First Claim
Patent Images
1. A machine implemented method, the method comprising:
- storing a shared key on a device of a transportation vehicle and on a headset;
generating a challenge for the handset by the device, using the shared key after the headset is connected to the device;
presenting the challenge to the headset by the device;
creating a response to the challenge by the headset using the shared key;
presenting the response to the device;
determining using the shared key by the device whether the response is valid or invalid;
enabling further communications from the headset to the device, and the device to the headset, when the response is valid;
when the response is invalid, disabling further communication from the headset to the device, while the headset continues to receive audio from the device to operate only as a passive audio listening device; and
disabling by the device, a data line for the headset for receiving communication from the headset, after the headset is disconnected from the device.

Abstract
Methods and systems for a transportation vehicle are provided. For example, one method includes storing a key on a device of a transportation vehicle and a headset; generating a challenge by the device using the key when the headset is connected to the device; presenting the challenge to the headset by the device; creating a response to the challenge by the headset; presenting the response to the device; validating the response by the device; and enabling a data line for the headset by the device when the response is valid.

9. A machine implemented method for authenticating a headset on an aircraft, the method comprising:
-
generating a challenge by a seat device of the aircraft using a shared key after the headset is connected to a universal serial bus (USB) port and powered by a power line prior to being authenticated; creating a response to the challenge by the headset using the shared key; determining using the shared key by the seat device, whether the response is valid or invalid; enabling further communications from the headset to the seat device and the seat device to the headset, when the response is valid; and when the response is invalid, disabling further communications from the headset to the seat device while the headset continues to receive audio from the from the seat device to operate only as a passive audio listening device; and disabling by the seat device, a data line for the headset for receiving communication from the headset, after the headset is disconnected from the seat device. - View Dependent Claims (10, 11, 12)

13. A system comprising:
-
a device of a transportation vehicle including a memory containing machine readable medium comprising machine executable code and a key;
a processor module coupled to the memory, the processor module configured to execute the machine executable code to generate a challenge by the device using the key, and a port including a data line that is disabled by default; anda headset including processing logic, memory storing another the key, a challenge generator executable by the processing logic using the key, and a cable extending therefrom, the cable having a terminal insertable into the port; wherein when the terminal is plugged into the port of the device, the machine executable code of the device generates the challenge and presents the challenge to the headset, the processing logic of the headset creates a response to the challenge using the key in the memory of the headset and presents the response to the device, and the machine executable code of the device determines if the response is valid, and if the response is valid, enables further communication from the headset to the device, and the device to the headset;
otherwise, if the response is invalid, disables further communication from the headset to the device, while the headset continues to receive audio from the device to operate as a passive audio listening device;wherein when the terminal is removed from the port, the machine executable code of the device disables the data line to prevent unauthenticated communication from the headset. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
