An Add-on for Security on Concurrent Multipath Communication SCTP

Multi-homing is a mechanism that ties one transport layer association to several network interfaces, which provides a base to exchange data over several network paths. Concurrent Multipath Communication for Stream Control Transmission Protocol (CMC-SCTP) was developed by us for simultaneous data transmission over multiple paths increases path throughput and network interface failover. In this paper, we introduced a method to exchange encrypted data between two end nodes on base of multipath data transmission without any pre-shared key arrangement. This can efficiently increase connection security for the nodes that they can communicate over two or more independent paths. Our method not only protects data against the attacker, who can sniff out the transmitted data over the communicating paths but also increases the node data transfer rate. An OPNET simulation demonstrates and evaluates the efficiency of our proposed mechanism.
