INFORMATION PROCESSOR, INFORMATION PROCESSING METHOD AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an information processor capable of reducing execution time of a secure calculation protocol.SOLUTION: The information processor includes: a first calculation protocol generation section that generates a first calculation protocol including no secrecy ensuring protocol which is executed for ensuring the secrecy of the input value based on a secure calculation protocol for calculating an output value by plural arithmetic processing devices based on plural input values; and a second calculation protocol generation section that generates a second calculation protocol by disposing the secrecy ensuring protocol at a position where the secrecy in the first calculation protocol is secured.
