Abstract

The invention relates to the technical field of block chains, in particular to a confidential data management method, electronic equipment, a storage medium and a program product. The method is applied to a client side and comprises the steps that confidential data and N pieces of verification information are obtained, and N is an integer larger than 0; according to a secret sharing algorithm, dividing the confidential data into N data fragments, and determining one piece of corresponding verification information for each data fragment; n trusted execution nodes are determined, and the trusted execution nodes are nodes containing trusted execution environments; and respectively transmitting the N data fragments and the verification information corresponding to the N data fragments to the N trusted execution nodes, so that each trusted execution node stores the data fragments and the corresponding verification information. The method is used for overcoming the defect that a confidential data management mechanism is poor in safety and reliability in the prior art, and high reliability of confidential data management is achieved.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a confidential data management method, electronic equipment, storage media and program products. Background technique [0002] Confidential data includes private data or data that can prove the identity of the user. For example, in a blockchain application scenario, the user's identity and asset certificate is an account, which is essentially a globally unique public-private key pair. Users with a private key have ownership and use rights of assets under the corresponding public key account. Therefore, the user needs to keep the private key properly, because once lost, the user will permanently lose the assets on the blockchain he owns. At this time, the private key is a kind of confidential data. In order to manage private key data safely and conveniently, the most common solution for users is to use blockchain account management software (commonly known as "wallet"). T...
