MSFA: Multiple System Fingerprint Attack Scheme for IoT Anonymous Communication

Algorithm 2

Algorithm for getting the packet information.

(1) server_ips

(2) client_ips

(3) PROXYPORT_MIN

(4) PROXYPORT_MAX

(5) IF (Source address equals toclient_ips && Destination address equal toserver_ips

&& Source address port <= PROXYPORT_MAX

&& Source address port >= PROXYPORT_MIN

&& Destination address port <= PROXYPORT_MAX

&& Destination address port >= PROXYPORT_MIN)

(6) IF (Whether it is interrupted)

(7) IF (Destination address port <=PROXYPORT_MAX && Destination address port>=PROXYPORT_MIN)

(8) Packet length = -1

(9) Output packet length
