Agile security for cloud systems? Moti Yung to give a HAIC Talk at Aalto

12. June 2018

Yung is particularly known for coining the term ‘cryptovirology’ and the principles behind it. At his HAIC Talk he will explain how, in ‘the cloud era’, software design and security tool development should be able to keep up with the constantly evolving ecosystem and take note of how cloud systems keep evolving.

yung.pngAdhering to what he calls “agile principles” could also protect cloud systems from attacks and breaches.

‘In an environment where software development, updates and projects are always ongoing, also the cryptography and security designer should be in a state of adaptation to the system's evolution. I will demonstrate this in my talk based on a heavily-used real-world application,’ says Yung, referring to Google’s Advertisement Exchange, which supports the company’s multi-billion-dollar digital advertising.

Designing security tools and cryptographic solutions with the ever-extending scope and inevitable scaling up of the cloud system – such as Google’s Advertisement Exchange, Yung’s focus point in the upcoming talk – would be a way to avoid overly complex changes and loads of development overhead later on.

Yung finds an analogy of the ‘agility principle’ even for keeping every-day users safe from ransomware and all other kinds of attacks.

‘The two things people often think of only as disturbances – systems updates and backups – are in fact most essential! If everyone took care of them frequently, the window of opportunity for attackers would narrow considerably,’ reminds Yung.

Yung’s work on ransomware – the hijacking of systems or data from users or organisations and issuing demands for ransom for releasing the data – also becomes increasingly relevant with the current internet of things trend. The ‘things’ will enable new kinds of security breaches and attacks and prevention tactics need to be planned well in advance.

‘The merging of computing and physical devices will lead to new attacks where ransomware will be replaced by physical consequences.’

‘Any element of the new IoT systems will be a target, and there is not enough investment in their security. Ransomware could cause a man-made disaster if we do not secure the system-level infrastructure,’ believes Yung.

He also cautions that artificial intelligence applied without safety and security in mind will lead to attacks.

Aalto ranked #5 in Europe in empirical operations and supply chain management research

14. May 2018

Aalto University ranked #5 in Europe in the core area of empirically focused research and #11 overall.

Globally, Aalto University was ranked #30 in empirical research in the field in March. More details of the rankings, see SCM Journal List.

‘We are proud of the stream of research that has resulted in a series of publications, for example, in Journal of Operations Management, the number one journal in the field,’ says professor Risto Rajala, Head of the Department of Industrial Engineering and Management.

In comparison to many large universities, Aalto stands out with long-standing and trusted relationships with industrial partners. Thanks to these, much of academic research at Aalto grounds on real-life data on empirical cases and can contribute to grand societal challenges: sustainable growth in industrial operation and the technology-driven transformation of business around the world and across industries.

‘Our particular strength is empirically focused research conducted in close collaboration with industries. Ranking results are not our objective in itself, but they do signal a trajectory that is based on both great talent and hard work in all areas of empirical research: systematic data collection, meticulous analysis, insightful synthesis and visionary crystallization,’ Rajala recounts.

Operations and service management research at Aalto benefits not only from close industrial collaboration but also from transdisciplinary scientific approach and research methods.

“Many departments and groups at Aalto contribute to this field. In addition to the faculty of Industrial Engineering and Management, professors and researchers from the departments of Mathematics and Systems Analysis and Information and Service Economy are integral to our effort,’ notes Rajala.

Education in the field aims to instill collaborative orientation and scientific curiosity into students from the get-go.

‘Our students learn by doing: through real-life cases and research assignments. Our degree programs are rooted in strategic management, entrepreneurial leadership, and digitalisation of operations and services. Top students are often invited to do their master’s thesis research in actual industry projects, and they are capable of conducting analytical research that is both well-grounded and rigorous.’

The SCM Journal List ranking of empirical research is based on output in journals that are primarily empirically focused (including Decision Sciences Journal, Journal of Business Logistics, Journal of Operations Management, and Journal of Supply Chain Management). The ranking of analytical research is based on output in journals that are primarily analytically-focused (including Management Science, Manufacturing and Service Operations Management, Operations Research, and Production and Operations Management).

Mathematical method exposes differences between social and healthcare providers

28. March 2018

The social and healthcare reform is gradually progressing through the Finnish Parliament, but no indices have yet been set for measuring service performance or for comparing the performance of different healthcare units. A new doctoral study from Aalto University’s Department of Mathematics and Systems Analysis presents a method for comparing social and healthcare providers with each other.

