Abstract

The invention provides a key management server, a client, a key distribution method and a key acquisition method. The client sends a key request to the key management server, the key management server receives the key request, the key management server acquires a key and an identifier of the key from a local key source, the key management server sends the identifier of the key to the client, and the client receives the identifier of the key because the client and the key management server are both provided with local key sources, and the local key sources at the two ends store the same corresponding relationship between the key and the identifier; therefore, the client can obtain the key plaintext corresponding to the identifier from the local key source. According to the method and the device, the key is transmitted between the key management server and the client through the identifier of the key and the local key source, so the network transmission of the key plaintext is avoided, the leakage of the key plaintext is avoided, and the security of the key transmission process is improved.

Description

technical field [0001] The present application relates to the technical field of data encryption, and in particular to a key management server, a client, a key distribution method and a key acquisition method. Background technique [0002] With the rapid development of Internet technology, various businesses are gradually realizing informatization and networking. While Internet technology brings convenience to the development of various businesses, it also brings security risks. These security risks may lead to leakage and tampering of users' sensitive data. It can be seen that in today's network era, data security is an important issue that cannot be easily ignored. [0003] Currently, in the Internet environment, users encrypt sensitive data and use a Key Management Service (Key Management Service, KMS) system to manage keys. In the key management process of the existing key management service system, the key management service system generates the key plaintext, encrypt...
