To prove that a secure key-agreement protocol exists one must at least show P = NP. Moreover any proof that the sequential composition of two non-adaptively secure pseudorandom fun...
In trying to provide formal evidence that composition has security increasing properties, we ask if the composition of non-adaptively secure permutation generators necessarily pro...
We study the question whether the sequential or parallel composition of two functions, each indistinguishable from a random function by non-adaptive distinguishers is secure agains...
We investigate the question of whether security of protocols in the information-theoretic setting (where the adversary is computationally unbounded) implies the security of these ...
