The system includes a repeating encryption and decryption data processing device comprising a first constant array storing unit, a first data registering unit and a first data converting unit. The first constant array storing unit stores a first constant array and send it to N-data converting sub-units of the first data converting unit. The first data registering unit registers data, deliver the registered data to a first data converting sub-unit. The N-data converting sub-units perform a data conversion processing, and transmit the obtained conversion data to a next data converting sub-unit for subsequent processing until the data conversion processing processes are completed, a particular number of the completed processed being equal to a value of a data depth.
