SaS Seminars

Software and Systems Research Seminar Series

The SaS Seminars are a permanent series of open seminars of the Division of Software and Systems (SaS) at the Department of Computer and Information Science (IDA), Linköping University. The objective of the seminars is to present outstanding research and ideas/problems relevant for SaS present and future activities. In particular, seminars cover the SaS research areas software engineering, programming environments, system software, embedded SW/HW systems, computer systems engineering, realtime systems, parallel and distributed computing, and theoretical computer science. - Two kinds of seminars are planned:

  • talks by invited speakers not affiliated with SaS,

  • internal seminars presenting lab research to whole SaS.

The speakers are expected to give a broad perspective of the presented research, adressing the audience with a general computer science background but possibly with no specific knowledge in the domain of the presented research. The normal length of a presentation is 60 minutes, including discussion.

Enabling Advanced Wireless Communication Network

Dr. Dr. Aloizio P. Silva University of Bristol, United Kingdom.

Tuesday, November 13th, 2018 kl 13:15-14:00 room John von Neumann.

In future networks intelligence will be integrated into infrastructure. Cars will drive themselves, cities will be safer for citizens, houses will be self-cleaning, agriculture will work sustainably, electrical grids will respond automatically to fluxes in energy demands and Interplanetary Internet (IPN) will interconnect planets. The reality is that we will live in a smarter, more connected world.

The evergrowing exploration and demand for wireless data has pushed researchers to search for new technologies in order to significantly expand network capacity and capability. Industry and academia experts universally agree that, even with current and planned infrastructure rollouts, service demand will continue to outpace capacity and shifting the debate from ?where? to ?when? this will occur. Service providers plan to furiously upgrade their networks to enable advanced technologies and beyond, adopting new innovations including network softwarization, along the 3GPP and IETF roadmap. However, it is clear that the current technology trajectory still produces a capacity slope more flat than the demand line.

Embracing this challenge, researchers around the world have begun their journey to investigate new network technologies that will be part of the advanced wireless communication networks. Researchers are not only addressing capacity in their innovations, they also aim to improve coverage and reliability at the cell edges, improve energy efficiency for providing service, and decrease latency - all of which will improve the overall responsiveness of the network. To this end, researchers are focusing on potential technologies (Artificial Intelligence and Network Softwarization) to build advanced testing networks to make 5G and beyond a reality. It is an ambitious undertaking, and getting there will require infrastructure and user equipment that can operate cross-domain within a much broader bandwidth at incomparably higher speeds. It is going to be wonderful, and it is going to change the way the network behaves. This debate is divided into two strands. Firstly, it highlights the industry and researchers collaboration as a single platform to discuss this challenge of tomorrow. It also presents one of the most prominent 5G-test networks deployed at Bristol City Center in the UK and briefly describes two European H2020 projects 5GinFIRE and FLAME platforms. Second, it goes through the Interplanetary Network domain and discusses an intelligent approach for mitigating congestion in dynamic and intermittent networks.

Browser Extensions: Development practices, unwanted behaviors and how to anticipate them

Dr. Aruna Prem Bianzino researcher at Telefonica Digital Espana (Eleven Paths).

Monday, September 17th, 2018, kl 10:15 room Alan Turing.

Browser Extensions: Development practices, unwanted behaviors and how to anticipate them Browsers represent the main tool to access web content. Browser extensions increase the functionalities of browsers, offering any kind of non-standard solutions and applications to the end user, resulting in a really popular practice, accessing many resources, and bringing with them security risks. We analyze the ecosystem of the browser extensions, and develop a solution to automatically highlight eventual unwanted behavior, which is eluding the current pre-market analysis. This solution allows also to increase the transparency and user awareness and control over the used extensions and their resource usage and access policy.

Towards next-generation collaborative network defense

Dr. Emmanouil Vasilomanolakis, Technical university of Darmstadt, Germany.

Tuesday, June 19th, 2018, kl 13:15 room Alan Turing.

Cyber-attacks have nowadays become more frightening than ever before. The growing dependency of our society on networked systems aggravates these threats; from interconnected corporate networks and industrial control systems to smart households, the attack surface for the adversaries is increasing. I argue that network security requires, besides traditional methods, more out of the box and (pro)active research. In this talk, I will discuss the three main pillars of my current and future research, namely: i) offensive security, ii) attacker deception, and iii) collaborative intrusion detection. In particular, the first part of the talk will focus on offensive security (e.g., taking the perspective of an adversary to anticipate new attacks) and attacker deception (e.g., honeypots) and will examine the motivation, the challenges and possible next steps for this line of research. The second part of the talk will be emphasizing on collaborative intrusion detection and will combine a discussion of research challenges along with lessons learned from a number of projects that I have been involved to date.

Bio of speaker:
Dr. Emmanouil Vasilomanolakis is a senior researcher at Technische Universität Darmstadt. His research interests include collaborative intrusion detection, honeypots and botnet monitoring. Emmanouil received a PhD, for his thesis "On Collaborative Intrusion Detection", from the Technische Universität Darmstadt (Germany) in 2016 and a diploma (Dipl.-Inform.) and MSc (IT Security) from the University of the Aegean (Greece) in 2008 and 2011 respectively.

Fog Computing with Reference Attribute Grammars

Prof. Dr. Uwe Aßmann Technical University of Dresden, Germany.

Friday, April 20th, 2018, kl 14:15 room Alan Turing.

Fog Computing is a new reference architecture for sensor networks at the edge of the cloud. Its basic idea is to process data locally, in complex sensor nodes, gateways and routers, before moving them into the cloud. Thereby, it protects privacy by default and delivers speed (low latency, high bandwidth). Its business perspectives for European companies are tremendous, because starting from the sensor markets, they can penetrate the future cloud computing markets. Fog Computing has a very interesting application area, Robotic Co-Working. The talk reports about a case study in fog computing: the Chair of Software Engineering has combined several co-working robots, such as the KUKA LBR iiwa or the UR-10, with a sensor-equipped jacket and glove. A fog collects and aggregates all sensor data via a gateway, a laptop, and a robot server. Starting from this example, we show how to program a fog, with a world statechart and an adaptive software platform based on contexts and roles. Fog computing will enable life with wearables and machines in smarter rooms. Fogs mean smartness. Fogs can be programmed with event-based RAGs if events are admitted as input to an attributed tree. We give some examples of the models that are required for modeling fogs.
