Cryptanalysis of matrix conjugation schemes
In this paper we cryptanalyze two protocols: the Grigoriev–Shpilrain authentication protocol and a public key cryptosystem due to Wang, Wang, Cao, Okamoto and Shao. Both of these protocols use the computational hardness of some variations of the conjugacy search problem in a class of noncommutative...
