HOW SOC PROGRAMMABLE PLATFORMS DRIVE THE CHANGE The “magic” of merging high-end networking, powerful processing and sensing capabilities has been obtained thanks to SoC programmable platforms. Our product, named CPPSGate40, embeds a Xilinx Zynq-7000 All Programmable SoC device implemented on the SoC-e SMARTzynq OEM module. The dual- core ARM® Cortex™-A9 MPCore™ on the device is complemented with different memory resources (DDR3, flash, massive storage units, etc.) and hardware to support multiple high-speed networking links. This infrastructure offers a huge level of freedom to partition hardware and software processing in order to face the

network and user point of view, it is necessary to secure three network links—the redundant HSR/PRP, the 10/100/1G switching port and the service ports—with authentication mechanisms. Furthermore, due to all the plant traffic passing through the intelligent gateway, the three links will play a vital role in monitoring traffic for potential threats. A final concept is the integration of a sensor interface suite. As discussed, the advances in the technology should help us to simplify the installations, not make them more complex. To fulfill this demand, we integrated all the standard digital and analog interfaces in the gateway. Additionally, we also included high-end interfaces for advanced vibration sensors and high- speed data acquisition interfaces with direct access to the Zynq SoC device.

use many of the solutions present in the IT world today. Well-known authentication mechanisms like IEEE 802.1X combined with RADIUS are a good example. Many embedded systems with high-level operating systems can run cryptographic libraries (such as OpenSSL) to support all the secure Layer 3 protocols and applications useful for secure data interchange. However, a big challenge arises when it is necessary to secure Layer 2 industrial protocols with strict real-time requirements. The analysis of these scenarios shows that the software approach of protecting these frames by applying cryptographic algorithms, even using crypto accelerators, is not straightforward, and in many cases custom hardware processing is required.
