Several research groups are working on designing new security architectures for 4G networks such as Hokey and Y-Comm. Since designing an efficient security module requires a clear identification of potential threats, this paper attempts to outline the security challenges in 4G networks. A good way to achieve this is by investigating the possibility of(More)
In recent years, there has been a huge trend towards running network intensive applications, such as Internet servers and Cloud-based service in virtual environment, where multiple virtual machines (VMs) running on the same machine share the machine's physical and network resources. In such environment, the virtual machine monitor (VMM) virtualizes the(More)
Security for Next Generation Networks (NGN) is an attractive topic for many research groups. The Y-Comm security group believes that a new security approach is needed to address the security challenges in 4G networks. This paper sheds light on our approach of providing security for the Y-Comm architecture as an example of 4G communication frameworks. Our(More)
The development and deployment of several wireless and cellular networks mean that users will demand to be always connected as they move around. Mobile nodes will therefore have several interfaces and connections will be seamlessly switched among available networks using vertical handover techniques. Proactive handover mechanisms can be combined with the(More)
Communications in Information-Centric Networking place more attention on WHAT data are being exchanged rather than WHO are exchanging them. A well-established approach of information centric networks is the Network of Information (NetInf) architecture, developed as part of the EU FP7 project SAIL. The security of NetInf has been fairly analysed in the(More)
Recent advances in mobile devices and network technologies have set new trends in the way we use computers and access networks. Cloud Computing, where processing and storage resources are residing on the network is one of these trends. The other is Mobile Computing, where mobile devices such as smartphones and tablets are believed to replace personal(More)
Next generation networks will comprise different wireless networks including cellular technologies, WLAN and indoor technologies. To support these heterogeneous environments, there is a need to consider a new design of the network infrastructure. Furthermore, this heterogeneous environment implies that future devices will need to roam between different(More)
The Next Generation Internet will provide ubiquitous computing by the seamless operation of heterogeneous wireless networks. It will also provide support for quality-ofservice, QoS, fostering new classes of applications and will have a built-in multi-level security environment. A key requirement of this new infrastructure will be support for efficient(More)
