Diameter 프로토콜에서는 송수신되는 메시지가 아무런 문제없이 중간 경유 노드에서 변경, 삭제, 추가될 수 있다. Diameter CMS Security Application은 공개키 기반 구조를 이용하여 Diameter 응용에서 종단간 보안 기능을 제공함으로서 이러한 문제점을 해결하였다. Diameter CMS Security Application은 두 종단 노드 사이에 DSA(Diameter Security Association)을 설정하여 이후의 통신의 안전성을 보장하도록 하고 있다. 그러나 시스템 장애 등의 이유로 한 노드가 DSA 정보를 분실하였을 경우, 이 Application을 사용한 두 노드 사이의 안전한 통신에는 문제가 발생하게 된다. MIP(Mobile IP)와 같은 응용에서는 이러한 문제로 사용자 등록이 불가능하여 서비스가 이루어지지 못할 수도 있다. 따라서 본 논문에서는 이러한 경우 DSA를 재설정 할 수 있는 방법을 제시하고 이 해결책을 실제 구현한 결과를 보인다.
