With the evolving Internet, two or more connected hosts may have access to numerous “Internet services” and nodes. However, they may-be impeded in some way from communicating directly or even indirectly with each other using the protocol of their choice.
This impedance could be:
- Intentional, such as the simple blocking of ports, to deep packet inspection leading to service downgraded or even blocking,
- Unintentional, from certain difficult-to-connect topologies. Such as where both hosts are on private networks behind a NAT.
By using a dynamic and seamless tunnelling approach, we can counter “traffic-hostile” networks to provide service-independent end-to-end connection through the Internet. Lucas will demonstrate the research he has taken out into traffic morphing and obfuscation.
He will cover the details of packet switching and a solution he has found using the Net filter kernel library, specifically the NFQUEUE table; allowing packets to be forked off to a program before they are sent to the network card for transmission.
Lucas graduated from the University of Chester in Nov 2014 with a 1st Class Honours in Computer Science, where he also worked as a part time Software Developer. He has worked in the IT Services department (LIS) since graduating as a Desktop and Network Infrastructure Technician.
His research interests include network traffic analysis and applied cryptography. He is currently studying an MPhil in the dept. of Computer Science.
