  • Publication number: 20200228567
    Abstract: Systems and method are provided for detecting Low Rate (LR) Denial of Service (DOS) Attacks, such as Shrew and New Shrew attacks, using spectral analysis and clustering algorithms. In an embodiment, the presence of suspicious low frequency periodic bursts due to Shrew or New Shrews attacks is detected during a specific time period using the aggregated traffic from multiple hosts. If low-frequency periodic bursts are suspected, clustering can be used to isolate suspicious hosts. After suspicious hosts are identified, a statistic test (e.g., a Fisher g-statistic test) for periodical content can be performed again on the traffic from each suspicious host to confirm the presence of a Shrew (New Shrew) attack and identify the offending host(s).

  • Publication number: 20130101059
    Abstract: A method for physical layer steganography communications is provided by combining an encoded cover data stream with a hidden data stream to create stego data stream. The cover and hidden data streams can be combined by determining an insertion rate, and determining, for each bit of the hidden data stream, whether to change an associated bit in the cover data stream. The bit of the cover data stream is changed to match the hidden data stream when the two bits are different. Otherwise, the cover data stream bit stays the same. The stego data stream can then be modulated and transmitted to a receiver. At the receiver, the stego data stream can be split to extract the hidden data stream, and the cover data stream can be decoded.
