Cryptanalysis of three matrix-based key establishment protocols

Simon R. Blackburn, Carlos Cid and Ciaran Mullan

Abstract: We cryptanalyse a matrix-based key transport protocol due to Baumslag, Camps, Fine, Rosenberger and Xu from 2006. We also cryptanalyse two recently proposed matrix-based key agreement protocols, due to Habeeb, Kahrobaei and Shpilrain, and due to Romanczuk and Ustimenko.
