建立 Matter 裝置測試憑證

某些開發情境 (例如 OTA 測試) 需要建立非正式環境 Matter 憑證。

Google 生態系統的部分功能 (包括裝置 OTA 軟體更新) 無法使用測試 VID/PID 執行。

本指南說明如何建立及驗證非正式環境 Matter 憑證,以便用於測試。憑證類型如下:

  1. 認證聲明 (CD)
  2. 產品認證中繼憑證 (PAI)
  3. 裝置認證憑證 (DAC)

在授權程序中,Matter 認證裝置必須認證自身,也就是證明其為正版 Matter 認證產品。Matter 裝置用於認證的憑證包含:

  1. 認證金鑰組
  2. 憑證鏈

裝置認證憑證 (DAC) 是憑證鏈結的第一個連結,由產品認證中繼憑證 (PAI) 驗證,而 PAI 則由產品認證授權單位 (PAA) 驗證。

憑證會在產生認證金鑰組時一併簽署,並使用上一層憑證授權單位的私密金鑰簽署,形成信任鏈。因此,DAC 憑證由 PAI 金鑰簽署,PAI 憑證則由 PAA 金鑰簽署。PAA 憑證位於鏈結頂端,屬於自行簽署的憑證。 這個信任鏈會形成聯合 PAA 結構,並由分散式法規遵循總帳 (DCL) 同步。

如要進一步瞭解認證程序和認證聲明 (CD),請參閱其他認證文件和訊息和 Matter 規格。

安裝 Matter SDK

這些操作說明假設您已安裝 Matter SDK。詳情請參閱 GitHub 上的說明文件,或參閱「開始使用 Matter」。

如果尚未安裝 hexdump 公用程式 xxd,請先安裝。這項工具可用於以 C 樣式格式列印憑證:

sudo apt-get install xxd

建構作業「chip-cert」

  1. 請確認您使用的是最新版 SDK。這些程序已在 GitHub SHA 0b17bce8 的 v1.0-branch 分支版本上測試:

    $ cd connectedhomeip
    $ git checkout v1.0-branch
    $ git pull
    
  2. 建構 chip-cert,這項工具可用於對 Matter 裝置的憑證執行多項作業:

    1. 設定建構作業:

      $ cd src/credentials
      $ source ../../scripts/activate.sh
      $ gn gen out
      

      gn 輸出內容範例:

      Done. Made 5774 targets from 289 files in 658ms
      
    2. 執行版本:

      $ ninja -C out
      

      ninja 輸出內容範例:

      ninja: Entering directory `out'
      [2000/2000] stamp obj/default.stamp
      

鑄造憑證

將自訂 VID/PID 匯出為環境變數,降低編輯指令引數時發生筆誤的機率:

$ cd ../..
$ export VID=hexVendorId
$ export PID=hexProductId

生成 CD

  1. 使用 chip-cert 生成 CD。目前,Commissioner 只會驗證 VID 和 PID 是否與裝置在其他位置公開的資料相符:基本資訊叢集、DAC 和 DAC 來源 (如有)。其他欄位則可維持不變:

    $ src/credentials/out/chip-cert gen-cd \
      --key credentials/test/certification-declaration/Chip-Test-CD-Signing-Key.pem \
      --cert credentials/test/certification-declaration/Chip-Test-CD-Signing-Cert.pem \
      --out credentials/test/certification-declaration/Chip-Test-CD-${VID}-${PID}.der \
      --format-version "1" \
      --vendor-id "${VID}" \
      --product-id "${PID}" \
      --device-type-id "0x1234" \
      --certificate-id "ZIG20141ZB330001-24" \
      --security-level "0" \
      --security-info "0" \
      --version-number "9876" \
      --certification-type "0"
    
  2. 驗證 CD。請確認其中包含 VID/PID (十進位格式):

    $ src/credentials/out/chip-cert print-cd credentials/test/certification-declaration/Chip-Test-CD-${VID}-${PID}.der
    

    輸出內容範例:

