Maxim Integrated Products has announced the MAXREFDES143# embedded security reference design to address the many issues related to system security in IIoT installations. The reference design provides protection against counterfeit sensor data, guaranteeing its authenticity and integrity along the entire data chain, from transducer to the cloud.

The rapid growth of IoT capabilities for industrial applications comes with legitimate concerns about data integrity, due to deliberate corruption of critical sensor data anywhere between a source and the cloud. The reference design’s sophisticated architecture and components, Arduino-compatible hardware interface and ARM mbed libraries support simplifies development of secure, uncorrupted, and authenticated sensor-to-web data. It is suited for analogue sensor node and data authentication in factory automation and industrial processing applications.

The reference design’s two-stage hierarchical architecture consists of a shield that communicates to a web server and a protected sensor node for data acquisition and authentication. The shield includes a WiFi module; a DS2465 secure coprocessor for offloading SHA-256 cryptographic computation; 1-Wire and I²C interfaces; user-interface LCD, LEDs and pushbuttons; along with alarm and logging functions. The sensor node contains a DS28E15 secure authenticator, DS7505 temperature sensor and MAX44009 light sensor.

Scott Jones, Executive Director, Embedded Security, Maxim Integrated, commented: “The reference design is a powerful, much-needed tool for addressing the genuine issues of data security and authentication for Industrial IoT installations. The reference design combines the shield and sensor node to offer a solution with a high level of security and minimal development start-up effort and with low system-overhead burden.”

The MAXREFDES143# IoT embedded security reference design is available for $75.
