Quantum Equivalence of the DLP and CDHP for Group Actions

Steven Galbraith and Lorenz Panny and Benjamin Smith and Frederik Vercauteren

Abstract: In this short note we give a polynomial-time quantum reduction from the vectorization problem (DLP) to the parallelization problem (CDHP) for group actions. Combined with the trivial reduction from parallelization to vectorization, we thus prove the quantum equivalence of both problems.
