Key management method, key use method, key management device, key use device and key use equipment

Abstract

The embodiment of the invention provides a secret key management method, a secret key use method, a secret key use device and equipment. The method comprises the steps: receiving a registration request sent by a user side, and enabling the registration request to comprise an identity identification of a user; generating a user key corresponding to the identity identifier; splitting the user key into a plurality of key slices; and combining the key slices according to a preset rule and then sending the key slices to each key node for storage, wherein each key node comprises a trusted mechanism node and a client node. According to the embodiment of the invention, the user key is split into the key slices, one part is stored in the credible institution node, and the other part is stored in the client node, so that the user key is not easy to lose; meanwhile, the user secret keys are dispersed in different secret key nodes, the possibility that all the nodes are attacked by the network is extremely low, the user secret keys are not prone to leakage, and the safety of the user secret keys is guaranteed.

Description

technical field [0001] Embodiments of the present disclosure relate to the technical field of data encryption in financial technology (Fintech), and in particular, to a key management method, key usage method, device, and equipment. Background technique [0002] With the development of computer technology, more and more technologies are applied in the financial field. The traditional financial industry is gradually transforming into Fintech, and data encryption technology is no exception. However, due to the security and real-time requirements of the financial industry, It also puts forward higher requirements for data encryption technology. [0003] At present, the key management of traditional financial-level data mainly includes two types: the first one is to encrypt and decrypt user data using the user key encryption institution key pair, and the user key client is stored locally, that is, the user key storage It is on the client side and is the unique user key; the use...

AI Technical Summary

Problems solved by technology

[0004] However, the inventor found that the existing key management has at least the following technical problems: when the user key is stored locally, it is easy to lose, and it cannot be retrieved after being lost, resulting in easy loss of the user key; Trusted escrow organization, because the trusted escrow organization network may be attacked, causing user key leakage

That is to say, the traditional key management has been lost, and the security of user keys cannot be guaranteed
