted key. In the embodiment of the invention, the first key is encrypted by using the equipment identification information, so that the security of the first key can be effectively ensured, and the security of data encryption is improved; and meanwhile, the first key is encrypted by using the equipment identification information, and the encryption security of the first key is greatly improved based on the uniqueness of the equipment identification information.

Description

technical field [0001] The present application relates to the field of encryption technology, in particular to a key encryption method, a decryption method, a data encryption method, and a decryption method. Background technique [0002] With the rapid development of the Internet and mobile networks, various network security issues have emerged, and network security has increasingly become one of the focuses of people's attention. Since the development of network security, there are relatively mature frameworks and theories, and there are many scenarios and methods involved, such as cryptography, infrastructure security, access control, authentication management, transmission security, and sensitive data protection. If important data involving identity information, confidential information, and personal privacy are leaked, it will pose a great threat to users' assets and safety. For the protection of these important data, it is common to use a key to encrypt these data. Ho...
