PRESENT_AVR

Optimized Implementation of PRESENT on 8-bit AVR (ATmega128)

Test vectors for PRESENT with an 80-bit key

plaintext = 00000000 00000000

key = 00000000 00000000 0000

ciphertext = 5579c138 7b228445

This code encrypts after pre-calculating the KeySchedule and the P operation performed on some round keys. PRESENT-80 and PRESENT-128 have the same number of rounds (and the same number of round keys), so if you pre-calculate the round keys, you can use this encryption function for each mode.
