Abstract:
A method and system for establishing two-way trust between a short-range communication device and a hub device. The method includes: obtaining, from a hub device, a digitally signed request for determining whether the hub device is a trusted communication device for a short-range communication device and a cryptographic key generated by the short-range communication device; generating a response to the request; encrypting the response to the request by using the cryptographic key provided by the short-range communication device, so that the encrypted response can be decrypted only by the short-range communication device; and providing the encrypted response to the hub device. The short-range communication device may decrypt the response and determine whether the hub device is the trusted communication device based on information indicated in the response.
