We analyze several recent schemes for watermarking network flows based on splitting the flow into intervals. We show that this approach creates time dependent correlations that en...

Abstract. Scaling attacks are well-known to be some of the most harmful strategies against quantization-based watermarking methods, as they desynchronize the decoder, completely ru...
