摘要
Provided is a zero-knowledge proof system that allows a discrete-logarithm zero-knowledge proof. The zero-knowledge proof device includes a temporary memory unit that stores pseudorandom numbers and previously determined hash values, a first processing unit that calculates multiple pseudorandom numbers and performs multiple iterations of processing to calculate hash values based on the calculated pseudorandom numbers and the information stored in the temporary memory unit, a second processing unit that determines some of the multiple pseudorandom numbers based on the hash values, and a third processing unit that re-calculates some of the pseudorandom numbers and sends the hash values obtained to a zero-knowledge verification device. The zero-knowledge verification device includes a temporary memory region, a data receiving module that sequentially receives new input data, and a processing module that overwrites hash values including variables and input data, as variables into the temporary memory region each time the input data are received.
