Content Summary | Recent advances in ambient, FM backscatter radio showed the feasibility of
piggybacking an audio signal on top of a broadcast FM radio transmission.
In conjunction with the weak transmission power inherent in backscatter ra-
dio systems, this work exploits FM ambient backscatter to achieve covert
communication. Information in the form of plain text is converted to a wide-
band audio signal using Direct Sequence Spread Spectrum (DSSS) modula-
tion, resulting in a noise-like audio signal undergoing Frequency Modulation
(FM) before being backscattered to a conventional smart phone equipped
with FM radio, acting as the receiver. A Linear Feedback Shift Register
(LFSR), provided with a key completely determining its output, generates
the symbol sequences that serve as spreading sequences in DSSS, thus adding
a Private-Key Encryption layer to enhance the cryptosystem's robustness. A
Repetition Code is utilized as a way of error correction to increase the per-
formance. Besides simulations, a prototype was implemented to verify the
feasibility of the proposed concept. | en |