    SignerKeyId value: hex:62FA823359ACFAA9963E1CFA140ADDF504F37160
    0x01, tag[Anonymous]: 0xffffffff, type: Structure (0x15), container:
    0x04,     tag[Context Specific]: 0x0, type: Unsigned Fixed Point (0x04), value: 1
    0x08,     tag[Context Specific]: 0x1, type: Unsigned Fixed Point (0x04), value: XXXXX // <- VID
    0x0A,     tag[Context Specific]: 0x2, type: Array (0x16), container:
    0x0D,         tag[Anonymous]: 0xffffffff, type: Unsigned Fixed Point (0x04), value: XXXXX // <- PID
    0x12,     tag[Context Specific]: 0x3, type: Unsigned Fixed Point (0x04), value: 4660
    0x15,     tag[Context Specific]: 0x4, type: UTF-8 String (0x0c), length: 19, value: "ZIG20141ZB330001-24"
    0x2B,     tag[Context Specific]: 0x5, type: Unsigned Fixed Point (0x04), value: 0
    0x2E,     tag[Context Specific]: 0x6,type: Unsigned Fixed Point (0x04), value: 0
    0x32,     tag[Context Specific]: 0x7, type: Unsigned Fixed Point (0x04), value: 39030
    0x35,     tag[Context Specific]: 0x8, type: Unsigned Fixed Point (0x04), value: 0
    

產生 PAI 和 DAC

在本範例中,我們將使用 Matter 自己的測試產品認證授權單位 (PAA) 憑證和簽署金鑰 Chip-Test-PAA-NoVID 做為根憑證。我們會將其做為根 CA,產生自己的 PAI 和 DAC。

  1. 使用 PAA 生成 PAI。您可以選擇在 PAI 中加入 PID 資訊,但省略這項資訊可讓測試更具彈性。如需其他 PID 的 DAC,可以只執行 DAC 生成步驟:

    $ src/credentials/out/chip-cert gen-att-cert --type i \
      --subject-cn "Matter Test PAI" \
      --subject-vid "${VID}" \
      --valid-from "2021-06-28 14:23:43" \
      --lifetime "4294967295" \
      --ca-key credentials/test/attestation/Chip-Test-PAA-NoVID-Key.pem \
      --ca-cert credentials/test/attestation/Chip-Test-PAA-NoVID-Cert.pem \
      --out-key credentials/test/attestation/"test-PAI-${VID}-key".pem \
      --out credentials/test/attestation/"test-PAI-${VID}-cert".pem
    
  2. 使用 PAI 產生 DAC:

    $ src/credentials/out/chip-cert gen-att-cert --type d \
      --subject-cn "Matter Test DAC 0" \
      --subject-vid "${VID}" \
      --subject-pid "${PID}" \
      --valid-from "2021-06-28 14:23:43" \
      --lifetime "4294967295" \
      --ca-key credentials/test/attestation/"test-PAI-${VID}-key".pem \
      --ca-cert credentials/test/attestation/"test-PAI-${VID}-cert".pem \
      --out-key credentials/test/attestation/"test-DAC-${VID}-${PID}-key".pem \
      --out credentials/test/attestation/"test-DAC-${VID}-${PID}-cert".pem
    
  3. 驗證 DAC、PAI 和 PAA 鏈結。如果輸出內容未顯示任何錯誤,表示憑證認證鏈結已成功驗證:

    $ src/credentials/out/chip-cert validate-att-cert \
    --dac credentials/test/attestation/"test-DAC-${VID}-${PID}-cert".pem \
    --pai credentials/test/attestation/"test-PAI-${VID}-cert".pem \
    --paa credentials/test/attestation/Chip-Test-PAA-NoVID-Cert.pem
    
  4. 您可以使用 openssl 檢查金鑰:

    $ openssl ec -noout -text -in \
      credentials/test/attestation/test-DAC-${VID}-${PID}-key.pem
    

