I've come across a form of cryptographic security that I've never heard of: entropic security. I've read the Russel et al abstract and that doesn't seem to bear much relation to the wiki article.
Things that confuse me are like:-
"Deterministic encryption" :A deterministic encryption scheme (as opposed to a probabilistic encryption scheme) is a cryptosystem which always produces the same ciphertext for a given plaintext and key, even over separate executions of the encryption algorithm.
That mode seems highly redundant as any 'proper' scheme would produce new cipher texts for repetitions of the same message (replay attack vs IVs?).
So what's entropic security for dummies, and how does the above fit in? I realise that Wikipedia is not the font of all knowledge.
