Abstract

[과 제]
서버기기와 클라이언트기기의 사이에 인테네트 및 타의 통신채널을 사용하여 비밀 데이타를 보내기 위한 시스템을 기술한다.
[해결수단]
클라이언트 기는 주 CPU와 주메모리 및 부가 CPU와 부가 메모리를 포함한다.
클라이언트 기기 속의 부가 CPU 및 메모리는 인터내트접속 또는 다른 통신채널 접속을 통하여, 서비기기의 CPU 및 메모리에 연결되어 있다.
클라이언트 및 서버의 CPU와 메모리는 협동적으로 동시처리적으로 연결되어 있어, 제 3자에게 해독되지 않도록 암호화코드 및 해독코드를 극적으로 수정하여 단일프로세스를 실행한다.
