Security Pane; Ssp Versus Non-Ssp Pairings; Debug Mode - Ellisys Bluetooth Explorer 400 User Manual

15. Security Pane

The Security pane displays encryption-related information and allows for various user inputs.
The Security pane will update as traffic is recorded, and can be saved with the capture,
alleviating the need to re-enter link keys on successive captures. The Security pane also
accepts user-entry of link keys, a private key, PIN codes, and user-defined device names.
Security pane features include:
Link key, authenticated ciphering offset (ACO), and PIN code displays

Automatic deciphering of PIN codes and calculation of link keys from non-SSP pairings

User entry of link keys to enable the software to decrypt related traffic

Entry of friendly device names for easier recognition throughout the application

Selectable timestamp indicators for pairings that are linked to the Overview

Alerts for incomplete pairings, PIN code conflicts, missing link key, incorrect link key

A utility to calculate public keys from a private key

To access the Security pane:
1. Select View | Security from the menu.
The Security pane appears:

15.1 SSP versus Non-SSP Pairings

For PIN-code pairings, the analyzer will decipher the PIN code, calculate the link key, and
decrypt all related packets, all without user intervention.
For SSP pairings, the user can enter the link key during a recording, or on a static or saved
capture. The software will then decrypt the traffic. If an HCI interface is being captured, the
software will automatically extract the link key from the captured HCI traffic and use this for
decrypting the traffic automatically.

15.2 Debug Mode

When Debug Mode is used, the analyzer will use the pre-defined Diffie Hellman private key and
public keys that are used with this mode to automatically decrypt the traffic.
