Modifying The Tropical Version of Stickel’s Key Exchange Protocol

Any Muanalifah and Serge˘ı Sergeev

Abstract

A tropical version of Stickel’s key exchange protocol was suggested by Grigoriev and Sphilrain [2] and successfully attacked by Kotov and Ushakov [5]. We suggest some modifications of this scheme that use commuting matrices in tropical algebra and discuss some possibilities of attacks on these new modifications. We suggest some simple heuristic attacks on one of our new protocols, and then we generalize the Kotov and Ushakov attack on Stickel’s protocol and discuss the application of that generalised attack to all our new protocols
