AES block ciper on AVR
One of the implementations is optimized for speed and achieves an encryption rate of about 103 kByte per second on a 16 MHz MCU. The other one is much smaller in size and achieves about 93 kByte per second. The decryption performs in both cases about 30%-40% slower than encryption.
