BFLP: An Adaptive Federated Learning Framework for Internet of Vehicles

Algorithm 6

CPC encryption process.

	Input: M, Kenc
	Output: C
	1: Divide M ⟶ M1, M2, M3,M4
	2: Generate different Keyj form the main Key Kenc
	3: for each round j = 1 : 8 do
	4:     X := MjMj + 1
	5:     Y := Mj + 1Mj + 3
	6:     Count1 := Count − Zero (X)
	7:      W := f1 (Count1, X)
	8:      R := WY
	9:     Count2 := Count − Zero (R)
	10:       S := f2(Count2, R)
	11:       Mj+4 := S
	12:  Permutation: (Mj + 1, Mj + 2,Mj + 3)
	13: end for
	14: C := M9||M10||M11||M12
	15: Output C
