AES using a key of 320 bit length
Posted in the Cryptography Forum

I want to develop an AES encryption using a key with 320 bits.
And all the examples I have been seen, they use a table ok key round combinaison, for the example
K len Block size Number of rounds
AES-128 4 4 10
AES-192 6 4 12
AES-256 8 4 14
So I didn't find the rule to establish the number of round key for 320 bits key length

Take a look at the section 12 of the version 2 of the aes proposal (the ammended version).
Nr = max(Nk,Nb)+6
Would be an AES-320 a "10,4,16"?