    輸出內容範例:

    read EC key
    Private-Key: (256 bit)
    priv:
        c9:f2:b3:04:b2:db:0d:6f:cd:c6:be:f3:7b:76:8d:
        8c:01:4e:0b:9e:ce:3e:72:49:3c:0e:35:63:7c:6c:

        46:b9:19:60:28
    ASN1 OID: prime256v1
    NIST CURVE: P-256
    
  5. 您也可以使用 openssl 檢查產生的憑證:

    $ openssl x509 -noout -text -in \
      credentials/test/attestation/test-DAC-${VID}-${PID}-cert.pem
    

    輸出內容範例:

PAA

您可以使用類似程序產生自行簽署的 PAA,但並非必要。

我們在這裡使用的是現有的自行簽署開發 PAA,不含 VID 資訊。

如需更多產生 CD 的範例,請參閱 credentials/test/gen-test-cds.sh。如需更多產生 PAA、PAI 和 DAC 的範例,請參閱 credentials/test/gen-test-attestation-certs.sh。

更換憑證

更換 PAA 和 PAI

  1. 執行下列輔助指令碼,使用 CHIP 憑證工具 (chip-cert) 產生憑證的 C 樣式陣列。

下載 Embeddable Certificates Helper 指令碼

      rm "${cert_file_der}"
  fi
  "${chip_cert_tool}" convert-cert "${cert_file_pem}" "${cert_file_der}" --x509-der

  printf "};\n\n"
  printf "ByteSpan k${type}PrivateKey = ByteSpan(${type}_PrivateKey_Array);\n\n"
}

# generates PAI
printcert

cert_file_pem="${folder}/test-DAC-${VID}-${PID}-cert.pem"
key_file_pem="${folder}/test-DAC-${VID}-${PID}-key.pem"

# generates DAC
printcert

printf "#endif // CHIP_DEVICE_CONFIG_DEVICE_PRODUCT_ID\n"
printf "} // namespace DevelopmentCerts\n"
printf "} // namespace chip\n"
  1. 將 PAI 和 DAC 輸出內容複製到 DeviceAttestationCredentialsProvider::GetProductAttestationIntermediateCert 的實作項目。

    在正式版裝置上,PAI 和 DAC 位於原廠資料中,而 CD 則內嵌在韌體本身。

    1. 如果您尚未使用原廠資料,建議您將 PAI 放在 src/credentials/examples/ExampleDACs.cpp 中。在這種情況下,請將產生的程式碼附加到 ExampleDACs.cpp 檔案:

      ByteSpan kDacCert       = ByteSpan(kDevelopmentDAC_Cert_FFF1_801F);
      ByteSpan kDacPrivateKey = ByteSpan(kDevelopmentDAC_PrivateKey_FFF1_801F);
      ByteSpan kDacPublicKey  = ByteSpan(kDevelopmentDAC_PublicKey_FFF1_801F);
      #endif
      } // namespace DevelopmentCerts
      } // namespace chip
      
      /* ------------------------------------------ */
      /* current end-of-file                        */
      /* ------------------------------------------ */
      
      /* ------------------------------------------ */
      /* output of creds-codelab.sh script          */
      /* ------------------------------------------ */
      
      namespace chip {
      namespace DevelopmentCerts {
      
      #if CHIP_DEVICE_CONFIG_DEVICE_PRODUCT_ID == hexProductId
      
      ...
      
      ByteSpan kDacPrivateKey = ByteSpan(Dac_PrivateKey_Array);
      
      #endif // CHIP_DEVICE_CONFIG_DEVICE_PRODUCT_ID
      } // namespace DevelopmentCerts
      } // namespace chip
      
    2. 如果您使用 Factory Data 或自訂憑證供應器,請務必在適當位置插入憑證。建議您向 SoC 供應商確認平台的具體資訊。

更換 CD

  1. 使用 xxd 擷取 CD 檔案內容的文字表示法:

      $ xxd -i credentials/test/certification-declaration/Chip-Test-CD-${VID}-${PID}.der
    

