Maxim Unveils Reference Solution for Industrial IoT Data Security Authentication
Published2016.08.30 10:03Secure Coprocessor Supports Arduino and ARM mbed Platforms
Maxim Integrated Products Korea (CEO Hyunsik Kim) announced the 'MAXREFDES143#' embedded security reference design that addresses security issues in industrial Internet of Things (IoT) systems.
MAXREFDES143# protects the system from counterfeit sensor data and ensures the authenticity and integrity of the entire data chain from transducer to cloud.
As IoT capabilities in industrial applications proliferate, data integrity concerns are growing due to deliberate corruption of critical sensor data between the source and the cloud. The MAXREFDES143# reference design simplifies the development of secure, authenticated data transmitted from sensors to the web with its sophisticated architecture and components, Arduino-compatible hardware interface, and ARM mbed library support. It is ideal for analog sensor nodes and data authentication in factory automation and industrial applications.
The two-tier architecture of the MAXREFDES143# reference design consists of a 'Shield' that communicates with the web server and secure 'sensor nodes' that collect and authenticate data. The shield includes a Wi-Fi module, a DS2465 coprocessor that offloads SHA-256 cryptographic operations and securely stores each node's unique authentication key, a 1-wire, I2C interface, a user interface LCD LED, push buttons, alarms, and logging capabilities.
The sensor node consists of a secure DS28E15 authenticator, a DS7505 temperature sensor, and a MAX44009 light sensor. The evaluation web server collects real-time, readily available data and stores the sensor data.
“The MAXREFDES143# reference design is a powerful tool to address data security and authentication challenges in industrial IoT installations,” said Scott Jones, executive director of Embedded Security at Maxim Integrated. “By integrating the shield and sensor node, it provides a solution that delivers high security while minimizing development time and reducing system cost.”
“Robust security and data integrity are critical when deploying IoT solutions,” said Michael Horne, vice president of marketing and sales, IoT Business Unit, ARM. “The MAXREFDES143# simplifies testing ARM mbed-compatible development boards, enabling designers to quickly develop industrial IoT platforms.”
The MAXREFDES143# IoT Embedded Security Reference Design is available for $75 from Maxim's website and distributors. Hardware and firmware design files are available online free of charge.

Urgent need to embrace changes in smart production through the utilization of industrial IoT
In the utilization of Industrial Internet of Things (IIoT), which serves as the foundation for realizing smart factories, manufacturers' preparedness has been insufficient, indicating that a paradigm shift in awareness regarding smart production is urgently needed. Industrial Internet of Things is being utilized in the manufacturing industry for process optimization and production efficiency improvement, and is expanding to other industries overseas. With the digitalization of manufacturing, IoT technology is being integrated into traditional production processes, with cost reduction and productivity improvement becoming increasingly evident. Industrial Internet of Things, which connects various physical and virtual objects based on the Internet, refers to the collective infrastructure that is utilized in equipment, manufacturing, logistics, and distribution to support intelligent supply chains from a manufacturing perspective and demand-driven production from a sales perspective, and provides various services to enhance industrial efficiency accordingly. Accordingly, it comprises services, devices, and platforms, and through the provision of connectivity among each component, all elements of equipment, manufacturing, distribution/logistics, and services interoperate with one another, providing high value-added creation in the smart manufacturing sector based on this foundation.

Smart factories become even smarter as ‘industrial Ethernet’ spreads rapidly
As smart factories have become a major issue following manufacturing innovation, interest in industrial network technologies has been growing. Regarding industrial network technology, industrial Ethernet is currently expanding rapidly in wired communication, while in the wireless communication field, technology based on 802.11 is mainly being utilized for monitoring purposes rather than control applications. First, in industrial wired communication, industrial Ethernet technology that takes into account the strengths of both existing Fieldbus and general Ethernet is spreading. Fieldbus is an industrial communication technology widely used because of its advantages in wiring convenience and small data processing capability, and above all, it is a proven technology in terms of cost competitiveness. However, it has drawbacks including insufficient communication media and compatibility, inability to respond to increasing application requirements, speed limitations (12~16Mbps), and weak implementation of redundancy functions.
