A security-enhanced routing algorithm with path randomization

Modern society is becoming increasingly dependent on various communication networks such as the Internet and the sensor networks. These networks need strong security measures to keep the traffic secure. If the security fails, many aspects of the society may suffer. In this paper, we address the network security challenge by focusing on one integral part of the network functionality: routing. Using Open Shortest Path First (OSPF) as our Internal Gateway Protocol (IGP), we aim to create a randomization process in which the packets will be sent through less predictable paths. By using this process we expect to increase the difficulty for a hacker to eavesdrop traffic hence improve network security.