    輸出內容範例:

      unsigned char credentials_test_certification_declaration_Chip_Test_CD_hexVendorId_hexProductId_der[] = {
        0x30, 0x81, 0xe9, 0x06, 0x09, 0x2a, 0x86, 0x48, 0x86, 0xf7, 0x0d, 0x01,

        0x05, 0x00, 0x24, 0x06, 0x00, 0x25, 0x07, 0x76, 0x98, 0x24, 0x08, 0x00,
        0x18, 0x31, 0x7d, 0x30, 0x7b, 0x02, 0x01, 0x03, 0x80, 0x14, 0x62, 0xfa,
        0x82, 0x33, 0x59, 0xac, 0xfa, 0xa9, 0x96, 0x3e, 0x1c, 0xfa, 0x14, 0x0a,

        0x48, 0x01, 0x65, 0x03, 0x04, 0x02, 0x01, 0x30, 0x0a, 0x06, 0x08, 0x2a,
        0x86, 0x48, 0xce, 0x3d, 0x04, 0x03, 0x02, 0x04, 0x47, 0x30, 0x45, 0x02,
        0x20, 0x53, 0x25, 0x03, 0x2c, 0x96, 0x50, 0xb6, 0x64, 0xf4, 0x18, 0xbf,
        0x99, 0x47, 0xf8, 0x9d, 0xe6, 0xeb, 0x43, 0x94, 0xf1, 0xce, 0xb2, 0x61,
        0x00, 0xe0, 0xf9, 0x89, 0xa8, 0x71, 0x82, 0x02, 0x0a, 0x02, 0x21, 0x00,
        0xea, 0x0a, 0x40, 0xab, 0x87, 0xad, 0x7e, 0x25, 0xe1, 0xa1, 0x6c, 0xb1,

        0x85, 0x46, 0x50, 0xb6, 0xd0, 0x55, 0x40, 0xe2
      };
      unsigned int credentials_test_certification_declaration_Chip_Test_CD_hexVendorId_hexProductId_der_len = 236;
      ```
    
  2. 將上一步擷取的文字複製到用於定義 CD 的檔案,並加入建構作業。與 PAI 和 DAC 的情況一樣,具體做法取決於您開發的平台。

如果您使用憑證範例,可能需要替換 src/credentials/examples/DeviceAttestationCredsExample.cpp 中 ExampleDACProvider::GetCertificationDeclaration 的 kCdForAllExamples 內容:

建構目標

使用新建立的憑證建構及刷新目標。本節內容因平台而異。詳情請參閱 SoC 說明文件或支援的裝置。

委任裝置

現在,您可以按照「配對 Matter 裝置」一節所述的步驟,在 Google Home platform 上委任 Matter 裝置。

使用 chip-tool 偵錯

chip-tool 是實用的工具,可用來檢查裝置是否傳送正確的憑證。建構方式如下:

$ cd examples/chip-tool
$ gn gen out/debug
Done. Made 114 targets from 112 files in 157ms
$ ninja -C out/debug
ninja: Entering directory `out/debug'
$ cd ../..

如要啟用其他記錄,請務必在執行 chip-tool 時傳遞 --trace_decode 1 旗標。此外,建議您使用 --paa-trust-store-path 旗標傳遞 PAA 檔案的路徑。

因此,如要使用 BLE 委任 Thread 裝置,可以執行:

```
$ examples/chip-tool/out/debug/chip-tool pairing ble-thread 1 \
  hex:Thread_credentials \
  pairing_code \
  discriminator \
  --paa-trust-store-path <path to PAA folder> \
  --trace_decode 1
```

如果是測試裝置,<PAIRING CODE> 為 20202021,<DISCRIMINATOR> 則為 3840。

如要從 Google Nest Hub (2nd gen) 取得 Thread 憑證,請執行以下指令:

$ adb connect border_router_ip_address
$ adb -e shell ot-ctl dataset active -x
$ adb disconnect

如要註冊 Wi-Fi 裝置,可以使用 ble-wifi 選項:

$ examples/chip-tool/out/debug/chip-tool pairing ble-wifi 1 "SSID" SSID_password pairing_code discriminator
