Abstract
Worldwide, the Long Term Evolution Advanced technology has an unprecedented development and popularization in recent years. With the advantages of mobile communication technology, more and more researchers are focused on the security of mobile communication. Until then, some researches about covert channels over the 4th generation mobile communication technology had been proposed. Cantor Expansion is a permutation to a bijection of natural number, so it can be used as a coding scheme for a covert channel. In this paper, a novel class of covert channel based on Cantor Expansion (for decoding) and its inverse operation (for encoding) is proposed and designed for this mobile network. The description, analyses and evaluation of this covert channel will be present in the main part of this paper. Moreover, the peak value of camouflage capability can reach 1470 kbps. Nevertheless it doesnt affect the bandwidth of overt channel and it is difficult to be detected.
