Group Theory 2020-10-19 v1

Abstract

We propose new provable practical deterministic polynomial time algorithm for the braid Wang, Xu, Li, Lin and Wang Double shielded public key cryptosystems. We show that a linear decomposition attack based on the decomposition method introduced by the author in monography "Algebraic Cryptography" (2013) and some papers works for the image of braids under the Lawrence-Krammer representation by finding the exchanging keys in both two main protocols by the authors listed above.
