Stylization of shadows in ski-panorama maps: A case study on Atelier Novat

Panorama maps can be defined as aerial-view paintings of geologically complex landscapes that are represented in a convenient manner to non-expert viewers. This thesis focuses on a specific variant of panorama maps known as "ski-panorama maps" or "piste-maps" drawn by the french landscape and panorama artist, Pierre Novat. These maps usually...

An Authentication Protocol for Implantable Medical Devices

Proper security mechanism are a crucial part of safe usage of Implantable Medical Devices. Multiple researchers presented various solutions to address this problem, basing them on different underlying principles. Within the scope of this thesis we perform a security analysis of the chosen authentication protocols. What is more, we present a new...

PaDAWaNS: Proactive Domain Abuse Warning and Notification System

The counterfeit market is rapidly expanding into the online realm. Large amounts of fraudulent webshops advertise luxury clothing and fashion accessories, but ship counterfeit products to their customers. Apart from customers, brand owners and domain registries experience a negative impact caused by these fake webshops. Current countermeasures...

Snoring Sound Production and Modelling: Acoustic Tube Modelling

The thesis project is aimed at designing an unobtrusive method to find the obstruction location and severity for patients who are not diagnosed with Obstructive sleep apnea, during their non-sedated sleep using simple recording devices within uncontrolled environment. Similar to speech generation, which is enabled by opening and closing of the...

Honeytrack: Persistent honeypot for the Internet of Things

The number of Internet of Things devices, small low-powered devices with internet connectivity, is undergoing strong growth. As connected devices become the standard, more types of devices are connected to home networks and made accessible from the Internet for convenience. As IoT devices are widely deployed in mass numbers, they can be easily...

Heartwear Security: A lightweight security protocol for Implantable Medical Devices

Modern Implantable Medical Devices (IMDs) are enabled to communicate with an external device trough wireless channels. The non-invasive method allow health-care practitioners to investigate the effectiveness of a treatment delivered by the IMD and tailor it specifically to the patients' needs. The wireless communication capability however, also...

SSH Implementations: State Machine Learning and Analysis

Analyzing large cryptographic protocol implementations can be challenging since their implementations do not perfectly match the standard [6]. The popular, highly configurable remote login method, Secure Shell (SSH) is such an example. In this thesis, we researched the fuzzing methodologies for SSH implementations. Three tools (Backfuzz,...

Packet loss concealment for speech transmissions in real-time wireless applications

Packet communication applications cannot guarantee correct delivery of every packet. Congestions and interferences in the network lead to lost packets. However, real-time applications require timely delivery of data or information and always tolerate packet loss to achieve this aim. When some speech packets are lost, packet loss concealment (PLC...
