Machine-To-Machine (M2M) networks are spreading over every sector of the people society due to their self-organization capabilities. In these networks, thousands of devices are left unattended for years of operation without the possibility of human intervention and thus, security issues must be addressed in order to ensure reliable communications. Due to the limited capabilities of M2M devices and the wireless communications settings, Denial of Service (DoS) attacks constitute one of the major threats, and still require further attention from the scientific community. The authors introduced a novel security scheme which was shown to yield enormous benefits with regard such attacks by making use of an Authentication Preamble (AP) at the PHY-layer.
