Role Based Access Control as SecureUML Model in Web Applications Development with Spring Security
Abstract: In order to support and simplify the model-driven approach for a web application development with Spring platform, realization of a concept plugin for Eclipse IDE is proposed. This plugin supports the recognition of Spring Security notations with capability to visualize the RBAC model on top of them.

Secure and Efficient Mix-Nets
Abstract: This thesis studies a zero-knowledge shuffle argument proposed by J. Furukawa in 2005. Firstly, we provide a more detailed and easily readable description of the shuffle and shuffle-decryption zero-knowledge protocols than in the original paper. Secondly, we provide two new characterizations of a permutation matrix and two simple modifications of the shuffle protocol that reduce the computational complexity.

A Comprehensive Protocol Suite for Secure Two-Party Computation
Abstract: In some scenarios, a two-party model is a better fit when no natural third party is involved in the application. In this work, we design and implement a full protocol suite for two-party computations on Sharemind, providing an alternative and viable solution in such cases.

An improved type system for a privacy-aware programming language and its practical applications
Abstract: he goal of this thesis is to make it easier to add protection domain kinds to the SecreC language by allowing the programmer to define the protection domain kind data types, arithmetic operations and type conversions in the SecreC language without changing the compiler.

Energy Harvesting in Cooperative Communications
Abstract: Energy harvesting (EH) is a crucial technology for a variety of wireless systems that have limited access to a reliable electricity supply or recharging sources. In this thesis, the design of a multiple access relay system (MARS) using EH is considered.

Security of Eduroam Passwords
Abstract: The University of Tartu has decided that the university’s eduroam accounts will share the same user credentials as the rest of the university’s services. This could potentially be abused by exploiting weaknesses in wireless security in order to gain access to a user’s university account. The aim of this research was to uncover any such weaknesses.

Cache-Timing Techniques: Exploiting the DSA Algorithm
Abstract: This work explains some of the cache-timing techniques commonly used to exploit vulnerable software. Using a particular combination of techniques and exploiting a vulnerability found in the implementation of the DSA signature scheme in the OpenSSL shared library, a cache-timing attack is performed against the DSA’s sliding window exponentiation algorithm.

RIA Cyber Security Report 2015


Some insights:

2015 proved that the continuity of vital services can be affected, or even crippled, by simple ransomware campaigns that weren’t even intended to disrupt those services.

Around-the-clock manned monitoring of Estonian cyberspace has taken place since the summer of 2015. We also adopted new and improved monitoring technologies.As a result of the around-the-clock monitoring, we have prevented, discovered, and reacted to signifcantly more security incidents than in past years.

In 2015, the lessons learned from the CyberHEDGEHOG 2015 exercise, the amendment of the Emergency Act, and the adoption of the European Union Network and Information Security Directive (NIS) confrmed the need for a clear cyber security law that takes into account modern conditions.

In 2015 we became convinced about the necessity of thoroughly analysing both the legal questions associated with using cloud technologies and the risks connected to the integrity and confidentiality of data being processed in the cloud as well as the need to develop sufficient security measures to minimise those risks.

While European Union structural funds have been a welcome source of support for Estonian cyber security development, and indeed for the whole country’s IT development, it is clear that this situation is not sustainable for the country in the long term.


Russian special forces operated fake GSM base station in Pärnu


In April 2015 NATO brought their special forces to Estonia for a secret NATO exercise. In the days that followed Russia unleashed a series of aggressive counter measures to monitor their exercises.

Estonian signals intelligence quickly discovered an IMSI-catcher – a false cell phone tower in the local cellular network. NATO believes that the Russians attempted to identify the key NATO personnel.

Classified NATO report: “The ghost tower came online briefly twice during the day. It overtook all local towers and hijacked all the local recipients before it dropped offline.”
