I have been studying and researching hash functions. So far my research has led me to the sponge construction. It appears that the permutation used in the sponge to stir the state is more or less ...
Is it safe to XOR parameters like domain, length of the message or block counter into sponge's capacity or that gives attacker control over capacity? For example NORX XORs domain into capacity. Does ...
The sponge construct facilitates authenticated encryption independently of the function used to mix its state. Could we use any strong cipher (i.e. AES-256) as the mixing function in a sponge to ...
