Security Analysis on Blockchain-Powered Mobile APPs Connected with In-Vehicle Networks by Context-Based Reverse Engineering

Algorithm 2

Clustering (A).

	Input: semantic s = {s1, s2, …, s|s|}, cluster number k = {k1, k2, …, k|k|}
	Output: {c1, c2, …, c|k|}
(1)	repeat
(2)	x ← 1
(3)	//initial setting
	cx = {cx;1, …, cx;|o|} = {{s1}, …, {s|s|}}
(4)	repeat
(5)	//initial cluster merging
	(cα, cβ) =
	=,
(6)	New_c = cα ∪ cβ
(7)	cx = (cx\{cα, cβ}) ∪ {New_c}
(8)	until |cx| ≥ kx
(9)	x ← x + 1
(10)	until x > |k|
(11)	return {c1, c2, …, c|k|}
