MSP432 vs MSP430 for communication encryption

rashevskiy
By rashevskiy in General,
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 data to controller (via discrete output). So, I need MCU with hardware accelerated AES, LaunchPad kit and Energia IDE support. From MSP portfolio I have chosen two models: MSP432P401R and MSP430FR5994 (MSP430FR5969 and MSP430FR6989 also meet my criteria). What is the best solution suitable for me and my goal? Thank you for your help!
