Robust symmetric key management techniques for next generation networks

Abstract

In the 21st century, wireless broadband technology is evolving through services and applications accessed at high speed, therefore, it is changing the way we live, work, and communicate. Wireless broadband communication has proven to be cost-effective, easy to access, fast, reliable and quick to deploy for applications and services. Nowadays, wireless newlinecommunication has become an important component of a network acting as a backbone for government sectors, large enterprises, telecom, military, universities, etc. The broadband wireless network is better than wireline in terms of cost, performance, and services with respect to deployment. Though, with the globe trending towards technologies such as 4th Generation (4G)/Long Term Evolution (LTE) and 5th Generation (5G), worries about security and lack of privacy protection should not turn as a barrier for adoption of Next Generation Networks (NGN). Though wireless broadband technologies aim to provide last mile connectivity, end-to-end security is needed at all levels of communication. Since most of the wireless technologies are based on shared Radio Frequencies (RF), the chance for intrusion is high when compared to wired deployments. Hence, securing the end users and protecting the network resources are the most interesting challenges for researchers and service providers in NGN. In NGN, privacy theft, Denial of Service (DoS) and Manin- the-Middle (MitM) attack are the major security challenges need to be addressed in order to benefits the end users. Confidentiality, integrity, and availability are the main goals of security solutions to protect the end user privacy. To overcome the existing network security issues and to protect system for future attacks, a secure framework for NGNs is required. newline newline
