A New Mode of Encryption Providing a Tweakable Strong Pseudo-random Permutation
We present PEP, which is a new construction of a tweakable strong pseudo-random permutation. PEP uses a hash-encrypt-hash approach which has recently been used in the construction...

Unconditional pseudorandom generators for low degree polynomials
Abstract: We give an explicit construction of a pseudorandom generator against lowdegree polynomials over finite fields. Pseudorandom generators against linear polynomials, known...

Satisfiability Decay along Conjunctions of Pseudo-Random Clauses
Abstract. k-SAT is a fundamental constraint satisfaction problem. It involves S(m), the satisfaction set of the conjunction of m clauses, each clause a disjunction of k literals. T...

Step Indexed Realizability Semantics for a Call-by-Value Language Based on Basic Combinatorial Objects
—We propose a mathematical framework for step indexed realizability semantics of a call-by-value polymorphic lambda calculus with recursion, existential types and recursive types...

A Latency-Free Election Scheme
We motivate and describe the problem of finding protocols for multiparty computations that only use a single broadcast round per computation (latency-free computations). We show t...
