Abstract:
In this paper we describe a distortion-less network steganographic scheme for wireless multicast communications using MORE (MAC-independent Opportunistic Routing & Encoding) Protocol. An efficient implementation protocol that can run directly on top of 802.11 for wireless Random Linear Network Coding (RLNC) settings. To do so, we take advantage on a first hand, of the transfer matrix of the protocol (i.e. the random process managing the coefficients of the linear combinations), and on a second hand, of the ability of a sender node to change its transmission range at ease, and broadcast packets to all neighbouring nodes. Specifically, we use MORE’s transfer matrix as our covert channel, where we hide secret messages in each transmission phase.
