Why does AES has exactly 10 rounds for 128 bit key, 12 for 192 and 14 for 256 bit key size
I was reading AES algorithm to be used in one of our projects and found that there are exact number of rounds fixed in AES for specific key sizes.
128 bit key size -> 10 rounds
192 bit key size -> 12 rounds
256 bit key size -> 14 rounds
Why these specific number of rounds only ?
128 bit key size -> 10 rounds
192 bit key size -> 12 rounds
256 bit key size -> 14 rounds
Why these specific number of rounds only ?
Because when Rijndael was developing it, he tried different rounds to see what produced the best results. What you see is it.
Got it Duthomhas, seems to be a statistical result which provides secured encryption and optimal performance.
