Abstract:

Il y a quelques années, un incident de cybersécurité aurait pu facilement être le scénario d'un film hollywoodien : des attaquants ont exploité un point d'entrée inattendu : un thermomètre intelligent dans l'aquarium du hall d'un casino. Cet objet connecté avait accès au réseau du casino, et les pirates ont réussi à le compromettre. Ils ont ensuite utilisé ce point d'entrée initial pour accéder à d'autres parties du réseau et ont finalement exfiltré 20 Go de données sensibles, y compris des informations sur les clients ”gros joueurs”.Cet exploit audacieux met en évidence la vulnérabilité des a

Abstract:

The Open Systems Interconnect Model (OSI) is a conceptual model of networking thatcategorizes network functions into seven layers. It is defined in this model that how layerscommunicate with each other. In this thesis, we address common Layer 2 attacks and theirsolutions. Layer 2 is considered a very weak link in a secure network. If the data is compromisedat Layer 2, it cannot be detected at other layers because each layer works without the knowledgeof other layers. We discuss Layer 2 weakness and vulnerability exploitation tools briefly. It isexplained how an attacker can exploit network by

Abstract:

Confidentiality has always been a concern in secret operation. In this thesis, we consider the situation of legitimate data request and transfer between investigator and database owner who provides intelligence, where the identity of the investigation subject and the records in the database are both confidential. Current practice of secret investigation solely relies on the integrity and carefulness of the involved individuals to resist data leakage, but regulations, policy, agreement, such human means cannot give a promising solution, thus a technical means is needed.

Abstract:

The increased use of computer systems for storing private data or doing critical operations leads to some security issues gathered in the area cybersecurity. This neologism leads people to think about the security of information systems and general-purpose computers. However, with the growth of the Internet of Things, embedded systems are also concerned with these issues. The speed of development of this area often leads to a backwardness in the security features. The thesis investigates the security of embedded systems by focusing on embedded software.

Abstract:

In this thesis, we propose security solutions for pairwise and broadcast communication in mobile ad hoc networks. We use identity-based keys that do not require certificates and that simplify key management. We use pairwise symmetric keys that are computed non-interactively by the nodes, which reduces communication overhead. Our pairwise-key management protocol requires a minimum number of keys, O(N), to be generated by the third party as compared to the conventional pairwise schemes with O(N2). We also propose an efficient identity-based signature scheme for an authenticated broadcast protoc

However, the movement pattern of these mobile wireless nodes is no more random, as in case of mobile networks, rather it is restricted to roads and streets. Vehicular networks have hybrid architecture; it is a combination of both infrastructure and infrastructure-less architectures.

Abstract:

Despite the use of strong encryption schemes, one can still learn information about encrypted data using side channel attacks [2]. Watching what physical memory is being accessed can be such a side channel. One can hide this information by using oblivious simulation - hiding the true access pattern of a program. In this paper we will review the model behind oblivious simulation, attempt to formalize the problem and define a security game. We will review the major solutions pro- posed so far, the square root and hierarchical solutions, as well as propose a new variation on the square root solut

Abstract:

Syftet har varit att på uppdrag av Periallo identifiera vad kunder tycker är viktigast ur ett säkerhetsperspektiv. Detta har skett genom att besvara frågorna vad som är viktigt för konsumenterna ur ett säkerhetsperspek-tiv när de handlar av små e-handelsföretag och vilka säkerhetslösningar samt betallösningar som är relevanta för små e-handelsföretag. Vi har även undersökt om det är värt för ett litet e-handelsföretag att investera i en certifiering. Arbetet har kartlagt betallösningar, säkerhetslösningar och certifieringar med hjälp av en kritisk litteraturstudie och med en enkät, det vill sä

Abstract:

Smart cities utilize IoT cameras in a rushing pace. However, these high technological connected devices are back doors to safe systems. Implementation of high technological solutions without concerning other important aspects as information security and the factor of trust violates not only the quality aspect of the solutions, but also breaches the privacy of individuals. Secure solutions that reserve the trust of individuals with the help of high technological solutions is therefore significant. This study is aimed to investigate and find answer to how IoT camera solutions for smart cities ca

Abstract:

L'Internet des objets (IdO) est une technologie émergente ayant le potentiel d'améliorer notre quotidien de différentes façons. Elle consiste à étendre la connectivité au-delà des appareils standards (tels que les ordinateurs, les tablettes et les smartphones) à tous les objets du quotidien. Ces appareils, également appelés objets intelligents, peuvent alors collecter des données de leur entourage, collaborer pour les traiter puis agir sur leur environnement. Cela augmente leurs fonctionnalités et leur permet d'offrir divers services au profit de la société. Cela dit, de nombreux défis ralenti

Abstract:

L'évolution des techniques d'adaptation et des contenus multimédias adaptables a montré la nécessité de définir des techniques et des pratiques concernant la sécurité des échanges sur les réseaux. Dans la mesure où l'adaptation des documents multimédia nécessite d'autoriser la modification de ces documents entre le serveur et le client, il est important d'étudier les conditions nécessaires pour assurer ces modifications de façon sécurisée. Nous avons donc, dans ce cadre, à présenter un système de communication multimédia qui préserve l'authenticité et l'intégrité des contenus originaux de bout

Abstract:

Avec l'utilisation de notre carte bancaire pour payer un achat sur Internet ou de notre téléphone portable pour nous connecter aux réseaux sociaux, les transactions électroniques font partie de notre quotidien et sont désormais incontournables. Malheureusement, lors de tels échanges, un grand nombre de données personnelles sont transférées et une telle informatisation n'est pas sans conséquence. Les problèmes de sécurisation et de protection de ces données sont bien présents. Dans cette thèse, nous nous concentrons sur la problématique de la protection de la vie privée des utilisateurs dans de
