Algorithm	Computational Costs
	P/T	D/E/D	C/S
Algorithm 1	$\left|\mathrm{P}\right|=\left|p_1\left|+\right|p_2\right|+\dots$ $+\left|p_n\right|$	|P| = |n|	$\left|P^{\prime }\right|$ = |n|
Algorithm 2	|HTTP| + |TCP|	|TF|	|MTF|
Algorithm 3	$\left|\mathrm{B}\right|=\left|B_1\left|+\right|B_2\right|+\dots$ $+\left|B_n\right|$	$\left|\mathrm{I}\right|+\left|S{S}_1\left|+\right|S{S}_2\right|$	$\left|S{S}_1\left|+\right|S{S}_2\right|$
Algorithm 4	|T| + |I| = |n|	$\left|T^{\prime }\right|+$$\left|I^{\prime }\right|$= |n|	|PF|

P/T, packets/tokenize; D/E/D, decryption/extraction/decomposed, TF, trained feature; MTF, mining trained files; C/S, computes/shifting.
