I’m going to Cuba as my submission to Latincrypt 2017 was accepted! The paper is called Energy-efficient ARM64 Cluster with Cryptanalytic Applications: 80 cores that do not cost you an ARM and a leg. Visit the accompanying page to view the software. I’ll upload the paper once I’m done editing.
Caveat: I found out that the version of Paramiko in Debian Jessie does not support SHA2 hashes or ECC in the key exchange. Paramiko was used in my case by duplicity. If you upgrade to the most recent version from pypi you can use diffie-hellman-exchange-group-sha256.
In July, Peter Schwabe, who supervised my Bachelor’s thesis project, suggested to submit my work to the Student Research Conference. It then turned out that the deadline was the next day, so I had to work hard to convert 28 pages of thesis into a paper of 4 pages.
To my own suprise my paper was accepted for a poster presentation. It was very interesting and challenging to tell the people at the conference (which was at Tilburg University) about my research: I had a very technical story, and a lot of people in the humanities already are scared by the word “encryption”. Nevertheless it was a nice experience and I think I was able to get at least some things through to people.
I’ve updated my Prøst page with the published paper and the poster I presented.
Tegenlicht today had an episode about Bitcoin where they announced they were going to give away €100 in Bitcoin. They were going to put up a Bitcoin wallet private key as a QR-code on the screen.
It seemed to me like a fun project to try and grab that Bitcoin. I coded an app that takes a screenshot every couple seconds and then tries to detect all QR-codes in it. If any of the codes look like a private key, I then used the Blockcypher API to determine the balance and empty the account into my own wallet.
Unfortunately, the NPO stream was probably too slow and I was a couple moments too late. It still was a fun challenge to program though and I learnt a bit about how Bitcoin works.
