Abstract

According to one embodiment, a storage stores secret data, first identification data, and a first random key. A generation module generates first authentication data from the secret data, first identification data, and second identification data of a removable medium. A first verification module determines whether the first authentication data and second authentication in the removable medium are identical. A second verification module determines whether the first random key and a second random key in the removable medium are identical, if the first and second authentication data are identical. An activation module activates the data processing apparatus if the first and second random keys are identical.
