Abstract

The invention discloses a method and device for encryption management, and relates to the technical field of computers. A specific implementation of the method includes: receiving a configuration request from a target node or a peer node; using an encryption machine to hash the first node number, the second node number and the hash time into a first original key; based on the first original key The key generates a seed key, and returns the first node number, the second node number, the seed key and their generation time to the target node and the opposite node; The node number, the seed key and its generation time are used for the interaction between the target node and the peer node. This embodiment can safely and effectively manage the transmission key, solve the security problem of data transmission, and ensure the confidentiality, integrity and consistency of the data.

Description

technical field [0001] The present invention relates to the field of computer technology, and in particular, to a method and device for encryption management. Background technique [0002] With the advancement of informatization work, the various business systems of enterprises and companies are independent of each other, which leads to a series of security problems such as sensitive data transmission, data security storage, transaction message transmission, etc. These problems may lead to data leakage and file damage. Destruction and other security risks may cause immeasurable economic losses. [0003] Data and information security has attracted more and more attention from the public, which is a challenge and an opportunity for enterprises and companies. It can provide better data security protection, and will surely gain the trust of users, thereby occupying more markets. Strengthening the protection ability of data security, for enterprises and companies, is not only se...
