Black-Box Composition Does Not Imply Adaptive Security
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...

Black-Box Constructions of Composable Protocols without Set-Up
Abstract. We present the first black-box construction of a secure multiparty computation protocol that satisfies a meaningful notion of concurrent security in the plain model (wi...

Constant-Round Multiparty Computation Using a Black-Box Pseudorandom Generator
We present a constant-round protocol for general secure multiparty computation which makes a black-box use of a pseudorandom generator. In particular, the protocol does not requir...

Composition Does Not Imply Adaptive Security
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...

Composition Implies Adaptive Security in Minicrypt
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...
