Abstract

The embodiment of the invention discloses a method and device for protecting data. A specific embodiment of the method comprises the following steps: collecting a binary file and confidential data of a service; encrypting the confidential data by using the secret key to generate encrypted confidential data; dividing the secret key into a first secret key fragment and a second secret key fragment; embedding the identifier of the key and the first key fragment into a binary file to generate an embedded binary file, and sending the identifier of the key and the second key fragment to a database of a service provider for storage; and sending the embedded binary file and the encrypted confidential data to a server of a user of the service for deployment. According to the confidential data protection method based on safe multi-party calculation, the confidential data of the service can be effectively protected.

Description

technical field [0001] The embodiments of the present application relate to the field of computer technologies, and in particular to methods and devices for protecting data. Background technique [0002] At present, when the service provider provides external services, in some cases, due to the network environment restrictions of the service user, the service provider may be required to deploy the service offline to the server of the service user. Therefore, the service provider will package and deploy the binary file of the service and some core confidential data to the server of the service user. In this way, the user of the service can use the service through the binary file and core confidential data provided by the service provider without connecting to the external network. The provider of the service hopes that the core secret data can only be used by the binary files deployed by itself. However, directly deploying the core confidential data to the server of the use...
