Abstract:
A differencing generator generates difference data between a first data set and a second data set. An encryption unit encrypts data. An electronic signature generator generates the electronic signature of data. A transmission data generator generates transmission data. The encryption unit encrypts the difference data generated by the differencing generator so as to generate encrypted difference data. The transmission data generator generates transmission data containing both the encrypted difference data generated by the encryption unit and the electronic signature of the second data set as generated by the electronic signature generator.
