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).

Log Analysis of Estonian Internet Voting 2013 – 2015

Leave a reply

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.

SEB Estonia Internet bank ID card authentication bypass

Leave a reply

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): 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): 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.

Call for ideas to improve Estonian Internet voting

Leave a reply

Estonian_internet_voting

Electronic Voting Committee invites those interested in Internet voting to attend the day of ideas event, which will take place on Thursday, 18 June, 2015 from 11:00 to 15:00 in the hall of commandant house at Toompea street 1, Tallinn.

I-voting in Estonia has been used already for 8 elections in 10 years. The system has been continuously developed, but since the time of the next regular elections is after little more than two years, it is an opportune time for introducing something larger and more substantial.

Hence the aim for the day of ideas: everyone will have the opportunity to present his ideas or thoughts on how to make i-voting even better, more secure, more transparent, more reliable, etc. – invited are both technical and organizational improvement proposals.

To have a smooth management of the event:
a) register your participation no later than 16 June by sending an e-mail to vvk dot ee.
b) describe in a few sentences the idea and give an estimate on the time needed for the presentation. If you wish, you can show the slides.

Invited are also those who do not have their ideas, but still would like to participate in the debate about the ideas.

Additional information: Tarvi Martens (Head of the Committee)

Analysis and Mitigation of Recent Attacks on Mobile Communication Backend
Abstract: This thesis presents a broad and thorough overview and analysis of the known attacks against mobile network signaling protocols and the possible mitigation strategies. The attacks are presented in a uniform way, in relation to the mobile network protocol standards and signaling scenarios. Moreover, this thesis also presents a new attack that enables a malicious party with access to the signaling network to remove lost or stolen phones from the blacklist that is intended to prevent their use.

Entropy Based Robust Watermarking Algorithm
Abstract: In this work, multiple robust watermarking algorithms are introduced. They embed watermark image into singular values of host image’s blocks with low entropy values. The quantitative and qualitative experimental results are indicating that the proposed algorithms are imperceptible and robust against many signal processing attacks.

Press Release 09.10.2014 Banks will raise the banklink service security

Estonian banking association managing director Katrin Talihärmi said the most important changes concern the comfort and security. “Merchants now have much easier way to set up e-services. In the the past banks used a variety of solutions. Now you can use banklink service to accept payments from customers with similar technical solutions,” explained Talihärm. According to her, the banklink service is made even more secure, since widely implemented digital signatures allow to determine whether the customer uses for authentication ID card, Mobile-ID, PIN-calculator or code card. The new service allows for merchants to use also the IBAN format account numbers.

During the transition period, which lasts until the end of 2015, banks will support both the old and the new banklink protocol format.

The renewed specification is supposed to fix protocol level security flaws discovered previously.
