Lightweight Mutual Authentication Scheme Enabled by Stateless Blockchain for UAV Networks

Algorithm 3

Third subvector commitment.

	Input: Identities VC, , related uav ID.
	Output: Aggregation of the uncontacted UAVs’ proof.
(1)	In UAV node:
(2)	;
(3)	= 10 s,  = 0;
(4)	#watchdog in UAV observes neighbors’ behaviors,
(5)	#uavs locally analysis
(6)	#send the misbehavior to the current committee.
(7)	while 1 do

(9)	ifthen
(10)	#create untrust transaction

(14)	end while
(15)	In Committee members:
