Authentication of wearable devices associated with a premises security system

A wearable device configured to communicate with an authentication device associated with a premises security system, the wearable device comprising:

• at least one processor;
• and
• at least one computer-readable medium storing a plurality of instructions that, when executed by the at least one processor, cause the at least one processor to:
• receive a first security token that is usable to validate that the wearable device is authorized to participate in the premises security system;
• in response to the wearable device being worn, validate, using the first security token, the wearable device as being authorized to participate in the premises security system;
• receive a second security token based on the validation that the wearable device is authorized to participate in the premises security system, the second security token being usable for validating that the wearable device is authorized to trigger a premises security system action, the first security token no longer being usable for validation after the transmission of the second security token;
• store the second security token;
• cause transmission of a user request indicating that the wearable device is being worn and that the user requests that the premises security system action be triggered;
• and
• cause transmission of the second security token to trigger the premises security system action.

A method implemented by an authentication device that is associated with a premises security system and configured to communicate with a wearable device, the method comprising:

• causing transmission of a first security token to the wearable device, the first security token being usable to validate that the wearable device is authorized to participate in the premises security system;
• receiving the first security token from the wearable device that is being worn;
• validating that the wearable device is authorized to participate in the premises security system based at least in part on the first security token received from the wearable device;
• in response to validating that the wearable device is authorized to participate in the premises security system based at least in part on the first security token received from the wearable device, causing transmission of a second security token to the wearable device, the second security token being usable for validating that the wearable device is authorized to trigger a premises security system action, the first security token no longer being usable for validation after the transmission of the second security token;
• receiving, from the wearable device, a user request to trigger the premises security system action, the user request further indicating that the wearable device is being worn;
• receiving the second security token associated with the user request;
• and
• triggering the premises security system action based on the user request and the second security token.
