Abstract
본 발명은 무선전화기를 이용하여 전화통화를 수행하는 경우 무선 전화기의 고정장치와 휴대장치간의 송수신 음성신호를 암호화함으로써 전화통화의 내용이 도청되는 것을 방지할 수 있도록 된 보안기능을 갖는 무선전화기에 관한 것으로, 제1컨버터(13)로부터 입력되는 수신음성 디지털신호를 암호화함과 더불어 제2컨버터(15)로부터 입력되는 암호화된 송신음성 디지털신호를 복호화하는 제1비화기(14)를 구비하여 구성된 고정장치(10)와, 제3컨버터(22)로부터 입력되는 암호화된 수신음성 디지털신호를 복호화함과 더불어 제4컨버터(24)로부터 입력되는 송신음성 디지털신호를 암호화하는 제1비화기(23)를 구비하여 구성된 휴대장치(20)로 구성된 것을 특징으로 한다.The present invention relates to a wireless telephone having a security function that can prevent the eavesdropping of the telephone call by encrypting voice signals transmitted and received between the fixed device and the portable device of the wireless telephone when the telephone call is performed using the wireless telephone. And a first activator 14 for encrypting the received voice digital signal input from the first converter 13 and for decrypting the encrypted transmit voice digital signal input from the second converter 15. And a first activator (23) for decrypting the encrypted received voice digital signal input from the third converter (22) and for encrypting the transmitted voice digital signal input from the fourth converter (24). It is characterized by consisting of a portable device 20 provided.
