          Abstract

          The emergence of radio technologies, such as Zigbee, Z-Wave, and Bluetooth Mesh, has transformed simple physical devices into smart objects that can understand and react to their environment. Devices, such as light bulbs, door locks, and window blinds, can now be connected to, and remotely controlled from, the Internet. Given the resource-constrained nature of many of these devices, they have typically relied on the use of universal global shared secrets for the initial bootstrapping and commissioning phase. Such a scheme has obvious security weaknesses and it also creates undesirable walled-gardens where devices of one ecosystem do not inter-operate with the other. In this paper, we investigate whether the standard Extensible Authentication Protocol (EAP) framework can be used for secure bootstrapping of resource-constrained devices. EAP naturally provides the benefits of per-device individual credentials, straightforward revocation, and isolation of devices. In particular, we look at the Nimble out-of-band authentication for EAP (EAP-NOOB) as a candidate EAP authentication method. EAP-NOOB greatly simplifies deployment of such devices as it does not require them to be pre-provisioned with credentials of any sort. Based on our implementation experience on off-the-shelf hardware, we demonstrate that lightweight EAP-NOOB is indeed a way forward to securely bootstrap such devices.

            Demonstration of 575-Mb/s downlink and 225-Mb/s uplink bi-directional SCM-WDM visible light communication using RGB LED and phosphor-based LED.

            We propose and experimentally demonstrate a novel full-duplex bi-directional subcarrier multiplexing (SCM)-wavelength division multiplexing (WDM) visible light communication (VLC) system based on commercially available red-green-blue (RGB) light emitting diode (LED) and phosphor-based LED (P-LED) with 575-Mb/s downstream and 225-Mb/s upstream transmission, employing various modulation orders of quadrature amplitude modulation (QAM) orthogonal frequency division multiplexing (OFDM). For the downlink, red and green colors/wavelengths are assigned to carry useful information, while blue chip is just kept lighting to maintain the white color illumination, and for the uplink, the low-cost P-LED is implemented. In this demonstration, pre-equalization and post-equalization are also adopted to compensate the severe frequency response of LEDs. Using this scheme, 4-user downlink and 1-user uplink transmission can be achieved. Furthermore, it can support more users by adjusting the bandwidth of each sub-channel. Bit error rates (BERs) of all links are below pre-forward-error-correction (pre-FEC) threshold of 3.8x 10(-3) after 66-cm free-space delivery. The results show that this scheme has great potential in the practical VLC system.
