Abstract

The embodiment of the invention provides a data processing method and device, a client stores a first private key component, a server stores a second private key component, and the method comprises the following steps: responding to a transaction data processing request, initiating an identity verification request, and carrying out bidirectional identity verification with the server; and after theverification is passed, calling a first MPC node preset at the client side to take the first private key component as input, and a second MPC node preset at the server to take the second private keycomponent as input, carrying out preset function operation according to a preset rule to obtain a transaction signature, and carrying out transaction data processing. According to the scheme, the transaction private key is firstly split, and then the first private key component and the second private key component which are split are separately stored; in the use process, MPC nodes on the two sides are called to jointly participate in operation through the private key components to generate a transaction signature, and therefore the technical problem that the secret key is not safe to use is solved, and the control power of a user on the complete transaction private key is met.

Description

technical field [0001] The present application relates to the technical field of the Internet, and in particular to a data processing method and device. Background technique [0002] When processing transaction data, it is often necessary to generate a corresponding transaction signature as a transaction certificate, and then complete the corresponding transaction data processing according to the transaction signature. For example, according to the user's transaction signature, call the fund data corresponding to the user's account to pay for the transaction order, etc. [0003] At present, most of the existing transaction data processing methods require the user to save and manage a complete key (such as a transaction private key) through the client used; when processing transaction data, the complete key is obtained and used. key to generate a transaction signature to complete the processing of the corresponding transaction data. [0004] When the above method is impleme...
