Abstract

A processor communicating with a first memory configured to store first information and first data, and communicating with a second memory configured to store second information and second data, includes a computing unit configured to perform computation using the first data and the second data; an storing unit configured integrally with the computing unit to store first authentication information and second authentication information; a reading unit configured to read out the first information and the second information; an authenticating unit configured to authenticate the first memory by comparing the first information and the first authentication information, and to authenticate the second memory by comparing the second information and the second authentication information; and an controlling unit configured to control an access of the computing unit to the first memory and the second memory based on a result of the authentications.
