Carbonara, ett bildkompressionsformat

Grundnivå (16hp)
kl 08:30, John Von Neumann (På svenska)
High-speed laser triangulation 3D cameras, such as the Ranger3 from SICK, transmit
image data to a PC for processing. The camera’s operational speed is constrained by the
capabilities of the transmission link. By compressing the data, the bandwidth requirements
of the camera is reduced. This thesis presents the development of a lossless image
compression format developed for this purpose.

The proposed image compression format features a single-pass encoder that utilizes
run-length and delta encoding. It is designed to be suitable for implementation on
field-programmable gate arrays (FPGAs) within high-speed laser-scanning cameras.
Furthermore, the format offers configurability through parameters, enabling optimization for
diverse types of image data to achieve more efficient compression.

The compression ratio of the image compression format was evaluated using a range of
typical images captured by a Ranger3 camera. The compression ratio was measured across
different configurations of the format and subsequently compared with that of PNG. The
compression ratio achieved by the proposed format is on par with that of the PNG format,
despite having a much simpler encoding process

Asserting password crackers ability to target Swedish passwords

In today’s digital world, passwords are the keys that unlock our online lives, keeping our social media, financial accounts, and streaming services secure. Unfortunately, this makes password information a prime target for hackers, who can gain access to our entire digital existence. One significant vulnerability is that an individual’s language and cultural background often influence password creation.

This master’s thesis explores the realm of password security by examining the ability of popular password cracking and mangling tools to target passwords created by Swedish speakers. The study compares attacks on passwords created by Swedish speakers to those created by international users. The tools under scrutiny include Probabilistic Context Free Grammar (PCFG), Ordered Markov Enumerator (OMEN), Odinn, and Hashcat. The study examines a method for measuring the quality of the tools’ password guesses.

The findings revealed a noteworthy trend: all the tools demonstrated better performance when attacking passwords created by Swedish speakers compared to their international counterparts. PCFG, in particular, was nearly twice as effective against Swedish passwords after just 10,000 guesses, while OMEN outperformed significantly against Swedish targets after 1-5 million guesses.

The quality measurements, gauged by the percentage of cracked passwords after specific guess increments of 10,000, 1-5 million, and 1 billion were used to evaluate the effectiveness of the tools. This research highlights the nuanced dynamics of password security, emphasizing the impact of linguistic and cultural factors on the vulnerability of passwords.
