Modern Crypto Systems in Next Generation Networks

Abstract

The performance of Next Generation Networks (NGN) in terms of security, speed, synchronization, latency, and throughput with variable synchronous or asynchronous packet sizes has not been sufficiently addressed in novel crypto systems. Traditional crypto systems such as block and stream ciphers have been studied and implemented for various networks such as wire line and wireless systems. Since NGN comprises of wire line and wireless networks with variable packet-based communication carrying various traffic like multimedia, video, audio, multi conferencing, and a large amount of data transfers at higher speeds. The modern crypto systems suffer with various challenges such as algorithm implementation, variable packet sizes, communication, latency, throughput, key size, key management, and speed. In this chapter, the authors discuss some of the important issues and challenges faced by modern crypto systems in Next Generation Networks (NGN) such as algorithm implementation, speed, throughput and latency in communication, point-to-multipoint, broadcast and key size, remote key management, and communication speed.
