A Subexponential Quantum Algorithm for the Semidirect Discrete Logarithm Problem
Christopher Battarbee, Delaram Kahrobaei, Ludovic Perret +1
Group-based cryptography is a relatively unexplored family in post-quantum cryptography, and the so-called Semidirect Discrete Logarithm Problem (SDLP) is one of its most central p…
