... is S-Box content of Advanced Encryption Standard (AES) considered a part of Encryption Key?
i think it should be, not sure how law approaches this, however.
... this part of encryption key might be responsible for completion part of an Ecryption Algorithm, a private part of Encryption Algorithm.
public part of Encryption Algorithm is public key, private part should be considered a part of the key ... contributing to maximum of allowed encryption key bits.
... that's how i see this for now.
... this allows for AES extensions, for example - for optimizing encryption for certain conditions.
i think law allows for different key lengths for certain conditions, but i am not sure.
perhaps there's more to consider as well.
