Hello! In my own automation system I have to encrypt data transferred between sensor and main controller (data transfers via twisted pair). For this reason, I need a special devices - encryption gateways (one gateaway installs on sensor-side, another on controller-side). These gateways realize following algorithm: Sensor-side: Receive some data from sensor (via discrete input); Encrypt data using AES; Transfer encrypted data to controller-side gateway. Controller-side: Receive encrypted data from sensor-side gateway; Decrypt data; Transfer
The feature list for the redbear cc3200 includes a hardware crypto engine with aes functionality. I am having a hard time figuring out how to access those libraries. Can someone point me in the right direction or perhaps to an example of usage?
