Using the Estonian Electronic Identity Card for Authentication to a Machine

Abstract: The electronic chip of the Estonian ID card is widely used in Estonia to identify the cardholder to a machine. For example, the electronic ID card can be used to collect rewards in customer loyalty programs, authenticate to public printers and self-checkout machines in libraries, and even unlock doors and gain access to restricted areas.
This paper studies the security aspects of using the Estonian ID card for this purpose. The paper shows that the way the ID card is currently being used provides little to no assurance to the terminal about the identity of the cardholder. To demonstrate this, an ID card emulator is built, which emulates the electronic chip of the Estonian ID card as much as possible and is able to successfully impersonate the real ID card to the terminals deployed in practice. The exact mechanisms used by the terminals to authenticate the ID card are studied and possible security improvements for the Estonian ID card are discussed.

The TLDR; of the paper is that when the ID card is used to authenticate to a machine (unless PIN1/PIN2 is involved), the ID card does not provide additional authentication factor. This is not a surprise to anyone who is familiar with the technology, but some still believe that ID card provides some security over the magnetic-stripe card.

The paper describes proof-of-concept implementation of non-cryptographic “ID card emulator” and demonstrates transplantation of the fake chip to a real ID card.

Homomorphic Tallying for the Estonian Internet Voting System

Estonian_internet_voting

Abstract. In this paper we study the feasibility of using homomorphic tallying in the Estonian Internet voting system. The paper analyzes the security benefits provided by homomorphic tallying, the costs introduced and the required changes to the voting system. We find that homomorphic tallying has several security benefits, such as improved ballot secrecy, public verifiability of the vote tallying server and the possibility for observers to recalculate the tally without compromising ballot secrecy. The use of modern elliptic curve cryptography allows homomorphic tallying to be implemented without a significant loss of performance.
[..]
The homomorphic tallying scheme described above is not new. The scheme was introduced in 1997 by Cramer et al. [6] and has been used in the Helios open-audit voting system [1] for years. The contribution of this paper is an analysis of the deployment of homomorphic tallying in the context of Estonian Internet voting, where the performance of the protocol is improved by the use of elliptic curve cryptography.

In the new tender specification published by National Electoral Committee (NEC) we can read that there is a plan to use some kind of mix-net-based technology to provide counted-as-cast verifiability for the local government elections in October 2017. While mix-nets cryptographically are more complicated than homomorphic tallying, the mix-nets are more universal and thus can be used also in elections abroad, where the ballot style is not as simple as in Estonia (e.g., elections where the voter can vote for more than one candidate).

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.

Log Analysis of Estonian Internet Voting 2013 – 2015

Log server

Conclusions
In this work we developed a systematic data analysis method that can be used to assess the state of an ongoing i-voting and to perform post-election analysis.
The log monitoring solution developed has been a useful tool for detecting software bugs and logging deficiencies, which might not have been otherwise detected.

Although the three elections analyzed in this study were different types of elections, we can see that most of the measured values are similar. Furthermore, taking into account all the observations, we can conclude that in KOV2013, EP2014 and RK2015, no large-scale attack against i-voters was carried out.

E-enabled elections in Estonia: Forum on research and development in 2015

Estonian_internet_voting

During the first half day, Estonian researchers will present the results of a 3-year scientific project that studied the Estonian flavour of verifiable Internet voting from both technical and social aspects. The second half of the first day will be devoted to the presentation of the development ideas of the Estonian solution. The second day holds additional interventions on the topic of remote online voting and offers brainstorming activity where feedback to the ideas of the first day will be gathered interactively.

SEB Estonia Internet bank ID card authentication bypass

SEB_Estonia_authentication_bypass

The flaw in SEB Estonia Internet bank allows to login just by knowing the victim’s username. The consequences of the flaw go beyond the read-only access to victim’s transaction history. The victim can be impersonated in any website that supports authentication through SEB (eesti.ee, mnt.ee, tele2.ee, etc.). The flaw can be abused to buy goods from online merchants (as shown in the video) since SEB does not require signature authorization for “banklink” transactions.

Timeline:
2015.05.11. 13:00 – reported to CERT-EE
2015.05.14. 12:00 – fixed by SEB Estonia

The time that was required for SEB to fix such a critical flaw surprises a bit.

SEB’s response:

SEB spokesman commented that “referred security issue existed in so-called laboratory conditions meaning that it needed several conditions to coincide and a specific knowledge”.

“Security issue got fixed and we also checked that the flaw was not maliciously exploited” said SEB’s spokesman and added that the problem got fixed faster than in an hour, after all the needed information was received.

Anto_Veldre_RIA_SEB_turvaauk

Anto Veldre (RIA): It is better that ethical people with academic degree are looking for security holes than cyber criminals doing it. People should understand that new technology is complicated, systems at home and servers need to have updates everyday there is no such a thing like secure system (security) but there are people and control methods, if there is a problem it will be handled and afterwards logs are checked if something really happened.

Silver_Vohu_SEB_turvaauk

Silver Vohu (SEB): It took less than an hour to make a fix. But reproducing the situation took most of the days and asking additional questions from CERT-EE was needed. In normal situation it was impossible to reproduce the problem.
