Sodera LE Datasource Security Pane

The Security pane is where the Frontline software identifies devices with captured traffic () that contain pairing, authentication, or encrypted data. The pane will show fields for entering keys, and will show if the keys are valid or invalid.

Successful decryption of captured data requires datasource receipt of all the critical packets and either :

• be given the link key by the user, or
• observe the pairing process and determine the link key.

See for a description of the critical packets. The Security pane will identify the type of key required for decryption.

The Security pane shows events in the current capture. When the (missing or bad snippet) button is clicked, all devices with active traffic that require decryption are shown. Security events appear in starting time order with the most recent event at the bottom.

• Status: displays icons showing the pairing and encryption/decryption status.

  Icon	Description
  	Pairing/Authentication attempt observed but was unsuccessful
  	Devices successfully Paired/Authenticated.
  	Encrypted: traffic is encrypted but there is insufficient information to decrypt. See for a description of the critical packets.
  	Decrypted

• Time: Beginning and end time of the security context. No end time is indicated by an "…". Beginning time is shown in the first row of the grouping. End time is shown in the second row.
• Master: The BD_ADDR of the master device in the link. If the friendly name is available it will show on the second line.

• Slave: The BD_ADDR of the slave device in the link. If the friendly name is available it will show on the second line.

  Note: If the Master and Slave switch roles another entry will appear in the Security pane

  

  Role Switch Example

• PIN/TK:
  • Bluetooth low energy
    • PIN: 6 digit numeric passkey (000000 - 999999)
    • Out-of-Band Temporary Key (OOB TK): 32 digit hexadecimal number
• Link Key
  • Bluetooth low energy, 32 digit hexadecimal number
  • The Link Key cell displays "Enter link key" in gray when the link key is unknown. When a link is invalid the cell has a light red background and indented gray text under the link key says "Invalid". When a link key is valid the cell has a light green background and indented gray text under the link key says "Valid" (if the link key was transformed from the entered link key the text is "Valid (Reordered)".
  • If Sodera LE is Analyzing and a link key has not been entered, "Stop analyzing to enter link key" appears in the device Link Key cell. Click the Analyzing button to stop the analysis, and type or paste in the link key.
  • Users can enter the device security information by typing directly on the device fields PIN/TK and Link Key. An invalid entry will display a red background and a warning Invalid.
• IV: Initialization Vector is displayed for both Bluetooth low energy encryption . The slave will use the IV in starting the encrypted communications.
