Development and validation of a NS2 protocol for data security at network layer (original) (raw)

International Conference on Computing, Communication & Automation, 2015

Abstract

NS2 is an event-driven, object-oriented simulation tool to simulate and analyze the dynamic nature of communication networks; it is also a powerful tool to develop new protocols and functions. NS-2 is an open-source and very popular network simulation tool. It provides support for OSI or TCP/IP protocols stack and many standard routing and application protocols for wired and wireless networks. In NS2, many protocols have been implemented so far at the various layer of TCP/IP protocol suite to provide different functions, but none provides security functions. Although, some applications require security (Encryption/Decryption and key exchange) implementation in NS-2. However, NS-2 does not provide these features until now. In this paper, we solve this issue by adding a new security module or protocol in NS2. Security module helps us in key sharing as well as in the implementation of encryption/decryption functions. We analyze the features of a security module in details; discuss the algorithms used, simulation process and implementation of a security module based on NS2. Also, the simulation details of key sharing protocol and self-defined encryption/decryption protocol in a wired network are introduced. NAM is used to display the process of simulation. The purpose of the module is to introduce encryption/decryption features with key sharing into a network simulation program.
