WiFi Security
With ComProbe 802.11, the WiFi decryption is not done in the datasource. It is done in the decoders, so you must go to Set Initial Decoder Parameters to provide the security information to the decoder.
From the Control window, select Set Initial Decoder Parameters... from the Options menu.
In the Set Initial Decoder Parameters dialog, select the Security tab. In the tab pane, select the encryption method being using with your device under test (DUT) by clicking on the radio button in the Encrypted Data box.
There are three types of types of encrypted data on the security tab, each one selectable via a radio button.
| Option | Description |
|---|---|
| WPA2 | WPA2 (Wi-Fi Protected Access), and WEP (Wired Equivalent Privacy) data that is transmitted over a 802.11 communications link. There are two values you have to enter for the WPA2 and WEP to be decrypted properly. |
| Bluetooth AMP | The Bluetooth alternative MAC/PHY (AMP) enables Bluetooth to support data rates up to 24 Mbps by using additional wireless radio technologies. |
| Pre-shared Key | The pre-shared key is a 32-byte hex number. |
Within the Set Initial Decoder Parameters... dialog Security tab, the fields available will depend on the Encrypted Data option selected.
Note: When capturing both Bluetooth and 802.11 data using the 802.11AMP capture method, the ComProbe software uses the link from the BR/EDR connection. To automatically decode 802.11 AMP frames in this case, select the Bluetooth AMP Encrypted Data, but leave the Link Key field blank.
| Encrypted Data Option | Field | Description |
|---|---|---|
| WPA2 | WPA2: SSID | The station ID of the 802.11 communications link. |
| WEP: SSID | The station ID of the 802.11 communications link. | |
| WEP: Passkey | The shared passkey phrase used in communications. | |
| Bluetooth AMP | BDR/EDR Link Key | Enter a hexadecimal value for the BR/EDR Link Key. |
| WEP: SSID | The station ID of the 802.11 communications link. | |
| WEP: Passkey | The shared passkey phrase used in communications. | |
| Pre-Shared Key | Raw Hex Key | Enter a 32-byte hex number |
| WEP: SSID | The station ID of the 802.11 communications link. | |
| WEP: Passkey | The shared passkey phrase used in communications. |
Enter the required security data in to the active fields for the selected Encrypted Data option. Click the OK button to set the decoder security parameters.
Wi-Fi security settings are also presented in detail in the Decoder Parameters section (See "Wi-Fi Security Decoder Parameters").
