Abstract

본 발명은 기록장치로 입력되는 입력데이터를 암호화함과 더불어 기록장치로부터 출력되는 출력데이터를 복호화함으로써 정보의 누출이 방지될 수 있도록 된 보안기능을 갖는 디지탈기록장치에 관한 것으로, 디지탈 기록 및 재생장치에 있어서, A/D컨버터(10)로부터 입력되는 입력데이터를 암호화하여 암호화된 입력데이터를 기록장치에 기록함과 더불어 상기 기록장치에 기록된 암호데이터를 복호화하여 출력장치로 출력하는 비화기(17)를 구비하여 구성된 것을 특징으로 한다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital recording apparatus having a security function capable of preventing leakage of information by encrypting input data input to a recording apparatus and decrypting output data output from the recording apparatus. An encryption apparatus (17) for encrypting input data input from the A / D converter (10) to record encrypted input data in a recording device, and decrypting the encrypted data recorded in the recording device and outputting the encrypted data to the output device. Characterized in that provided with.
