Embodiment Construction

[0054] In order to make the purpose, features and advantages of the present invention more obvious and understandable, the technical solutions in the present invention will be clearly and completely described below in conjunction with the drawings in the specific embodiments of the present invention.

[0055] Such as figure 1 As shown, the present invention provides an identity-based closed key management method, which is characterized in that it includes the following steps:

[0056] Step 1. Submit an identity authentication request to the identity authentication server when the user logs in, and return the user token after the identity authentication is passed;

[0057] Step 2. When the user needs encryption and decryption services, submit the token and user data to the encryption and decryption service module;

[0058] Step 3. The encryption and decryption service module submits the user token to the key management server, and requests the user data key;

[0059] Step 4. ...

Abstract

The invention provides an identity-based closed key management method and system. The method comprises the following steps: 1, an identity authentication request is submitted to an identity authentication server when a user logs in, and a user token is returned upon successful identity authentication; 2, when the user requires encryption / decryption service, the token and user data are submitted toan encryption / decryption service module; 3, the encryption / decryption service module submits the user token to a key management server, and requests a user data key; 4, the key management server requests the identity authentication server to verify the validity of the token, and the key management server searches for user data key ciphertext through a user ID upon successful verification; 5, thekey management server obtains user data key plaintext through decryption and returns the user data key plaintext to the encryption / decryption service module; and 6, the encryption / decryption service module carries out encryption / decryption operation on the user data through the user data key, and returns an encryption / decryption result. The system comprises the identity authentication server, thekey management server, a hardware security module, and the encryption / decryption service module.

Description

technical field [0001] The invention belongs to the field of information security, and in particular relates to an identity-based closed key management method and system. Background technique [0002] In recent years, with the rapid development and wide application of cloud computing, the data security of cloud computing services has become a huge obstacle to the application and promotion of cloud computing, which has attracted widespread attention. The cloud computing architecture is characterized by multi-tenant, distributed and shared resources, making it difficult to solve data security issues on cloud computing services. [0003] The traditional key management system and data encryption method are realized by hardware encryption machine. The user is directly responsible for the management of the key management system and the user IC key card. The key management is separated from the user management. The cost is high, the scalability is poor, and the deployment is not fl...
