Migration From HTTP to HTTPS and a new Domain

Websites with user input should definitely use HTTPS. Since 2014, Google uses HTTPS as a ranking signal. Therefore, even with static websites like the one from my uncle, a migration pays off. We took advantage of the situation to also switch to a more meaningful domain, and with the help of World4You, this was done in two days. After that, I was able to get the full old website running with HTTPS on Now, users are calmed down because Browsers display the site as secure, and nobody can spy on the customers looking for spare parts or repairs. Each legacy site can be migrated!

Bachelor's Thesis: Proof of Concept of Hacking Cryptocurrency Hardware Wallets

Securing cryptocurrency funds require long-term safety. A lot of hardware cryptocurrency wallets were developed, because they offer a way to store the private key offline. This thesis is split up in two parts. The first half analyzes five existing wallets in terms of their software and hardware security design and attestation methods. Then, it presents a classification of exiting attacks for these wallets.

The second half provides a proof of a work of a possible supply chain attack by emulating a hardware wallet on a USB device and tricking the victim into sending his funds to the attackers cryptocurrency account. It proves that wallet software puts too much trust in the hardware and that such a hardware wallet can be emulated. Therefore, the devices are missing important attestations.

Paper: Augmented Reality and its Upcoming Trends in Engineering

Currently, virtual reality and therefore also its related research fields experience a revival. This is mostly due to new hardware developments like the HTC Vive, Microsoft HoloLens and many others. Hence, also augmented reality is now getting a chance to develop further and make interesting breakthroughs. The goal of this paper is, firstly, to give a short overview of state of the art augmented reality technology in general. Then, its new chances and possibilities in the field of engineering are presented, with respect to the classic product lifecycle. In each phase of this lifecycle, possible ways to integrate augmented reality within are covered.
