I like to use cryptobib, because it gives me consistent results and it contains almost everything relevant to me. However, as crypto.bib is over 725000 lines long, parsing it to create the bibliography takes a long time.

In the RFC for TLS 1.3 (RFC8446) especially, the key exchange is defined in terms of (EC)DH key shares being exchanged. This limits us to algorithms which support non-interactive key exchanges, while this is not necessary for the security of TLS 1.

The new TLS 1.3 standard [1] does not yet provide any support for post-quantum algorithms. In this blog post we’ll be talking about how we could negotiate a post-quantum key exchange using a (post-quantum) Key Encapsulation Mechanism (KEM). In the NIST Standardisation effort [2], many KEMs are currently under consideration.

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.

You can set up SSH to prefer Elliptic Curve cryptography over RSA, and use modern key exchange algorithms without exposing yourself to Logjam-style attacks. It’s also good to get rid of SHA1 and MD5.

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.

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.

I’ve had to rename some fields today with MongoEngine. Using the following approach, I was able to raise DeprecationWarnings when old version were used.

Create the following function. It returns a property that will access the new variable name.

Prøst is an authenticated encryption cipher and a contestant in the CAESAR competition for Authenticated Encryption. For my bachelor thesis research project, I’ve implemented Prøst on ARM11. You can find more information about this project on this page.

Today I’ve tried to globally install Powerline. That was a bit of a pain because it has no global config files. Quick and dirty how-to: Add XDG_CONFIG_DIRS=/etc/xdg to /etc/environment if it isn’t already set, Copy the config to /etc/xdg/powerline, Customize config, Load powerline from /etc/bash.
