    Human aspects are key factors when designing new privacy-enhancing technologies

    As Internet use has increased in society, risks related to privacy online have also become more important. Researchers have developed new technologies to protect the privacy of users, but many people are unaware or choose not to use them. In a doctoral dissertation, Ala Sarah Alaqra has investigated why using privacy protection technologies is complex even though they are available.

    “Data is the new currency in this time and age and most people say that online privacy is important to them, but their behavior sometimes indicate the contrary,” says Ala Sarah Alaqra. As a researcher in the field of privacy protection, I want to find out why this is so, explore different factors, incentives, and trade-offs that affect the eco-system of data privacy, so that we can eventually be able to aid users in accepting and adopting new technologies that can protect their personal privacy online.

    A new function in the intrusion detection system SNORT makes multipath networks safer

    You have probably noticed that an online video clip playing on your mobile phone is interrupted when you leave your house and the Wifi network. The mobile phone connects to 4G, and the video clip resumes. One advantage of multipath networks, which will be common in the future, is that your mobile phone will switch between different networks without you noticing it. Your connection will be really fast when traffic is distributed across several paths, but at the same time the risk of intrusion increases. Zeeshan Afzal, who recently completed a Degree of Doctor in Computer Science, focused his doctoral studies on the security challenges of multipath networks.

    “My research is about the protocol ”Multipath TCP”, a new network language that our connected devices might use to communicate in the future,” says Zeeshan Afzal. “My focus has been to teach security systems to understand this language, which will enable them to detect security problems such as intrusion attempts.”

    Programmable networks offer increased flexibility without a loss of performance

    New applications such as autonomous cars, robot surgery, and the next generation automation and manufacturing technologies demand ever more flexibility and capacity in computer networks. Jonathan Vestin, who recently completed a Degree of Doctor in Computer Science, has investigated how programmable networking can be used to supply the flexibility that is required.

    “The areas of Internet use are increasing all the time, and new applications such as for instance autonomous cars and robot surgery place new demands on the reliability and speed of networks,” says Jonathan Vestin. “At the same time, there are attempts to organise the Internet in such a way that different types of traffic can co-exist. This requires flexibility and an ability to prioritise critical traffic over ordinary traffic.”

    A new project will build the next generation of programmable networks

    Programmable networks can be developed in many different aspects, for instance when it comes to better performance, increased control of the network, and improved security. In a new project at Karlstad University, researchers in Computer Science collaborate with the IT company Red Hat to develop new solutions for programmable networks based on open software.

    Programmable networks enable developers to write programs that process all data packets that are sent over the network in real-time. These programs can for instance analyse data traffic in order to distribute the load across different servers, but also in order to protect the network against attacks.

    Simone Fischer-Hübner appointed honorary doctor at Chalmers University of Technology

    “I’m very pleased and honoured,” says Simone Fischer-Hübner, professor of computer science at Karlstad University. “Privacy and cyber security play an increasingly important role in society, so this honorary distinction is especially significant. I’ve always appreciated working with the IT-security researchers at Chalmers, and I hope that we can strengthen the collaboration further and contribute to advancing research together.”

    Simone Fischer-Hübner receives her honorary doctorate for her outstanding contribution to research on privacy-enhancing technologies and her engagement in the privacy agenda in the society at large.The honorary doctorate recognizes her central role in the Swedish and international research activities and networks in security and privacy, cross-disciplinary areas that are strategically important at Chalmers.

    Simone will receive the title at Chalmers doctoral promotion, 6 June.

    Prestigious prize to Computer Science Professor

    Javid Taheri, a professor of Computer Science at Karlstad University, has received the “Award for Excellence” by the IEEE Technical Committee on Scalable Computing (TCSC). He was presented with this award for his contributions on cloud computing and use of artificial intelligence to optimise highly distributed cloud-based scalable systems.

    “I’m very happy to receive this award. It motivates me to work even harder and hopefully have more impact on this field as well as those related to it,” says Professor Javid Taheri.
    The prize is awarded based on publications and successful applications for research funds, among other things, and is given each year to three individuals who have made distinguished, influential and on-going, yet forward-looking contributions in the field of scalable computing.
