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.
Claims20
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 using the shared 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 further communications from the headset to the device, when the response is valid;
- otherwise, disabling further communications from the headset to the device.
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;
- creating a response to the challenge by the headset using the shared key;
- validating the response by the seat device;
- and
- enabling further communications from the headset to the seat device, when the response is valid;
- otherwise, disabling further communications from the headset to the seat device.
A system comprising:
- a device 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;
- and
- a 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 so, enables the further communications from the headset;
- otherwise, if the response is invalid, disables further communications from the headset.
