思科已使用電腦和人工技術翻譯本文件，讓全世界的使用者能夠以自己的語言理解支援內容。請注意，即使是最佳機器翻譯，也不如專業譯者翻譯的內容準確。Cisco Systems, Inc. 對這些翻譯的準確度概不負責，並建議一律查看原始英文文件（提供連結）。

    簡介

    本文檔介紹有關思科自適應安全裝置(ASA)上的網際網路金鑰交換版本2 (IKEv2)調試的資訊。

    必要條件

    需求

    本文件沒有特定需求。

    採用元件

    本文件所述內容不限於特定軟體和硬體版本。

    本文中的資訊是根據特定實驗室環境內的裝置所建立。文中使用到的所有裝置皆從已清除（預設）的組態來啟動。如果您的網路運作中，請確保您瞭解任何指令可能造成的影響。

    核心問題

    IKEv2中使用的資料包交換過程與IKEv1中使用的資料包交換過程截然不同。使用IKEv1時，有一個由六個資料包組成的明確分界階段1交換，然後是一個由三個資料包組成的階段2交換。IKEv2交換是可變的。

    提示：有關這些差異的更多詳細資訊以及資料包交換過程的解釋，請參閱IKEv2資料包交換和協定級調試。

    使用的調試

    以下兩個調試用於IKEv2：

    debug crypto ikev2 protocol 127
    debug crypto ikev2 platform 127

    調試

    本部分介紹ASA1（啟動器）和ASA2（響應器）隧道協商以及子安全關聯(SA)調試和消息說明。

    通道交涉

    ASA1接收與對等體ASA 10.0.0.2的加密訪問控制清單(ACL)匹配的資料包，並啟動SA建立：

    IKEv2-PLAT-3: attempting to find tunnel 
         group for IP: 10.0.0.2
      IKEv2-PLAT-3: mapped to tunnel group 10.0.0.2 
         using peer IP
      IKEv2-PLAT-3: my_auth_method = 2
      IKEv2-PLAT-3: supported_peers_auth_method = 2
      IKEv2-PLAT-3: P1 ID = 0
      IKEv2-PLAT-3: Translating IKE_ID_AUTO to = 255
      IKEv2-PLAT-3: (16) tp_name set to:
      IKEv2-PLAT-3: (16) tg_name set to: 10.0.0.2
      IKEv2-PLAT-3: (16) tunn grp type set to: L2L
      IKEv2-PLAT-5: New ikev2 sa request admitted
      IKEv2-PLAT-5: Incrementing outgoing negotiating 
       sa count by one

    傳送的初始消息對用於IKE_SA_INIT交換。這些消息協商加密演算法、交換隨機數，並執行Diffie-Hellman (DH)交換。

    以下是ASA1的相關配置：

    crypto ikev2 policy 1
      encryption aes-256
      integrity sha
      group 2
      prf sha
      lifetime seconds 86400
    crypto ikev2 enable outside
      
    Tunnel Group matching the identity name is present:
      
    tunnel-group 10.0.0.2 type ipsec-l2l
    tunnel-group 10.0.0.2 ipsec-attributes
      ikev2 remote-authentication pre-shared-key *****
      ikev2 local-authentication pre-shared-key *****

    以下是此交換的調試輸出：

         Event: EV_GET_CONFIG_MODE
    IKEv2-PROTO-5: (16): SM Trace-> SA: I_SPI=DFA3B583A4369958

    然後，ASA1構建IKE_INIT_SA資料包，其中包含：

    • ISAKMP標頭（SPI/版本/旗標）

    • SAi1（IKE啟動器支援的加密演算法）

    • KEi（發起方的DH公鑰值）

    • N （發起方隨機數）

    然後，ASA1會傳送IKE_INIT_SA資料包：

    IKEv2-PLAT-4: SENT PKT [IKE_SA_INIT]
         [10.0.0.1]:500->[10.0.0.2]:500

    ASA2接收IKEV_INIT_SA資料包：

    IKEv2-PLAT-4: RECV PKT [IKE_SA_INIT]
          [10.0.0.1]:500->[10.0.0.2]:500
          InitSPI=0xdfa3b583a4369958 RespSPI=0x0000000000000000
        MID=00000000

    ASA2會為該對等體啟動SA建立：

    IKEv2-PROTO-3: Rx [L 10.0.0.2:500/R 
         10.0.0.1:500/VRF i0:f0] m_id: 0x0

    ASA2驗證並處理IKE_INIT消息：

    1. 它從ASA1提供的加密套件中選擇加密套件。

    2. 它計算自己的DH金鑰。

    3. 它還計算SKEYID值，從中可以派生出此IKE_SA的所有金鑰。所有郵件（除接下來的所有郵件報頭外）均經過加密和身份驗證。用於加密和完整性保護的金鑰是從SKEYID派生的，稱為：

      • SK_e用於加密。

      • SK_a用於身份驗證。

      • SK_d是衍生的，用於衍生CHILD_SA的進一步金鑰材料。會針對每個方向計算單獨的SK_e和SK_a。

    以下是ASA2的相關配置：

    crypto ikev2 policy 1
      encryption aes-256
      integrity sha
      group 2
      prf sha

