Abstract

통신 네크워크에서 이동 사용자들 간의 통신은 여러가지 비밀유지에 관한 문제를 가지는 데, 사용자 식별 및 사용자 추적은 특히 중요한 두 문제이다. 본 발명은 이동 사용자의 이동을 추적할 수 없게 하면서 이 사용자를 안전하게 식별하는 방법 및 장치를 제공한다. 즉 본 발명은 비밀리에 안전한 사용자 식별을 위한 방식을 제공한다. 요약하면, 비밀 단방향 함수하에서 사용자의 식별자 및/또는 사용자의 패스워드 및 동기화 표시, 바람직하게는 정해진 시간간격을 암호화하고, 소위 “동적 사용자 식별자”인 이 암호 메시지를 사용자가 등록된 사용자의 “홈 당국”으로 전송하는 것이다. 홈 당국은 매 시간간격(또는 또다른 선택된 동기화)에 사전계산되고 리스팅되는 대응 테이블, 동적 사용자 식별자 및 대응하는 사용자의 진정한 신월을 포함하고, 따라서, 수신된 암호 메시지가 등록된 사용자의 것인지를 신속하게 결정할 수 있다. 다른 한편으로, 침입자는 암호 메시지로부터 사용자의 신원을 알아낼 수 없으며 사용자의 이동을 추적할 수 없다.
