Using Equivalence Classes to Accelerate Solving the Discrete Logarithm Problem in a Short Interval
The Pollard kangaroo method solves the discrete logarithm problem (DLP) in an interval of size N with heuristic average case expected running time approximately 2 √ N group opera...

Equivalences on Observable Processes
The aim of this paper is to find the finest `observable' and `implementable' equivalence on concurrent processes. This is a part of a larger programme to develop a theor...

Approximation of Natural W[P]-Complete Minimisation Problems Is Hard
We prove that the weighted monotone circuit satisfiability problem has no fixed-parameter tractable approximation algorithm with constant or polylogarithmic approximation ratio un...

Safe Equivalences for Security Properties
Abstract. In the field of Security, process equivalences have been used to characterize various information-hiding properties (for instance secrecy, anonymity and non-interference)...

Weak Equivalences in Psi-Calculi
Psi-calculi extend the pi-calculus with nominal datatypes to represent data, communication channels, and logics for facts and conditions. This general framework admits highly expr...
