Abstract

PURPOSE: To make difficult a cipher to be deciphered by a hacker and to improve the safety of communication by changing a ciphering rule by a keyboard or voice input each time the communication is executed.
CONSTITUTION: The keyboard or voice input is coded by a converter 2 and a frame pattern is prepared by a frame synchronizing pattern preparing circuit 3 corresponding to the input. In the converter 2, a value executing the ASCII conversion of the input is defined as the frame pattern in the case of the keyboard input and a value executing the ASCII conversion of a voice recognized result is defined as the frame pattern in the case of a voice. Since the ciphering rule can arbitrarily be changed for each transmission, it is made difficult to monitor a line, to decipher the cipher by a computer and to execute wire tapping, and there is an effect to improve the safety of the communication.
