Study of a new physical layer encryption concept
Ahmad Ahmad, Aroua Biri, Hossam Afifi · 2008
Physical layer encryption is taking a significant importance in securing wireless networks. In this paper, an efficient physical layer encryption is proposed. It relies on the implementation of OFB mode just after the error coding process. The significant advantage of this implementation is that it hides the entire Mac frame. In order to reduce the overhead power consumption at the receiver, an identification mechanism is presented. This security solution is valuable in terms of location privacy and attack prevention. The provided results in this paper prove that this solution does not have any influence on the encoder/decoder functionalities.
