Classification: CPC G  H | IPC G  H

Claim 14:
15. A method comprising:
generating, by a hardware-implemented processor, a first randomness value fora data chunk of a plurality of data chunks using a multinomial distribution randomness test, wherein the plurality of data chunks form a stream of network traffic,
wherein when the first randomness value indicates that the data chunk is random, the method further comprises:
incrementing a stored accumulated randomness value corresponding to the data chunk without additional randomness testing of the data chunk, and

wherein when the first randomness value does not indicate that the data chunk is random, then the method configured comprises:
generating a second randomness value for the data chunk via a second randomness test that is different than the first randomness test,
wherein when the second randomness value indicates that the data chunk is random, then the method further comprises:
incrementing the stored accumulated randomness value corresponding to the data chunk without additional randomness testing of the data chunk,

aggregating, by the hardware-implemented processor, accumulated randomness values for each data chunk of the plurality of data chunks to generate an aggregated randomness value, and
identifying, by the hardware-implemented processor, the stream of network t raffic as random or not random based on a comparison of the aggregated randomness value to a threshold value.
