Secure communication engine based on the Wandboard PICO-PI-IMX6 applications processor. The module offers a unique secure sensor, that provides two cost-optimized integration options, and ultra-low power operation using seamlessly integrated Microcontroller Assist capabilities.
Secure IP-based wireless sensor via a trusted gateway
As the IP-integration of wireless sensor networks enables end-to-end interactions, solutions to appropriately secure these interactions with hosts on the Internet are necessary. The propose approach that relies on a trusted gateway to mitigate the high cost of the DTLS handshake in the WSN and to provide the flexibility necessary to support a variety of security requirements. The approach leads to considerable energy savings and latency reduction when compared to a standard DTLS use case, while requiring no changes to the end hosts.
In sensor gateway, the security of a sensor network cannot be assessed by simply considering the feasible set of attacks in isolation. To accurately determine the security of a network, one must be able to determine the interdependencies between these attacks and how they can be exploited to execute a multistage attack on the sensor networks. These situations demand the need of risk assessment for a sensor network.
The project, will design risk modeling on both layers with the help of attack graphs and assess the interdependencies between the possible set of attacks on both of these layers and integrate them to assess the overall security of the sensor. Attack graphs in a combination with principles like Bayesian networks will also help in estimating which of the given attack sets are most feasible to execute on the physical sensor layer and how that will affect the virtual layer on the gateway to implementing the security measures using the principles of network hardening strategies for the sensor gateway.
The Gateway includes a wide variety of wired and wireless connections, including serial connections. The I/O on the intelligent device makes it easy to connect your legacy industrial systems and your new mesh networks. The Gateway uses Wi-Fi, WWAN and Ethernet to connect and communicate. Then the processing power of the Gateway supports middleware to aggregate, convert and normalize data from all the disparate protocols – from ModBus to BACnet to ZigBee and more...
