To Improve Security and Performance in the NGN

Abstract

The common thought about Next Generation Network (NGN) is that one system transports all data and
services like information, voice and video by enclosing these into packets on the Internet. Transport Layer Security (TLS)
protocol provides a secure transmission between communicating applications and their users on the internet. It gives
security with some encryption method such as Advanced Encryption Standard (AES). This paper presents a security and
performance for data transmission in 3G/4G networks using TLS. Here AES 128 bit is used for encryption because of its
high efficiency and ease. AES is modified by using permutation instead of the mix column to overcome the problem of
high calculation and computational overhead. The system is further enhanced by parallel AES to improve the speed of
the algorithm. In parallel computing, functions of AES are divided into two independent parts. Comparison is made
between traditional AES and enhanced system on the basis of performance. Evaluation is based on Encryption Time,
Decryption Time and Throughput.