Yrjänä Hynninen, who defended his doctoral thesis in March, applied in his work the computational REA method (ratio-based efficiency analysis) for comparing healthcare units, which was developed by his supervisor Professor Ahti Salo and Professor Antti Punkka. According to Hynninen, the method can be used to assess social and healthcare services as a whole and compare different service providers and social and healthcare units.

‘The purpose of the REA method is to describe the activities of a healthcare unit in as multifaceted a manner as possible by comparing an overall assessment composed of different factors. This kind of assessment would not encourage service providers to artificially focus on only one quality index at the expense of other ones’, Hynninen explains.

The important factors to be measured and assessed include the effectiveness and timing of treatments, clinical quality, process efficiency and customer satisfaction.

‘There are often well established indices for different factors, but these are rarely examined together’, Hynninen points out.

Using this method, it is possible to generate comprehensive data about the quality and impact of healthcare unit operations, and the service coordinator can compare the area’s service providers with one another in a coordinated manner. With this public information at their disposal, customers can make considered choices between service providers – thus providing ‘freedom of choice’. At the same time, healthcare units will know from the comparative data what works well and what needs to be improved.

In his doctoral work, Hynninen used REA-method particularly for the comparison of healthcare services in Scotland. The quality criteria being compared included how long patients waited between getting a medical examination and receiving treatment, the quantity of hospital bacteria infections and waiting times in A&E.

For Finland’s social and healthcare reform, the equivalent quality indices and principles for comparing healthcare units are still under development.

‘Once the quality indices have been specified, the REA method can be used to clearly and comprehensively compare the quality and performance of the services of different healthcare units.’

There may be dozens of comparative quality indices for a single social and healthcare unit, so comparing the units with each other and forming an overall picture of the situation becomes complicated and unclear. By making use of the work of the dissertation, units can make decisions based on a comprehensive analysis that deals well with uncertainty.

‘When the best operating practices can be identified, they can then be made use of elsewhere as well. In this way, limited resources can be allocated wisely and greater health benefits can be achieved’, Hynninen emphasises.

Individual commentaries are drawn from the Dean's introductions and statements made of each awardee's work.

Lari Koponen (NBE)

Implementing advanced transcranial magnetic stimulation technology

'Lari Koponen developed methodology for transcranial magnetic stimulation.  He solved the previously unsolved problem of minimum-energy TMS coil design. His multi-coil techniques allow electronic targeting of the magnetic stimuli. He also developed a way to measure microsecond-scale neuronal membrane kinetics noninvasively from humans. Lari’s results will soon lead to closed-loop stimulation: algorithms will decide in fractions of a second what spot of the brain should be stimulated next, depending on feedback signals. This is expected to lead to new possibilities in neuroscience and a breakthrough in clinical diagnostics and therapy.

Professor Stefan Goetz from the best American TMS-technology laboratory, at Duke University, wrote as opponent’s final statement: "Mr. Koponen's work is highly innovative and will permanently shape the field of noninvasive brain stimulation through the technologies he conceived and created."

The pre-examiners were similarly impressed. Prof. Jens Haueisen: "I can only congratulate the candidate … for this enormous amount of accomplished work, which I find of exceptional quality.”'


Orestis Kostakis (CS)

Advances in Analysing Temporal Data

'The dissertation of Dr. Orestis Kostakis is on the topic of analyzing temporal data. It goes beyond traditional time-series data and considers more complex data types, which are abound in the modern Big Data era.

The impact of the dissertation is supported by applications in areas such as American sign language processing, sports analytics, and data security. In particular, the algorithms in the dissertation have been tested in a deployed system running in the premises of a world-leading Data Security corporation.

The results presented in the dissertation have both solid foundations and practical applicability. The dissertation is not only a step ahead in the analysis of temporal data, but also, and perhaps more importantly, it opens new directions for future research.'


Ville Liljeström (PHYS)

Electrostatic Self-Assembly - From Proteins, Viruses, and Nanoparticles to Functional Materials

'In his PhD studies, Ville focused on the self-assembly of biological and synthetic nanoparticles. His research has open new ways to pack viruses into crystalline form, which can be utilized for example in vaccine development or to develop optical polarizers. (...) Ville has shown to be highly capable of crossing the disciplinary boundaries between physics, chemistry, biochemistry and materials science. He has a systematic and through approach to science, which has allowed him to obtain relevant results and analyse them in coherent manner. The results of his studies have been published in the top ranked international journals, including first author publications for example in Nature Communications and ACS Nano.'



