Problems solved by technology

Multi-party secure computing is performed on private data through multiple computing devices that do not trust each other, which not only protects private data but also performs data processing on private data. However, the communication complexity of multi-party secure computing in the prior art is very high, resulting in far lower computing efficiency. Due to the needs of users, and the current multi-party secure computing products in the market are based on software implementation, it is impossible to provide users with an integrated multi-party secure computing platform solution

Abstract

The invention provides a multi-party secure computing all-in-one machine. The all-in-one machine comprises a plurality of computing devices, wherein each computing device is configured in an untrustedcomputing system architecture, a multi-party security computing protocol is preset in each computing device, and when a multi-party security computing instruction is received, the multi-party security computing protocol and at least another computing device execute multi-party security computing based on the multi-party security computing protocol and the obtained scattered ciphertext. Accordingto the all-in-one machine, an integrated multi-party security computing platform is provided for users, and a problem of high computing communication complexity of multi-party security computing in the prior art is solved.

Description

technical field [0001] The present application relates to the technical field of data security processing, in particular to a multi-party secure computing all-in-one computer. Background technique [0002] As big data is shared between enterprises, between enterprises and individuals, and between individuals, some private data, such as bank credit ratings, personal identity information, financial transaction information, etc., will be leaked along with the data business. As user behavior and habits are collected digitally, users / companies pay more and more attention to privacy data. Therefore, data sharing business and private data confidentiality have become an increasingly prominent contradiction. [0003] In the prior art, when a computing task requires the joint participation of multiple computing devices, in order to protect the information security of each computing device, each computing device can complete the computing task through multi-party secure computing. Mu...
