Cryptanalysis of the Anshel-Anshel-Goldfeld-Lemieux Key Agreement Protocol

The Anshel-Anshel-Goldfeld-Lemieux (abbreviated AAGL) key agreement protocol [1] 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. The underlying motivation for AAGL protocol is the need to secure networks which deploy Radio Frequency Identification (RFID) tags used for identification, authentication, tracing and point-of-sale applications.
