Launch of Industrial IoT Data Security Solution 'MAXREFDES143#'
Secure 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.