    ASA之間的IKE_INIT_SA交換現已完成：

    IKEv2-PROTO-3: (16): Complete SA init exchange

    ASA1啟動IKE_AUTH交換並開始生成身份驗證負載。IKE_AUTH資料包包含：

    • ISAKMP標頭（SPI/版本/旗標）

    • IDi （初始器辨識）

    • 身份驗證負載

    • SAi2（啟動SA -類似於IKEv1中的階段2轉換集交換）

    • TSi和TSr（發起方和響應方流量選擇器）

    注意：TSi和TSr分別包含發起方和響應方的源地址和目標地址，用於轉發/接收加密流量。地址範圍指定所有進出該範圍的流量都透過隧道傳輸。如果響應方可以接受該建議，則它會返回相同的TS有效負載。

    此外，還會為與觸發資料包匹配的proxy_ID對建立第一個CHILD_SA。

    ASA1將IKE_AUTH資料包傳送到ASA2：

    ASA2從ASA1接收此資料包：

    IKEv2-PLAT-4: RECV PKT [IKE_AUTH] 
         [10.0.0.1]:500->[10.0.0.2]:500

    ASA2會停止授權計時器並驗證從ASA1接收的身份驗證資料。然後，它會生成自己的身份驗證資料，與ASA1完全相同。

    以下是ASA2的相關配置：

    ASA2傳送IKE_AUTH資料包，其中包含：

    • ISAKMP標頭（SPI/版本/旗標）

    • IDr.（響應方身份）

    • 身份驗證負載

    • SAr2（啟動SA -類似於IKEv1中的階段2轉換集交換）

    • TSi和TSr（發起方和響應方流量選擇器）

    注意：TSi和TSr分別包含發起方和響應方的源地址和目標地址，用於轉發/接收加密流量。地址範圍指定所有進出該範圍的流量都透過隧道傳輸。這些引數與從ASA1收到的引數相同。

    子SA調試

    注意：此交換由單個請求和響應對組成，在IKEv1中稱為第2階段交換。初始交換完成後，IKE_SA的任何一端都可以啟動它。

    ASA2啟動CHILD_SA交換。這是CREATE_CHILD_SA請求。CHILD_SA資料包通常包含：

    • SA HDR -包含version.flags和交換型別。

    • Nonce Ni （可選） -如果建立CHILD_SA作為初始交換的一部分，則不得傳送第二個金鑰交換(KE)負載和nonce。

    • SA負載

    • KEi (Key-optional) - CREATE_CHILD_SA請求可以選擇包含用於附加DH交換的KE負載，以便為CHILD_SA啟用更強的前向保密保證。如果SA提供包括不同的DH組，則KEi必須是發起方期望響應方接受的組的元素。如果它猜測錯誤，CREATE_CHILD_SA交換將失敗，它必須使用其他KEi重試。

    • N （通知有效載荷，可選）-通知有效載荷用於將資訊資料（例如錯誤條件和狀態轉換）傳輸到IKE對等體。通知負載可以出現在響應消息（通常指定請求被拒絕的原因）、資訊交換（以便報告不在IKE請求中的錯誤）或任何其他消息中，以便指示傳送方功能或修改請求的含義。如果此CREATE_CHILD_SA交換對IKE_SA以外的當前SA重新生成金鑰，則REKEY_SA型別的前N個負載必須標識重新生成金鑰的SA。如果此CREATE_CHILD_SA交換未對當前SA重新生成金鑰，則必須省略N個負載。

    • TSi和TSr（可選）：這顯示為其建立SA的流量選擇器。在本例中，它位於主機192.168.1.12和192.168.2.99之間。

    ASA1現在為CHILD_SA交換構建應答。這是CREATE_CHILD_SA響應。CHILD_SA資料包通常包含：

    • SA HDR -包含version.flags和交換型別。

    • Nonce Ni （可選）-如果建立CHILD_SA作為初始交換的一部分，則不得傳送第二個KE有效負載和nonce。

    • SA負載

    • KEi （Key，可選） - CREATE_CHILD_SA請求可以選擇包含用於附加DH交換的KE負載，以便為CHILD_SA啟用更強的前向保密保證。如果SA提供包括不同的DH組，則KEi必須是發起方期望響應方接受的組的元素。如果它猜測錯誤，CREATE_CHILD_SA交換將失敗，必須使用其他KEi重試。

    • N （通知有效載荷，可選）-通知有效載荷用於將資訊資料（如錯誤條件和狀態轉換）傳輸到IKE對等體。通知負載可以出現在響應消息（通常指定請求被拒絕的原因）、資訊交換（以報告不在IKE請求中的錯誤）或任何其他消息中，以指示傳送方功能或修改請求的含義。如果此CREATE_CHILD_SA交換對IKE_SA以外的當前SA重新生成金鑰，則REKEY_SA型別的前N個負載必須標識重新生成金鑰的SA。如果此CREATE_CHILD_SA交換未對當前SA重新生成金鑰，則必須省略N個負載。

    • TSi和TSr（可選）-這顯示為其建立SA的流量選擇器。在本例中，它位於主機192.168.1.12和192.168.2.99之間。
