An Improved Protocol for Verifiable Polynomial Cloud Outsourcing Computation

Abstract

The cloud computing industry is booming, which involves a large amount of data transmission and calculation, and polynomial calculation is the most basic calculation. Since polynomial calculations have extremely high requirements on the computing power of computing equipment, in most cases, the computing equipment in the user’s hands cannot meet the computing requirements. The user needs to calculate but has no way to do it by himself. In this case, the computing task must be handed over to the cloud server. Aiming at the untrustworthy problem of the cloud server environment, an improved verifiable polynomial cloud outsourcing computing protocol scheme based on the previous outsourcing computing protocol is proposed to ensure the security of the computing process, the privacy of the computing content, and the verifiability of the computing results. This solution hides all the calculation parameters behind the deformed encrypted parameters, so the cloud server cannot obtain the user’s true parameters during the calculation process, and the calculation results can be verified by the user on the client with minimal computing power.
