Vasiliki Liagkou holds a B.Sc. in Computer Engineering & Informatics, a M.Sc. in Foundations of Computer Science and a PhD in Cryptography and Cryptanalysis of Secure and Trust communication protocols from the Department of Computer Engineering and Informatics of Patras University. She is also, an Adjunct Professor at the Technical Institute of Mesologgi. She is a research fellow in Research and Academic Computer Technology Institute and participated in several national and EU funded projects, such as the IST Projects ABC4Trust, FRONTS, FLAGS and AEOLUS, the national HYPERGEN project (development of the EXTRA5 and SUPER3 electronic lotteries). She has also worked as an Adjunct Professor at the Department of Management of Cultural Environment and New Technologies of University of Western Greece. She has published several works in international conferences and journals and has served as an external reviewer for international conferences. Her main research interests include system cryptanalysis, system security, public key cryptography, trust management, pseudorandom generators, algorithm engineering, number theory, wireless sensor networks.

I worked as an M.Sc Enginnered:
1. in the European research project FLAGS (FP5 IST / FET STREP Project IST-33116), the research objectives was to develop algorithms in dynamic environments, such as autonomous entities, dynamic environments of many agents (multi-agent) and ad -hoc mobile networks.
2. in the national project "Monitoring, maintenance, upgrading and integration of Lotteries systems HYPERGENII."
3.in the European research project AEOLUS (FP6 IST / FET Integrated Project IST-015964). The purpose of this research was to develop an Overlay Computer that supports secure access to its contents via Internet and wireless networks.

The goal of ABC4Trust is to address the federation and interchangeability of technologies that support trustworthy yet privacy-preserving Attribute-based Credentials (ABC). So far, credentials such as digitally signed pieces of personal information or other information used to authenticate or identify a user were not designed to respect the users privacy. They inevitably reveal the identity of the holder even though the application at hand often needs much less information, for instance only the confirmation that the holder is a teenager or is eligible for social benefits. In contrast to that, Attribute-based Credentials allow a holder to reveal just the minimal information required by the application, without giving away full identity information. These credentials thus facilitate the implementation of a trustworthy and at the same time privacy-protecting digital society.
The aim of this project is to establish the foundations of adaptive networked societies of small or tiny heterogeneous artifacts. We indent to develop an understanding of such societies that will enable us to establish their fundamental properties and laws, as well as, their inherent trade-offs. We will approach our goal by working on a usable quantitative theory of networked adaptation based on rigorous and measurable gains. We also indent to apply our models, methods, and results to the scrutiny of large scale simulations and experiments, from which we expect to obtain valuable feedback. The foundational results and the feedback from simulations and experiments will form a unifying framework for adaptive nets of artifacts that hopefully will enable us to come up with a coherent working set of design rules for such systems. In a nutshell, we will work towards a science of adaptive organization of pervasive networks of small or tiny artifacts.
The overall objective of the project is to improve the research potential and capability of selected WBC research centres and to develop them into wireless sensor networking centres of excellence capable of driving the research agenda and serving as a seed for development of other similar centres in the region. The main course of action will be to leverage already achieved results and continue building established relationship between the WBC and the EU institutions and researchers through collaboration on specific use cases with high significance for socio-economic needs of the WB countries. Two use cases, one for each WBC centre, have been selected as particularly interesting and beneficial for the WBC region: personal health monitoring systems (including systems for support of independent living) and emergency/disaster recovery applications. These use cases are the common theme of all project activities that are organized in such a way to address and explore the most important research issues relevant to the selected use cases. This will be achieved on one side through an active and organized exchange of researchers and on the other side through exchange of scientific know-how and RTD results at a series of workshops and seminars. The said activities will reinforce the research potential of the WBC and the EU’s convergence partners, providing a sustainable research platform for future needs of the region and the wider EU community
The recent explosive growth of the Internet gives rise to the possibility of a global computer of grand-scale consisting of Internet-connected computing entities (possibly mobile, with varying computational capabilities, connected among them with different communication media), globally available and able to provide to its users a rich menu of high-level integrated services that make use of its aggregated computational power, storage space, and information resources. Achieving this efficiently and transparently is a major challenge that can be overcome by introducing an intermediate layer, the overlay computer. The goal of AEOLUS is to investigate the principles and develop the algorithmic methods for building such an overlay computer that enables this efficient and transparent access to the resources of an Internet-based global computer.
The aim of the project is to provide a unifying scientific framework and a coherent set of design rules, for global systems resulting from the integration of autonomous interacting entities, dynamic multi-agent environments and ad-hoc mobile networks. The focus will be on the issues of co-operation and antagonism, stability and fault-tolerance, as well as communication and motion in such global systems.
The CORAS' main objectives are: a) to develop a practical framework for a precise, unambiguous and efficient risk analysis, by exploiting the synthesis of risk analysis methods with semiformal specification methods (in particular, methods for object oriented modelling) and computerized tools, in order to improve the risk analysis of security critical systems, b) to assess the applicability, usability and efficiency of the framework by extensive experimentation in the fields of e-commerce and telemedicine, c) to investigate the method's commercial viability and pursue its exploitation within relevant market segments, while playing an influential role in standardization organizations.
The goal of this project is the development of an innovative software for the protection of executable and data files of a D.V.D.-R.O.M., and allow the access of the content from the Internet. The project consists of three components. The first component deals with the development of the software that forbids the illegal copy of the content of a D.V.D.. The second component deals with the development of a software that supports safe transactions through the internet by using mechanisms of access control and advanced cryptographic techniques. The third component of the project, deals with the development of software that authenticates the origin of data file which are under copyright (audio, video files and movies). These three components will integrate into a software package which can be used in a wide range of DVDROM applications.
