Abstract
A method for verifying information in a cloud computing system includes generating, by one or more computation devices, an evaluation key and a verification key in a memory available to at least one of the one or more computation devices based on a security parameter and a function to be evaluated; computing, by the one or more computation devices, an output of the function to be evaluated in a memory available to at least one of the one or more computation devices using an input; computing, by the one or more computation devices, a proof for an outcome using the evaluation key in a memory available to at least one of the computation devices; and verifying, by the one or more computation devices, if the proof is valid based on the verification key in a memory available to at least one of the one or more computation devices.
