Maxim’s New IIoT Reference Design Securely Develops Sensor-to-Web Data

MAXREFDES143

Maxim Integrated Products introduces MAXREFDES143# embedded security reference design to address critical issues in the system security of Industrial Internet of Things (IIoT) installations. Powered by sophisticated architectures and components like Arduino-compatible hardware interface, and ARM mbed libraries support – the new reference design eases development of secure, uncorrupted, and authenticated sensor-to-web data.

It is also sought to protect against counterfeit sensor data, guaranteeing its authenticity and integrity along the entire data chain, from transducer to the cloud.

Key Advantages

  • Fast Time-to-Market: Significantly reduces development time using the provided hardware and source code to implement an authenticated node solution and web server interface
  • Ease-of-Use: Free evaluation web server provides an immediate out-of-the box implementation for real-time data collection and storage of sensor data
  • Secure: SHA-256 coprocessor offloads data authentication task; securely stores node authentication key; each node has a unique key

Citing on the new roll out, Scott Jones, Executive Director, Embedded Security, Maxim Integrated said, “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.”

“Enabling robust security and data integrity is critical to the continued adoption of IoT solutions,” said Michael Horne, Vice President of Marketing and Sales, IoT Business, ARM. “The MAXREFDES143# simplifies testing with ARM mbed-compatible development boards, allowing designers to rapidly develop resilient industrial IoT platforms.

Additionally, the reference design’s two-stage hierarchical architecture is known to consist 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.

Availability and Pricing

  • 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.
