핵심 문제

IKEv2의 패킷 교환은 IKEv1의 패킷 교환과 근본적으로 다릅니다. IKEv1에서는 6개의 패킷으로 구성된 명확한 경계 1단계 교환이 있었고 그 뒤에 3개의 패킷으로 구성된 2단계 교환이 있었던 반면, IKEv2 교환은 변수입니다.패킷 교환의 차이점과 설명에 대한 자세한 내용은 IKEv2 패킷 교환 및 프로토콜 수준 디버깅을 참조하십시오.

Responder는 IKE_INIT 메시지를 확인하고 처리합니다.
  1. 개시자가 제공하는 암호화 제품군을 선택합니다.
  2. 자체 DH 비밀 키를 계산합니다.
  3. 또한 이 IKE_SA에 대해 모든 키를 파생시킬 수 있는 skeyid 값을 계산합니다.뒤에 오는 모든 메시지의 헤더를 제외한 모든 헤더가 암호화 및 인증됩니다.암호화 및 무결성 보호에 사용되는 키는 SKEYID에서 파생되며 다음과 같습니다.a.SK_e(암호화).b.SK_a(인증).c. SK_d는 CHILD_SA에 대한 추가 키 자료의 파생에 사용되며 파생됩니다.각 방향에 대해 별도의 SK_e 및 SK_a가 계산됩니다.

IKEv2-PROTO-3: (16): Complete SA init exchange
  
개시자는 "IKE_AUTH" 교환을 시작하고 인증 페이로드 생성을 시작합니다.IKE_AUTH 패킷에는 다음이 포함됩니다.
  1. ISAKMP 헤더(SPI/버전/플래그).
  2. IDi(개시자의 ID).
  3. AUTH 페이로드 .
  4. SAi2(IKEv1에서 2단계 변환 세트 교환과 유사한 SA를 시작합니다.)
  5. TSi 및 TSr(Initiator 및 Responder Traffic 선택기):암호화된 트래픽을 전달/수신하기 위해 각각 initiator와 responder의 소스 및 목적지 주소를 포함합니다.주소 범위는 해당 범위에서 들어오고 나가는 모든 트래픽이 터널링되도록 지정합니다.제안서가 응답자에게 수락될 경우 동일한 TS 페이로드를 다시 전송합니다.

ASA2에서 전송된 IKE_AUTH 패킷에는 다음이 포함됩니다.
  1. ISAKMP 헤더(SPI/버전/플래그).
  2. IDr.(응답자의 ID).
  3. AUTH 페이로드.
  4. SAr2(IKEv1에서 2단계 변환 세트 교환과 유사한 SA를 시작합니다.)
  5. TSi 및 TSr(Initiator 및 Responder Traffic 선택기):암호화된 트래픽을 전달/수신하기 위해 각각 Initiator 및 Responder의 소스 및 목적지 주소를 포함합니다.주소 범위는 해당 범위에서 들어오고 나가는 모든 트래픽이 터널링되도록 지정합니다.이러한 매개변수는 ASA1에서 수신한 매개변수와 동일합니다.

ASA2는 CHILD_SA 교환을 시작합니다.CREATE_CHILD_SA 요청입니다.CHILD_SA 패킷에는 일반적으로 다음이 포함됩니다.
  1. SA HDR(version.flags/exchange type)
  2. Nonce Ni(선택 사항):CHILD_SA가 초기 교환의 일부로 생성된 경우 두 번째 KE 페이로드와 nonce는 전송하지 않아야 합니다.
  3. SA 페이로드
  4. KEi(키 선택 사항):CREATE_CHILD_SA 요청은 CHILD_SA에 대한 전달 비밀의 강력한 보장을 위해 추가 DH 교환에 대한 KE 페이로드를 선택적으로 포함할 수 있습니다.?SA 제안에 다른 DH 그룹이 포함된 경우 KEi는 응답자가 수락할 것으로 예상하는 그룹의 요소여야 합니다.?잘못된 것으로 추정하면 CREATE_CHILD_SA 교환은 실패하며 다른 IKE를 사용하여 재시도해야 합니다.
  5. N(Notify payload-optional):Notify Payload는 오류 조건 및 상태 전환과 같은 정보 데이터를 IKE 피어로 전송하는 데 사용됩니다.알림 페이로드는 응답 메시지(일반적으로 요청이 거부된 이유를 지정), 정보 교환(IKE 요청에 없는 오류를 보고하기 위해) 또는 발신자 기능을 나타내거나 요청의 의미를 수정하기 위해 다른 메시지에 나타날 수 있습니다.이 CREATE_CHILD_SA 교환이 IKE_SA 이외의 기존 SA를 재생성하는 경우 REKEY_SA 유형의 선행 N 페이로드가 다시 키가 지정된 SA를 식별해야 합니다.?이 CREATE_CHILD_SA 교환이 기존 SA를 재지정하지 않으면 N 페이로드를 생략해야 합니다.
  6. TSi 및 TSr(선택 사항):SA가 생성된 트래픽 선택기를 표시합니다.이 경우 호스트 192.168.1.12과 192.168.2.99 사이에 있습니다.
