Abstract
PURPOSE:To prevent the interception of a decoded program and a transfer data by allowing a master equipment to select one of various kinds of decoding programs and transferring it to an opposite slave equipment prior to data transmission. CONSTITUTION:A processor A is provided with data encipherment programs PA1-PAN operated on the processor. A and cipher decoding programs PB 1-PBN operated on a processor B. Then the processor A determines a cipher to be implemented, selects one of encipherment programs PA1, PA2-PAN operated on the processor A, selects a decoding program among the programs PB1, PB2...PBN operated on the processor B, transfers it by a transmission means TR to execute the encipherment data transfer thereafter.
