IoT reference design promises end-to-end security
Inherent to IoT is the transfer of data over numerous different networks (WLAN, WAN, IP core, the cloud, etc.), each with their own distinctive protocol stacks and security mechanisms. Generally IoT-enabled devices (sensors, robots, etc.) need to connect to industrial networks using low power wireless connectivity technologies (like Bluetooth, 802.11, Z-Wave, etc.). It is, however, likely to be another 5 to 6 years before these will have IP capabilities. Standard transport layer security (TLS), which relies on IP, therefore cannot be applied.
Thanks to its partnership with embedded software specialist Ubiquios, plus related firmware support from Trusted Objects, Avnet Silica is ensuring that non-IP network vulnerability is fully addressed. A streamlined microcontroller stack has been developed through this cooperation, which forms the basis of the new IoT security reference design. The reference design is X509 certificate compliant, but this aspect has been rationalised, so that it respects the power and data limitations of Bluetooth 4.1 and other non-IP wireless protocols, while simultaneously being able to maintain the highest degrees of system security.
In addition, the reference design simplifies the provisioning of devices in the field (whether it is within an IP or non-IP context), making the procedure dramatically quicker to complete. Visit Avnet Silica at https://www.avnet-silica.com
