Ensuring IoT Infrastructure Integrity via Smarter Nodes

Click image to enlarge

Figure 1: The Texas Instruments MSP430 MCU

IoT infrastructure can potentially be compromised in a number of ways. Firstly, there is the possibility that IoT nodes could be damaged during shipment or transport, prior to their installation. Then they might be exposed to harsh conditions, due to the application environment in which they are located - with extreme heat, high humidity or vibrational forces al
