Ahto Truu presentation “Next-gen Key Infrastructure with Smart-ID”

XII. Tartu Software Development Guild Meeting, Friday, January 13, 2016, 18.00 – 20.00, Turu 2 (Tasku), 5th Floor, SaleMove Office

Presenter: Ahto Truu (Software Architect at Guardtime)
Title: Next-gen Key Infrastructure with Smart-ID
Abstract: With more and more people using smartphones and tablets as their computing devices of choice, and with the upcoming migration away from physical SIM cards, a question arises: what will replace the ID-cards and mobile-ID SIM cards as the carriers of the private keys for Estonian national digital signature infrastructure? In this talk we will look at the Smart-ID solution recently jointly proposed by Sertifitseerimiskeskus and Cybernetica. There will be quite a bit of math in the talk, but we will start with a crash course of the basics of the current systems for those who either missed it in school or have since forgotten the details.

About Ahto
During his three decades in ICT, Ahto has worked in hardware installations and user support, as a software developer and architect, and as a systems analyst. Currently he is busy helping Guardtime’s customers preserve the integrity of their important data. Outside his day job he coaches Estonia’s team to the high school students’ programming competitions. He has also been writing programming columns for the popular science magazines A&A and Horisont.

Seems that Ahto plans to describe the underlying details of key generation in the Smart-ID solution.

Call for ideas to improve Estonian Internet voting

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)

Presentations:

Sven Heiberg “What is possible for 2017”
Ivo Kubjas “Mixnets – why, what and how?
Arnis Paršovs “Homomorphic Tallying for Estonian Internet Voting”
Tanel Tammet “About e-election problems”
Ahto Truu “Data integrity detection KSI service”
