Abstract

The invention provides a secret information processing method, device and system. The secret information processing method is applied to a data storage system and comprises steps of: receiving a data storage request and secret information required to be stored which are sent by a client; generating a master key and a data key of the client based on a client identifier in the data storage request, encrypting the data key by using the master key, returning the encrypted data key to the client, encrypting the secret information by using the data key, and storing the obtained encrypted secret information while deleting the data key. Thus, even if the encrypted secret information is invalidly acquired, the encrypted secret information cannot be decrypted via the data key because of the absence of the data key. Since the data key obtained from the client is encrypted by the master key of the client, the secret information cannot be decrypted even if the data key encrypted by the client is intercepted. As a result, dual protection is formed, encrypted storage of the secret information is achieved and data security is improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a secret information processing method, device and system. Background technique [0002] In recent years, more and more people are accustomed to using the Internet for shopping, entertainment and other activities. [0003] In the process of using the Internet, users often use important information, such as the signature of the website API interface, the user's password, the certificate of the application, etc. We call these data secret information. These secret information are usually stored in the data storage system of the target accessed by the user, such as a cloud server. [0004] With the continuous development of the Internet, network security issues are becoming more and more prominent. If the cloud server is maliciously attacked by illegal elements, the secret information will be destroyed, changed or leaked, which may cause users to be unable to...
