Lightweight Mutual Authentication Scheme Enabled by Stateless Blockchain for UAV Networks

Algorithm 1

UAV registers/builds the stateless blockchain.

	Input: Security parameters , UAV number , UAVs request.
	Output: Nodes’ ID vector commitment, trust value vector.
(1)	In Register Server:
(2)	#Received all UAVs’ requests
(3)	;  = {0};
(4)	crs = Setup ;
(5)	for in do# UAV nodes
(6)

(8)	;
(9)	;
(10)	end for
(11)	#Get the all registered UAVs identities:
(12)	#
(13)	, is randomnal;
(14)	#Randomly selects 5 UAVs from UAVs as the trusted committee
(15)
(16)	for all UAV nodes:
(17)	for uav_i in length of . do
(18)	, # is randomnal;
(19)	Send (, )
(20)	end for
(21)	#When receive genesis_block from register sever
(22)	if current_block is constructed correctly then
(23)	;
(24)	else
(25)	Abort Genesis block;
(26)	end if
