@fgrieu it is interesting to see this from steganography perspective. i did not thought that way before !

comment Defining format-preserving encryption for natural language
good point , now lets define a "natural language" ? and the "formats" to preserve ?

very subjective and open ended question

comment What is the difference between various modes in FPE?
depends you need to pick on your requirements. you need greater range of lengths of formats or performance etc.

comment Attribute-based encryption for cloud storage
ABE scheme gives control over who can decrypt the ciphertext in the cloud (or any untrusted server) based on access policy (refer to KP-ABE , CP-ABE). Give us a reference of cloud storage to help you much better

comment Are there any noisy homomorphic encryption schemes?
Yeah fine by that, if the noise is not beyond $\epsilon$

comment Are there any noisy homomorphic encryption schemes?
@RickyDemer got it ! now the question left is whether there are natively noisy algorithms

@RickyDemer sorry i did not get you, can u be more clear ? what is a "just do it" construction ?

comment Why is a Feistel network not a type of substitution-permutation network?
Your question is not clear. A Feistel network could contain an SPN in its $f$ function but that is distinctly different from SPN itself

comment Epsilon Differential privacy using Laplace distribution
How did you prove individual mechanisms are preserver DP ? Why do you think you cannot prove the composition does not preserve ? give us more context to help you
