研究を始めるのに必要な知識・能力

We welcome students with abilities related to networks and network security who also have good computer programming and/or mathematical skills. Independent thinking and a strong motivation to learn and develop oneself are a must.

この研究で身につく能力

Students who graduate will have a deep knowledge of networks and network security. They will be able to develop network-related software and perform network experiments and assessments using various methods: analytical modeling, simulation, emulation and actual experimentation. Students will also gain hands-on network security experience; thus, they will be able to deal with cybersecurity issues in the real world. Their English paper reading/writing and presentation skills will also improve signifi cantly.

研究内容

People have become more and more reliant on the Internet for daily communication. In addition, networks are and will be more and more used to improve people’s quality of life in the context of smart homes, but also in the area of industrial automation. This will lead to a world in which devices and people are all connected to the same network, the Internet of Everything (IoE).

Cybersecurity

Although network communication makes life more convenient, it also exposes users to risks they must be aware of, such as malware, phishing, etc. As a consequence, the network applications people use, especially in mission-critical and safetycritical environments, need to be designed and analyzed from the perspective of such security risks. Furthermore, IT and security specialists must have the practical skills needed to be able to properly handle computer security incidents.

This knowledge can be acquired only partially through theoretical lectures, and it is of utmost importance to have practical experience with actual threats in order to be able to deal with them in an efficient and timely manner. This kind of experience can only be obtained in cyber ranges, realistic environments for cybersecurity training. For this purpose, we are developing an integrated cybersecurity training framework named CyTrONE that makes it possible to easily manage both the training content and the associated training environment.

Network emulation

In order to satisfy people’s needs, the pervasive network infrastructure of IoE demands guarantees regarding network performance, so that Quality of Experience (QoE) requirements are met. Network emulation is an experiment technique that enables carrying out the performance evaluations needed in this context, by recreating a wide range of network conditions, including emulated wireless networks and mobility.

研究室の指導方針

We aim at providing a dynamic environment in which students can increase their knowledge, learn new skills and develop new abilities. We lay a strong emphasis on applying theoretical knowledge in practice, and on hands-on experience with various aspects of networks and network security. Publishing and presenting one’s work are highly encouraged and supported.
