Abstract:
Les modèles 3D sont des contenus précieux très utilisés dans l'industrie, et donc la cible potentielle de piratages. Le tatouage robuste pour les maillages 3D apporte une réponse au problème du traçage de traître. Dans l'état de l'art du domaine, la couche d'adaptation du contenu en particulier est testée face des attaques standards. Une approche robuste à la pose est alors étudiée. Elle utilise une estimation robuste de l'épaisseur, définie comme la distance un nuage de points construits à partir de mesures du diamètre. Les performances expérimentales montrent qu'elle forme un point de départ

Abstract:
Increasing numbers of alerts produced by network intrusion detection systems (NIDS) have burdened the job of security analysts especially in identifying and responding to them. The tasks of exploring and analysing large quantities of communication network security data are also difficult. This thesis studied the application of visualisation in combination with alerts classifier to make the exploring and understanding of network security alerts data faster and easier. The prototype software, NSAViz, has been developed to visualise and to provide an intuitive presentation of the network security

Abstract:
Monitoring volumes of malicious network data for across multiple sources can potentially be overwhelming. As a result, vital data is at a greater risk of being overlooked and the time span for analyzing it could be too lengthy. One way to address this issue is to employ network security visualization techniques to evaluate security risks and identify malicious activity to help mitigate compromised nodes on a network. The purpose of this thesis is to introduce a visualization framework to help reduce task-completion time, enhance situational awareness, and decrease user error of complex visua

Abstract:
A common method of connecting to the internet is a wireless network. These networks can be monitored to discover the area of their coverage, but commercial receivers don't always provide the most accurate results. A software-defined radio was programmed to sniff wireless signals and tested against a commercial receiver and the results were compared. The results suggest that the software-defined radio performs at least as well as the commercial receiver in distance measurements and significantly better in samples taken per minute. It was determined that the software-defined radio is a viable re

Abstract:
Globally distributed additive manufacturing is a relatively new frontier in the field of product lifecycle management. Designers are independent of additive manufacturing services, often thousands of miles apart. Manufacturing data must be transmitted electronically from designer to manufacturer to realize the benefits of such a system. Unalterable blockchain legers can record transactions between customers, designers, and manufacturers allowing each to trust the other two without needing to be familiar with each other. Although trust can be established, malicious printers or customers sti

Abstract:
This thesis proposes a new method for detecting malicious cyber-physical attacks on additive manufacturing (AM) systems. The method makes use of a physical hash, which links digital data to the manufactured part via a disconnected side-channel measurement system. The disconnection ensures that if the network and/or AM system become compromised, the manufacturer can still rely on the measurement system for attack detection. The physical hash takes the form of a QR code that contains a hash string of the nominal process parameters and toolpath. It is manufactured alongside the original geometry
