The Anshel-Anshel-Goldfeld-Lemieux (abbreviated AAGL) key agreement protocol is proposed to be used on low-cost platforms which constraint the use of computational resources. The core of the protocol is the concept of an Algebraic Eraser (abbreviated AE) which is claimed to be a suitable primitive for use within lightweight cryptography. The AE primitive is based on a new and ingenious idea of using an action of a semidirect product on a (semi)group to obscure involved algebraic structures.

In this paper we revisit the computational problem on which AE relies and heuristically analyze its hardness. We show that for proposed parameter values it is impossible to instantiate the secure protocol. To be more precise, in 100% of randomly generated instances of the protocol we were able to find a secret conjugator z generated by TTP algorithm (part of AAGL protocol).
Abstract.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 monoids. We devise a practical heuristic algorithm solving those problems. As a conclusion we claim that these protocols are insecure for the proposed parameter values.doi:10.1515/jmc-2012-0033 fatcat:twuihiimdreoncwfocyhnke4oa

The length based attack on Anshel-Anshel-Goldfeld commutator key-exchange protocol  was initially proposed by Hughes and Tannenbaum in  . Several attempts have been made to implement the attack , but none of them had produced results convincing enough to believe that attack works. In this paper we show that accurately designed length based attack can successfully break a random instance of the simultaneous conjugacy search problem for certain parameter values and argue that thedoi:10.1007/978-3-540-71677-8_6 dblp:conf/pkc/MyasnikovU07 fatcat:uo6z55bxgfh27lnp5j7pjulnle
