Method, apparatus, and computer program product for improving security for wireless communication
First Claim
1. A method, comprising:
- receiving, by an apparatus, one or more wireless discovery messages;
determining, by the apparatus, whether a wireless device is in close proximity and within touching range to the apparatus based on information obtained from the one or more received wireless discovery messages;
exchanging, by the apparatus, messages with the wireless device in response to having determined that the wireless device is in close proximity to the apparatus;
transmitting or receiving, by the apparatus, a request to establish a secure communications session with the wireless device;
measuring, by the apparatus, signal strength of the exchanged messages while distance changes to the wireless device while within close proximity;
determining, by the apparatus, whether changes in the measured signal strength of the exchanged messages satisfy a predetermined behavior expected for signal strength when in close proximity to the wireless device as distance varies; and
establishing, by the apparatus, the secure communications session with the wireless device, in response to determining that the changes in the measured signal strength of the exchanged messages satisfy the predetermined behavior expected for signal strength as distance varies.
