Cuestión central

El intercambio de paquetes en IKEv2 es radicalmente diferente de cuáles estaba en IKEv1. Considerando que en IKEv1 había un intercambio claramente demarcado phase1 que consistió en 6 paquetes seguidos por un intercambio de la fase 2 que consistido en 3 paquetes, el intercambio IKEv2 es variable. Para información más detallada sobre las diferencias y una explicación del intercambio de paquetes, refiera al intercambio de paquetes IKEv2 y al debugging del nivel del protocolo.

El respondedor verifica y procesa el mensaje IKE_INIT:
  1. Elige la habitación crypto de ésas ofrecidas por el iniciador.
  2. Computa su propia clave secreta DH.
  3. También computa un valor del skeyid, del cual todas las claves se pueden derivar para este IKE_SA. Se cifran y se autentican todos pero las encabezados de todos los mensajes que siguen. Las claves usadas para la protección del cifrado y de la integridad se derivan de SKEYID y se conocen como: a. SK_e (cifrado). b. SK_a (autenticación). c. SK_d se deriva y se utiliza para la derivación del material de codificación adicional para CHILD_SAs. Un SK_e y un SK_a separados se computa para cada dirección.

El iniciador comienza el intercambio “IKE_AUTH” y comienza la generación del payload de la autenticación. El paquete IKE_AUTH contiene:
  1. Encabezado ISAKMP (versión/indicadores SPI/).
  2. IDI (la identidad del iniciador).
  3. Payload AUTH.
  4. SAi2 (inicia el SA-similar a la fase 2 transforman el intercambio del conjunto en IKEv1).
  5. TSi y TSr (selectores del tráfico del iniciador y del respondedor): Contienen a las direcciones de origen y de destino del iniciador y el respondedor respectivamente a remitir/recibe el tráfico encriptado. El intervalo de direcciones especifica que todo el tráfico a y desde ese rango será tunneled. Si la oferta es aceptable por el respondedor, devuelve las cargas útiles idénticas TS.
El 1r CHILD_SA se crea para el par del proxy_ID que hace juego el paquete del activador. Configuración pertinente:

El paquete IKE_AUTH enviado de ASA2 contiene:
  1. Encabezado ISAKMP (versión/indicadores SPI/).
  2. IDR (la identidad del respondedor).
  3. Payload AUTH.
  4. SAr2 (inicia el SA-similar a la fase 2 transforman el intercambio del conjunto en IKEv1).
  5. TSi y TSr (selectores del tráfico del iniciador y del respondedor): Contienen a las direcciones de origen y de destino del iniciador y el respondedor respectivamente a remitir/recibe el tráfico encriptado. El intervalo de direcciones especifica que todo el tráfico a y desde ese rango será tunneled. Estos parámetros son idénticos al que fue recibido de ASA1.
