Method of controlling electronic device using wearable device and method of operating electronic device
First Claim
1. A method of controlling an electronic device using a wearable device, comprising:
- pairing, by the wearable device, the electronic device with the wearable device;
receiving, by the wearable device, a cryptographic key from the electronic device;
storing the cryptographic key in a secure storage device included in the wearable device;
estimating, by the wearable device and subsequent to the pairing, a distance between the wearable device and the electronic device as an estimated distance by transmitting a detection signal to the electronic device, receiving a response signal transmitted from the electronic device in response to the detection signal, and calculating the estimated distance based on an intensity of the response signal; and
automatically transmitting an unlock signal including the cryptographic key, which is stored in the secure storage device, from the wearable device to the electronic device when the estimated distance is closer than a threshold distance,wherein the electronic device is automatically unlocked based on the unlock signal including the cryptographic key, andwherein the unlock signal is independent from user input to the electronic device.

Abstract
In a method of controlling an electronic device using a wearable device, the electronic device is paired with the wearable device. A cryptographic key, which corresponds to the electronic device, is stored in a secure storage device included in the wearable device. A distance between the wearable device and the electronic device is estimated by the wearable device. An unlock signal including the cryptographic key, which is stored in the secure storage device, is transmitted from the wearable device to the electronic device when the estimated distance is smaller than a threshold distance. The electronic device is unlocked based on the unlock signal.
