Abstract

암호화 통신을 단시간에 실시하는 것을 목적으로 한다.And aims at performing encryption communication in a short time.

암호화 화상통신장치는, 화상데이타를 확대 또는 축소화하는 화상사이즈 변경수단과, 화상데이터를 암호화하는 암호화 수단과, 그 암호화 데이타를 부호화 하는 부호화 수단과, 그 부호화 데이터를 송신하는 송신수단등을 구비하고 있고, 제어 수단에 의하여 화상데이터를 소정의 사이즈로 설정한 후, 부호화 하여 송신한다. 더우기, 제어수단에 의하여 화상데이터의 암호화처리는 통신전의 수순 실행등과 병행하여 실시됨과 아울러, 암호송신 에러가 발생한 경우에는 암호화 데이터의 재차 송신이 실시된다.The encrypted video communication apparatus includes image size changing means for enlarging or reducing image data, encryption means for encrypting the image data, encoding means for encoding the encryption data, transmission means for transmitting the encoded data, and the like And the image data is set to a predetermined size by the control means, and is then encoded and transmitted. Further, the encryption processing of the image data by the control means is performed in parallel with the procedure execution before the communication, and when the encryption transmission error occurs, the encrypted data is transmitted again.
