MAXIM INTEGRATED PRODUCTS  MAXREFDES143#  REF DESIGN BRD, EMBEDDED SECURITY IN IOT 新

The 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.
