Performance-optimized AES Implementation for Renesas RL78 Microcontroller

For RL78 microcontrollers we offer a performance and code-size optimized AES implementation. The implementation is written and optimized in assembly and provides a simple interface implemented in C.

  • Functionality:
    • AES-128 encryption and decryption in ECB or CBC mode
    • On-the-fly roundkey generation
    • Automatic decryption key calculation
  • Performance:
    • AES-128 encryption in ECB mode in 3112 instruction cycles
    • AES-128 decryption in ECB mode in 4872 instruction cycles
    • AES-128 encryption in CBC mode in 3380 instruction cycles
    • AES-128 decryption in CBC mode in 5266 instruction cycles
  • Codesize:
    • Codesize for AES-128 ECB mode is 2140 bytes
    • Codesize for AES-128 CBC mode is 2227 bytes
  • Fully documented source code
  • Documentation including architecture and interface description
