Abstract:
1. A method of defending against a battery exhaustion attack on a wireless communication device, the method comprising: determining, by a processor of a first wireless communications device, whether a battery exhaustion attack against the first wireless communication device has occurred based on a connection state between the first wireless communication device and at least one second wireless communication device; if it is determined that the battery exhaustion attack against the first wireless communication device has occurred, defending the first wireless communication device from the battery exhaustion attack using a communication module of the first wireless communication device; storing, in the communication module, identification information of the at least one second wireless communication device, if it is determined that the battery exhaustion attack against the first wireless communication device has occurred; denying, by the communication module independently from the processor, a connection request from the at least one second wireless communication device based on the stored identification information; and outputting defense history information about the battery exhaustion attack, if a dormant mode of the first wireless communication device is released, wherein the determining whether the battery exhaustion attack against the first wireless communication device as occurred determines that the battery exhaustion attack against the first wireless communication device has occurred if the connection state is that the at least one second wireless communication device that succeeded in a connection request to he first wireless communication device is not pairing with the first wireless communication device for a predetermined period of time.
