You have to also keep in mind,aes is class-b crypto, the only publicly known class-a ciphers are decades older than aes.
- alephnil 7y agoThe sbox is a part of the definition of AES. If you change it it is no longer AES, and the new algorithm (that may well have vulnerabilities) is no longer compatible with the cryptographic protocols that specifies that they use AES as a cipher.
