The Advanced Encryption Standard (AES) security modules provide hardware-accelerated data encryption and decryption operations based on a binary key. The AES is a symmetric cipher module that supports a 128-, 192-, or 256-bit key in hardware for both encryption and decryption. The AES module is based on a symmetric algorithm, meaning that the encryption and decryption keys are identical. To encrypt data means to convert it from plain text to an unintelligible form called cipher text. Decrypting cipher text converts previously encrypted data back to its original plain text form.

Application details

This application is a reference to usage of AES DriverLib functions on CC3200. Developers can refer to this simple application and re-use the functions in their applications.

aesdemo: This command allows the user to exercise the AES functionality on CC3200. The command needs two parameters:

User will be prompted for inputs for key and plain text input. User can also undefine USER_INPUT in main.c to use the default test vectors for debugging (psAESCBCTestVectors in main.c).

  1. Setup a serial communication application. Open a serial terminal on a PC with the following settings:
    • Port: Enumerated COM port
    • Baud rate: 115200
    • Data: 8 bit
    • Parity: None
    • Stop: 1 bit
    • Flow control: None
  2. Run the reference application.
    • Open the project in CCS/IAR. Build the application and debug to load to the device, or flash the binary using UniFlash.
  3. A prompt will appear on the terminal. Enter the aesdemo command with your chosen inputs as shown above.
