Abstract

Covert channels are not a new topic. However they remain an interesting research area. The most proposed techniques are located in the upper layers of the OSI model. In this paper, we present a new covert channel in the data link layer dedicated to wireless local area networks. It uses either sequence control or initial vector fields or both of them depending on the configuration of the network. We present also some measurements to protect the proposed channel against steganalysis and sniffing.
