Abstract
A set of certificates are received at a gateway device from a management server, where each one of the certificates was generated by the management server upon determination that the gateway device is associated with a respective wireless sensing device (WSD). The gateway device receives from a first WSD an advertisement message indicating it is available for connecting to a gateway device. In response to confirming based on a first certificate of the set of certificates associated with the first WSD, that it is authorized to connect to the WSD, the gateway device transmits to the first WSD the first certificate and an identifier of the gateway device for enabling authentication of the gateway device at the WSD. The gateway device receives data from the first WSD, upon confirmation at the WSD that it is authorized to connect with the gateway device.
