- 클라이언트 단말이 웹정합 프록시서버를 매개하여 유료의 정보를 제공받기 위해 정보제공서버에 인증절차를 실행하는 데이터통신네트워크에서의 인증처리방법에 있어서,상기 클라이언트 단말의 유료정보요청에 응답하여 상기 웹정합 프록시서버로부터 상기 정보제공서버에 송신될 메시지를 메시지 다이제스트 암호처리하여 생성된 전자서명을 상기 정보제공서버에 전달하는 제 1과정과;상기 전자서명을 수신한 상기 정보제공서버에서 상기 암호화된 메시지 다이제스트를 복호처리하여 정당한 전자서명인지를 판단한후 정당한 전자서명의 결과판단시에만 해당하는 유료정보 페이지를 상기 웹정합프록시서버를 통해 상기 클라이언트 단말측에 전달되도록 하는 제 2과정으로 이루어진 것을 특징으로 하는 웹정합 프록시서버를 포함하는 데이터통신망에서의 인증처리방법.
- 제 1항에 있어서, 상기 제 1과정에서는 상기 정보제공서버에 송신될 메시지를 해쉬함수에 의해 메시지 다이제스트 암호처리하고 그 메시지 다이제스트에 자신의 개인키를 이용하여 공개키를 암호화하여 상기 정보제공서버에 전송하는 것을 특징으로 하는 웹정합 프록시서버를 포함하는 데이터통신망에서의 인증처리방법.
- 제 1항에 있어서, 상기 제 2과정은 상기 정보제공서버는 상기 웹정합 프록시서버로부터의 전자서명을 그 공개키를 이용하여 복호화하며, 상기 웹정합 프록시서버에 의해 생성된 메시지 다이제스트를 추출하고 상기 정보제공서버는 상기 수신된 메시지에 상기 정보제공서버와 동일한 해쉬함수를 적용하여 새로운 메시지 다이제스트를 생성하며 상기 추출된 메시지 다이제스트 와 상기 생성된 메시지 다이제스트를 상호 비교하여 전자서명의 정당성을 판단하도록 된 것을 특징으로 하는 웹정합 프록시서버를 포함하는 데이터통신망에서의 인증처리방법.
