MAXREFDES143#

The MAXREFDES143# is a DeepCover embedded security in IOT authenticated sensing and notification. MAXREFDES143# subsystem reference design secures industrial IoT systems with hardware security provided by a DS2465 SHA-256 coprocessor and DS28E15 SHA-256 authenticator. In this IoT-embedded world, security emerges as a paramount feature to protect industrial equipment from counterfeiting while tracking product lifetime with smart notifications. It demonstrates an authenticated data chain from a protected sensor node to a web server. There are notifications to user through web server when intervention is required such as when it is time to change the consumable being monitored (i.e. protected sensor node), a filter in this case, or if an unsafe consumable (i.e. counterfeit sensor node) is installed. The simplicity of this design enables rapid integration into any star-topology IoT network requiring the heightened security with low overhead provided by SHA-256 symmetric-key algorithm.

• Unique secret for each node in the system
• DeepCover secure key storage
• 1-wire/I2C/Wi-Fi interfaces
• mbed shield equivalent to Arduino form factor pinout
• Pmod-compatible protected sensor node
• Crypto-strong authentication
• No need for secure key storage memory on processor
• Low overhead performance for signed data between the web server and the mbed platform
