Constant-Round Non-malleable Commitments from Sub-exponential One-Way Functions
We present a constant-round non-malleable commitment scheme based on the existence of sub-exponential one-way functions and using a blackbox proof of security. As far as we know, t...

Construction of a Non-malleable Encryption Scheme from Any Semantically Secure One
There are several candidate semantically secure encryption schemes, yet in many applications non-malleability of encryptions is crucial. We show how to transform any semantically s...

An Oracle Strongly Separating Deterministic Time from Nondeterministic Time, via Kolmogorov Complexity
Hartmanis used Kolmogorov complexity to provide an alternate proof of the classical result of Baker, Gill, and Solovay that there is an oracle relative to which P is not NP. We re...

Reflecting Proofs in First-Order Logic with Equality
Our general goal is to provide better automation in interactive proof assistants such as Coq. We present an interpreter of proof traces in first-order multi-sorted logic with equal...

Proof Terms for Simply Typed Higher Order Logic
Abstract. This paper presents proof terms for simply typed, intuitionistic higher order logic, a popular logical framework. Unification-based algorithms for the compression and re...
