Highly secure coprocessor supports Arduino and ARM mbed platforms, assures easy prototyping
Addressing the many issues related to system security in Industrial Internet of Things (IIoT) installations, the MAXREFDES143 embedded security reference design from Maxim Integrated Products, Inc. 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 ideal for analog 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 Wi-Fi 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.
The MAXREFDES143 IoT embedded security reference design is available for $75 at Maxim's website and select franchised distributors. Hardware and firmware design files are free and available online.
