This paper presents results of performance evaluation of NIST Lightweight Cryptography standardization finalists which are implemented by us. Our implementation method puts on the target to reduce RAM consumption on embedded devices. Our target microcontrollers are AVR ATmega 128 and ARM Cortex-M3. We apply our implementation method to five AEAD schemes which include four finalists of the NIST lightweight cryptography standardization and demonstrate the performance evaluation on target microcontrollers. From our performance evaluation of the RAM size, we have achieved 117-byte TinyJAMBU-128 on ATmega 128 and 140-byte TinyJAMBU-128 on ARM Cortex-M3. Our implementation of TinyJAMBU-128 has the smallest RAM of all the target AEAD schemes.
