SDN-Based Double Hopping Communication against Sniffer Attack

Abstract EN

Sniffer attack has been a severe threat to network communication security.

Traditional network usually uses static network configuration, which provides convenience to sniffer attack.

In this paper, an SDN-based double hopping communication (DHC) approach is proposed to solve this problem.

In DHC, ends in communication packets as well as the routing paths are changed dynamically.

Therefore, the traffic will be distributed to multiple flows and transmitted along different paths.

Moreover, the data from multiple users will be mixed, bringing difficulty for attackers in obtaining and recovering the communication data, so that sniffer attack will be prevented effectively.

It is concluded that DHC is able to increase the overhead of sniffer attack, as well as the difficulty of communication data recovery.
