AONT - Based Packet Hiding Method for Preventing Jamming Attacks

Wireless networks now enjoy widespread commercial implementation because of their ease of use, low cost and setup. However, since accessing wireless media is much easier than tapping a wired network, then security becomes a serious concern when implementing any wireless network. We consider a particular class of Denial of Service (DoS) attacks called jamming attacks. In the simplest form of jamming, the attacker interferes with the reception of messages by transmitting a continuous jamming signal, or several short jamming pulses. Jamming results in the loss of link reliability, increased energy consumption, extended packet delays and disruption of end-to-end routes. The use of distinct, dedicated communication links to transmit data and control traffic introduces a single point of failure for a denial of service attack, in that an adversary may be able to jam control channel traffic and prevent relevant data traffic. To prevent such jamming attacks, in this paper we propose a packet hiding method based on allornothing transforms (AONT).
