Project results evaluation
Following a two-year phase of exploration and validation of various forms of attribute value data representation and classification learning methods, we selected the best performing strategy consisting of data attributes computed from different-order entropies and chi-square statistics combined with the decision-tree classification strategy. This method was implemented in a command-line software tool, which was tested on audio data and generic network traffic data. The tests confirmed high accuracy of the method in recognizing compressed data streams from encrypted data streams.
