建立 Matter 裝置測試憑證

雖然並非必要條件,但某些測試情境需要建立非實際工作環境 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 Test VID/PID 執行。

本指南說明如何建立及驗證非實際工作環境的 Matter 憑證,以便用於測試。憑證的類型如下:

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

在調試過程中,Matter 認證裝置必須自行「認證」,也就是證明該裝置是正版 Matter 認證。Matter 裝置用於認證的憑證包含:

  1. 認證金鑰組
  2. 憑證鏈結

裝置認證憑證 (DAC) 是憑證鏈結的第一個連結,並由產品認證中介憑證 (PAI) 驗證,後者則經過產品認證管理局 (PAA) 驗證。

憑證會在產生認證金鑰組時簽署,並使用上述一層級的憑證授權單位私密金鑰簽署,形成「信任鏈」。因此 DAC 憑證是由 PAI 金鑰簽署,而 PAI 憑證則是由 PAA 金鑰簽署。PAA 憑證位於企業鏈的領導地位,它本身是自行簽署的憑證。這個信任鏈形成一種聯合 PAA 結構,由分散式法規遵循帳本 (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與訊息和 Matter 規格。

安裝 Matter SDK

這些操作說明假設您已順利安裝 Matter SDK。詳情請參閱 GitHub 的說明文件,或參閱「開始使用 Matter」一文。

如果您尚未安裝 160 進位轉儲公用程式 xxd,請進行安裝。此工具很適合用來以 C 樣式顯示憑證:

sudo apt-get install xxd

建構作業「chip-cert

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

    $ cd connectedhomeip
    $ git checkout v1.0-branch
    $ git pull
    
  2. 建構 chip-cert (用於多次對 Matter 裝置憑證進行作業的工具):

    1. 設定版本:

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

      gn 輸出範例:

      Done. Made 5774 targets from 289 files in 658ms
      
    2. 執行建構:

      $ ninja -C out
      

      ninja 輸出範例:

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

建立憑證

將自訂 VID/PID 匯出為環境變數,以減少編輯指令引數時發生結構錯誤的機會:

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

產生 CD

  1. 使用 chip-cert 產生 CD。目前委員會只會驗證 VID 和 PID 是否與裝置其他地方公開的資料相符,也就是基本資訊叢集、DAC 和 DAC 來源 (如果有的話)。您可以保留其他欄位不變:

    $ 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. 檢查 CD。請確認 ID 中包含您的 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

在此範例中,我們會使用 Matter 本身的測試產品認證授權管理局 (PAA) 憑證和簽署金鑰 Chip-Test-PAA-NoVID 做為根憑證。我們會使用這個檔案做為根憑證授權單位,自行產生 PAI 和 DAC。

  1. 使用 PAA 產生 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彈性。如果需要將其他 PID 採用 DAC,可以僅執行 DAC 產生步驟:

    $ 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

程序也可用來產生自行簽署的 PAA,但並非必要。

而是使用不含 VID 資訊的現有自行簽署開發 PAA。

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

替換憑證

更換 PAA 和 PAI

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

下載可嵌入憑證輔助指令碼

#!/bin/bash

#
# generate-embeddable-certs.sh script
# —----------------------------------
#
# This script generates self-minted DAC and PAI.
# The output may easily be included in your C++ source code.

printcert() {
  # convert cert to DER
  if [ -f "${cert_file_der}" ]; then
      rm "${cert_file_der}"
  fi
  "${chip_cert_tool}" convert-cert "${cert_file_pem}" "${cert_file_der}" --x509-der

  printf "// ------------------------------------------------------------ \n"
  printf "// ${type} CERTIFICATE ${cert_file_der} \n\n"

  printf "constexpr uint8_t ${type}_Cert_Array[] = {\n"
  less -f "${cert_file_der}" | od -t x1 -An | sed 's/\/,/g' | sed 's/^/   /g'

  printf "};\n\n"
  printf "ByteSpan k${type}PublicKey = ByteSpan(${type}_PublicKey_Array);\n\n"

  printf "// ${type} PRIVATE KEY FROM ${key_file_pem} \n\n"

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

# generates PAI
printcert

type="Dac"
cert_file_der="${folder}/test-DAC-${VID}-${PID}-cert.der"
cert_file_pem="${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 輸出內容的內容複製到 DeviceAttestationCredentialsProvider::GetProductAttestationIntermediateCert 實作中。

    在正式版裝置上,PAI 和 DAC 位於工廠資料中,CD 則嵌入韌體本身。

    1. 如果您尚未使用工廠資料,可以考慮將 PAI 放入 src/credentials/examples/ExampleDACs.cpp。在此情況下,請將產生的程式碼附加至 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. 如果您使用的是原廠資料或自訂憑證提供者,請務必將憑證插入適當位置。建議您向 SoC 供應商洽詢平台的具體細節。

更換 CD

  1. 使用 xxd 擷取 CD 檔案內容的文字:

      $ 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,
        0xdd, 0xf5, 0x04, 0xf3, 0x71, 0x60, 0x30, 0x0b, 0x06, 0x09, 0x60, 0x86,
        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,
        0x12, 0xfa, 0x86, 0xfe, 0xea, 0x8a, 0xaf, 0x4b, 0xc1, 0xf3, 0x6f, 0x09,
        0x85, 0x46, 0x50, 0xb6, 0xd0, 0x55, 0x40, 0xe2
      };
      unsigned int credentials_test_certification_declaration_Chip_Test_CD_hexVendorId_hexProductId_der_len = 236;
      ```
    
  2. 將在上一步擷取的文字複製到用來定義 CD 的檔案至建構作業中。如同 PAI 和 DAC 的情況,執行方式會因開發平台的平台而異。

如果您使用憑證範例,可能會想要替換 src/credentials/examples/DeviceAttestationCredsExample.cppExampleDACProvider::GetCertificationDeclaration 中的 kCdForAllExamples 內容:

建構目標

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

調試裝置

您現在可以按照「配對 Matter 裝置」一文中的步驟在 Google Home platform 上調用 Matter 裝置。

使用「chip-tool」偵錯問題

chip-tool 是一項檢查裝置是否傳送正確憑證的實用工具。如何建立應用程式:

$ 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,每當執行 chip-tool 時,請務必傳遞 --trace_decode 1 標記。此外,建議您使用 --paa-trust-store-path 旗標傳送 PAA 檔案的路徑。

因此,如要使用 BLE 調用 Thread 裝置,您可以執行:

```
$ 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>20202021<DISCRIMINATOR> 則為 3840

如要從 Google Nest Hub (2nd gen) 取得 Thread 憑證,您可以執行:

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

如要調控 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