Yu Liu (DIEM)

Antecedents and Outcomes of Partnering Abroad with Local Firms: Evidence from Cross-border Venture Capital

'The doctoral dissertation of Yu Liu focuses on when firms can benefit from partnering with local firms when entering foreign markets. The dissertation contributes to the research on international entrepreneurship and cross-border venture capital. The new knowledge created in the doctoral dissertation has practical value for entrepreneurial firms and venture capitalists developing partnering strategies when entering foreign markets and for policy makers developing the functioning of international risk capital markets. Findings of the dissertation have so far been published in Academy of Management Journal, the leading journal focused on empirical management research. Following the graduation at Aalto University, Dr. Yu Liu was appointed as Assistant Professor of Strategic Entrepreneurship in the Department of Strategic Management and Entrepreneurship, Rotterdam School of Management, Erasmus University, one of the leading European universities in entrepreneurship and strategy research.'


Ilya Nikolaevskiy (CS)

Scalability and Resiliency of Static Routing

'The presented dissertation concentrates on the investigation of Scalability and Resiliency of Static Routing and correspondent implications of its optimization. The dissertation presents a deep assessment and investigation of the class of static routing algorithms from two the most crucial performance characteristics namely scalability and resiliency. Being simple, yet efficient, static routing algorithms are not yet fully investigated and the limits of their applicability are not fully understood. The topic of the thesis is up-to-date and under investigation by the worldwide research community. The presented achievements are mostly of theoretical flavor with large practical potentials and targeted over development of algorithms and models. Within some feasible time the developments presented in the dissertation, will appear in real networks.'



Natalie Segercrantz (PHYS)

Optoelectronic properties of III-V compounds and alloys

'Dr. Natalie Segercrantz made her doctoral thesis, consisting of 6 peer-reviewed articles (4 in Applied Physics Letters, 1 in Physical Review B and 1 in Journal of Applied Physics), in less than 4 years. The quality and innovativeness of her work are on the highest level, as pointed out by the pre-examiners and the opponent who all represent different fields: experimental semiconductor physics, electronic device fabrication and computational materials theory. Overall, Dr. Segercrantz’s work during her thesis resulted in more than 12 peer-reviewed papers, and they are already highly cited taking into account the typical citation numbers and immediacy indices.

Two very important aspects in Dr. Segercrantz’s work should be pointed out. First, she performed state-of-the-art experiments AND theoretical calculations by herself in her thesis, in addition to developing experimental approaches. Second, she organized (again by herself, including funding) a 9-month research visit to Lawrence Berkeley National Laboratory (USA). This visit resulted in 4 papers (2 with her as first author are in her thesis) that she wrote together with the scientists in the US, without her supervisor demonstrating the high level of independence that she has. After graduating from Aalto University she has started her post-doctoral career at the Walther Meissner Institute, Munich, Germany.'


Konstantin Tiurev (PHYS)
Quantum Knots and Monopoles

'The thesis of Dr. Konstantin Tiurev reports observations of quantum-mechanical monopoles and quantum knots through publications in high-impact journals such as Science and Nature Physics. Quantum knots and monopoles are fundamental topological structures which have not been previously observed in any quantum field. However, they are theoretically predicted to exist in various different contexts such as in the magnetic monopole particle. Thus the results of Dr. Tiurev's thesis will have an exceptionally long-lasting fundamental impact on science.'


Emanuele Ventura (MS)

Geometry of Real Tensors and Phylogenetics

'Ventura's thesis was on how to apply the most pure part of mathematics, algebraic geometry. He proved several difficult results improving on some questions stated centuries ago using the most contemporary tools. Together with Michalek he proved a conjecture by Sturmfels at UC Berkeley, which was motivated by putting an heuristic by the Pachter computational genomics group at Caltech on a firm basis.'

The technology sector is more versatile than girls in middle school had thought

8. March 2018

‘Education in the technology sector opens doors to various career paths. The work involves international cooperation, so good skills in English and communication will take you far’, summarised women working in the technology sector for a room full of girls in junior high school in an event held 8 March 2018.

‘Studying technology opens huge opportunities in working life. In addition, the studies in this field are also fun’, said Carmela Kantor-Aaltonen from the Chemical Industry Federation of Finland.

