Attention-Based LSTM Model for IFA Detection in Named Data Networking

Algorithm 3

Hellinger distance-based malicious prefix recognition.

	Input:
	Interest prefix distribution when IFA is detected:
	Interest prefix distribution before IFA is detected:
	Interest prefix set:
	Output:
	Malicious prefix set
(1)
(2)	fordo
(3)
(4)	calculate the Hellinger distance
(5)	ifthen
(6)	add to malicious prefix set
(7)	end if
(8)	end for
(9)	return malicious prefix set
