comment Authenticating Very Short (Sub-Block) Data
What if i dont want the tags for authentication and just the length preserving short block encryption is needed ? any suggestions apart from FPE techniques ?

comment Feistel cipher vs Substitution-permutation network - number of rounds
for feistel networks check "patarin's proof" , 7 rounds is what he proved to be good enough. i dont know about SPN

Oh yeah , i missed this key insight that the result is also cipher text.

comment “Practical” operations supported by functional encryption?
It sounded as if , Homorphic supports only those two operations. But they are the building blocks to support any other complex operations.

comment practically verifying block ciphers strength
yes the tools could be lot generic. Am imagining, machine learning based say "supervised learning" based techniques to identify non-randomness after some number of rounds etc.

comment practically verifying block ciphers strength
it is a encryption scheme not mode, shall correct it thanks ! BTW , curious what those tools are for analyzing "modes"

comment Homomorphic Encryption: how does the equality test on ciphertexts work?
@ChrisPeikert if encryption is randomized, i doubt if homomorphic properties are retained. For example RSA is multiplicative homomorphic only when padding is not used rite ? is there a catch some where am missing ?
