On the Construction of Pseudo-Random Permutations: Luby-Rackoff Revisited

Luby and Rackoff showed a method for constructing a pseudo-random
permutation from a pseudo-random function. The method is based on
composing four (or three for weakened security) so called Feistel
permutations each of which requires the evaluation of a pseudo-random
function. We reduce somewhat the complexity ... more >>>

Zaps and Their Applications

A zap is a two-round, witness-indistinguishable protocol in which
the first round, consisting of a message from the verifier to the
prover, can be fixed ``once-and-for-all" and applied to any instance,
and where the verifier does not use any private coins.
We present a zap for every language in NP, ... more >>>
