An Efficient Secure Sharing of Electronic Health Records Using IoT-Based Hyperledger Blockchain

Algorithm 1

Pseudocode of the MSSO algorithm.

	Set the salp population Hsi (i = 1, 2, …, n) as Cu and Cl
	While (end condition is not accomplished)
	Compute the fitness of each search agent equation (7)
	Da = the best search agent
	Modify Zwi by equation (4)
	For every salp (HSi)
	If (I = 1)
	Modify the position of the leading salp
	Else
	Modify the position of the follower salp by equation (5)
	End
	End
	Amend the salps based on the upper and lower bounds of variables
	End Return Da
