Methods and systems for offload of data from a wireless sensing device to a gateway device. A certificate that is generated by the management server in response to a determination that the gateway device is associated with a wireless sensing device is received during an initial connection with the management server. In response to confirming, based on the certificate, that the gateway device is authorized to connect to the wireless sensing device, the certificate is transmitted to the wireless sensing device; and data is received from the wireless sensing device in response to confirming that the wireless sensing device is authorized to connect with the gateway device based on the certificate.

Authentication of a gateway device in a sensor network

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.

Methods and systems for secure data offload in a sensor network. The method comprises offloading data indicative of sensor measurements from a wireless sensing device to a gateway device through a first secure communication channel; and storing the data at the gateway device if there is not currently a second secure communication channel established between the gateway device and the management server. The method continues with offloading the data to the management server when the second secure communication channel is established; and reconciling the data at the management server to generate reconciled sensor measurements in which duplicates have been removed.

Secure offline data offload in a sensor network

A method in a wireless sensing device for authenticating a gateway device of a sensor network is described. The method includes receiving a certificate where the certificate was generated by the management server upon a determination that the gateway device and the wireless sensing device are associated and is a digital document including data and a digital signature, where the digital signature was generated by the management server based on the data and a private key of the management server, and where the data includes a first identifier and a second identifier; confirming that the wireless sensing device is authorized to upload data to the gateway device; in response to the confirming that the wireless sensing device is authorized to upload data to the gateway device, uploading to the gateway device data indicative of a plurality of sensor measurements taken over time to be transmitted to the management server.