Professor Hele Savin, last year’s recipient of the innovation award for women, told about her own career path as a researcher. ‘In upper secondary school, I didn’t know yet what my field would be. On the first courses at the Helsinki University of Technology, I quickly realised that I was studying the right field for me. A summer job in a research group sparked my interest in doing research. I found my field of research in the University of Berkeley where I was introduced to solar energy and its research. I understood that it is a field of the future’, explained Hele Savin.

‘Research is done together in an international group. In addition to doing research together, an important part of being a researcher is telling others about your results as much as possible.’

Professor Savin encouraged the students to go into the technology sector, but the most important thing is to choose a field based on what you are interested in: ‘No matter the field, you should choose it based on what you like.’


The students visited the Electrical Engineering Workshop where Kimmo Silvonen introduced coursework done by students: automatically operating curtains.

For Riitta Silvennoinen, her studies in chemical engineering have provided a basis for working in research as well as industry. Currently, she is employed in Sitra, working with tasks related to circular economy.

‘Studying natural sciences pays off because I can apply for tasks where I can truly have an impact on saving the world and therefore saving people.’

Student of Technology Saijariitta Kuokkanen agreed with the other speakers; the technology sector provides opportunities to work in a wide variety of tasks.

"Going on exchange during studies is becoming more popular still. But even if you didn't study abroad, there are thankfully many opportunities in working life to get international experience.

Marjo Äijälä from Borealis Polymers Oy encouraged the students to keep windows open in all directions.

‘Don’t close off any opportunities. In the technology sector, you don't graduate for any particular task; instead, you can do a variety of things. You should go without prejudice into this field that's talked about as a men’s field. What matters in working life is skill, not gender.’

Kaisa Junka from ABB said that the work in the technology sector is creative problem solving.

‘I urge you to apply for mechanical and electrical engineering because there are interesting tasks available in these fields.’

Aino Achrén and Ada-Lotta Virtanen, 9th grade students from Salo, thought the day was interesting.

‘The technology sector is different than we had imagined. It's more varied than I had thought.’

‘Today was an eye-opening experience. I had thought that you only sit at the computer if you're working in technology, but I learned that it involves a lot of working with other people and that going abroad is also possible.’

The event was finished with workshops on solar panels and Arduinos. In addition, the students got to make a fitness application for their own phones. The students were also introduced to the Aalto satellites and a virtual journey to space.

During the day, 90 middle school girls from the Armfelt school in Salo, Härkävehmaa school in Hyvinkää and Olari school in Espoo visited Aalto University.

Professor emerita Kaisa Nyberg receives Finnish Cultural Foundation award

27. February 2018

Professor Emerita Kaisa Nyberg at Aalto University has studied mathematical methods of secure communications. Nyberg served as Professor of Cryptology from 2005 until her retirement in 2016. She is very moved by the Finnish Cultural Foundation's award.

'Prizes have been awarded by the Finnish Cultural Foundation since the early 1940s, initially to several builders of Finnish society in the fields of science and art. I feel myself very small in that company. Past recipients of the prize that I could mention are Alvar Aalto in 1949 and Teuvo Kohonen, Professor Emeritus and Member of the Academy of Finland, who is world-known for his research into neural networks and won the prize in 1994' says Kaisa Nyberg.

Kaisa Nyberg succeeded in developing and establishing teaching and research into cryptology in Finland. She has also sought to use her own example to encourage an increasing number of young women to find their own field in the mathematical and technical sciences.

Starting in 1987, before her professorship at Aalto University, Kaisa Nyberg had a doctorate in mathematics and served in the Finnish Defence Forces. From the Defence Forces Nyberg went to the Nokia Research Centre in order to gain some industrial experience. This happened in 1998. At Nokia Nyberg did research on encryption methods for mobile phones as part of an international group of experts. The encryption techniques - the standardized solutions developed at that time - are currently in use in billions of mobile devices around the world.

Nyberg has also developed a pairing method for Bluetooth devices in cooperation with other experts from Nokia and Microsoft. Nyberg has also served as an expert in data security in the design of various critical systems, such as preparations for on-line voting for citizens.

At its annual celebration on 27 February the Finnish Cultural Foundation awarded three prizes worth 30,000 euros each for outstanding cultural achievements. The prizes were won by professor emerita Kaisa Nyberg, designer and textile artist Markku Piri and film director and screenwriter Selma Vilhunen.
