Abstract:
Distributed protocols allow a cryptographic scheme to distribute its operation among a group of participants (servers). This new concept of cryptosystems was introduced by Desmedt [56]. We consider two different flavours of distributed protocols. One of them considers a distributed model with n parties where all of these parties are honest. The other allows up to t − 1 parties to be faulty. Such cryptosystems are called threshold cryptosystems. The distribution of cryptographic process is based on secret sharing techniques and is usually applicable to public-key cryptosystems. In this thesis w

Cette thèse aborde différents aspects de la cryptologie, subsumant des champs aussi variés que la conception de protocoles, l’amélioration d’outils algorithmiques et les attaques. Les deux principales focales de cette étude sont : un protocole de co-signature prouvé irréfragable et un système de chiffrement authentifié à sécurité prouvée. Notre protocole de co-signature permet l’équité légale. L’équité légale est une nouvelle variante de la notion d’équité, ne reposant pas sur des tiers. Notre instanciation d’équité légale est construite à l’aide des signatures de Schnorr. Nous présenterons ég

Abstract:
The contributions of this thesis fall into three areas of certificateless cryptography. The first area is encryption, where we propose new constructions for both identity-based and certificateless cryptography. We construct an n-out-of- n group encryption scheme for identity-based cryptography that does not require any special means to generate the keys of the trusted authorities that are participating. We also introduce a new security definition for chosen ciphertext secure multi-key encryption. We prove that our construction is secure as long as at least one authority is uncompromised, and s

Internet users rely on the availability of websites and digital services to engage in political discussions, report on newsworthy events in real-time, watch videos, etc. However, sometimes those who control networks, such as governments, censor certain websites, block specific applications or throttle encrypted traffic. Understandably, when users are faced with egregious censorship, where certain websites or applications are banned, they seek reliable and efficient means to circumvent such blocks. This tension is evident in countries such as a Iran and China, where the Internet censorship infr

Abstract:
Energy consumption by various modern symmetric key encryption protocols (DES, 3-DES, AES and, Blowfish) is studied from an algorithmic perspective. The work is directed towards redesigning or modifying the underlying algorithms for these protocols to make them consume less energy than they currently do. This research takes the approach of reducing energy consumption by parallelizing the consecutive memory accesses of symmetric key encryption algorithms. To achieve parallelization, an existing energy complexity model is applied to symmetric key encryption algorithms. Inspired by the popular DDR

Dans cette thèse, nous nous focalisons sur les problématiques liées au respect de la vie privée dans les services NFC ainsi qu’à la protection des données privées et secrets des applications mobiles dans les environnements d'exécution de confiance (TEE).

Abstract:
In a digital world, users’ Personally Identifiable Information (PII) is normally managed with a system called an Identity Management System (IMS). There are many types of IMSs. There are situations when two or more IMSs need to communicate with each other (such as when a service provider needs to obtain some identity information about a user from a trusted identity provider). There could be interoperability issues when communicating parties use different types of IMS. To facilitate interoperability between different IMSs, an Identity Meta System (IMetS) is normally used. An IMetS can, at least

Inom varje verksamhet förekommer det alltid någon form av projektplanering när man vill bedriva sin verksamhet på en ny marknad. Dessa typer av förberedelser görs på olika sätt och utmaningen för företagen blir att använda sig av rätt etableringsstrategi. För att lyckas med implementering av ett projekt, på respektive marknad som organisationer verkar på, är en utav framgångsfaktorerna att ha en tydlig och genomtänkt metod. Företaget Beta erbjuder molnbaserade tjänster inom tullhantering där man skapar lösningar som hjälper andra företag att hantera sina tullärenden. A

Abstract:
Freedom of speech and the right to privacy are maybe the most important elements of a modern society, yet the rights are often violated. This fact was the main reason for writing this thesis covering P2P network models, anonymity, censorship resistance and their use in real P2P networks and publishing systems. We discuss their effectiveness and suitability for specific purposes, but also the security considerations of their use. The second part of this thesis presents the LSPP publishing protocol, which is an library implementation of an anonymous censorship resistant P2P network. Finally, we

La recherche de nouveaux groupes autres que le groupe multiplicatif pour concevoir des protocoles plus constructifs en cryptographie est devenue un défi depuis 2000. Plusieurs groupes ont émergé tels que le groupe des points rationnels d'une courbe elliptique et la Jacobienne d'une courbe hyperelliptique. De plus, les couplages sont devenus des outils encore plus pratiques pour concevoir de nouveaux protocoles en cryptographie tels que le chiffrement basé sur l'identité et la signature courte.

Il lavoro è stato suddiviso in tre macro-aree. Una prima riguardante un'analisi teorica di come funzionano le intrusioni, di quali software vengono utilizzati per compierle, e di come proteggersi (usando i dispositivi che in termine generico si possono riconoscere come i firewall). Una seconda macro-area che analizza un'intrusione avvenuta dall'esterno verso dei server sensibili di una rete LAN. Questa analisi viene condotta sui file catturati dalle due interfacce di rete configurate in modalità promiscua su una sonda presente nella LAN. Le interfacce sono due per potersi interfacciar

Abstract:
Tendering is a method for entering into a sales contract. Numerous electronic tendering systems have been established with the intent of improving the efficiency of the tendering process. Although providing adequate security services is a desired feature in an e-tendering system, current e-tendering systems are usually designed with little consideration of security and legal compliance. This research focuses on designing secure protocols for e-tendering systems. It involves developing methodologies for establishing security requirements, constructing security protocols and using formal

Abstract:
As the acceptance and popularity of wireless networking technologies has proliferated, the security of the IEEE 802.11 wireless local area network (WLAN) has advanced in leaps and bounds. From tenuous beginnings, where the only safe way to deploy a WLAN was to assume it was hostile and employ higherlayer information security controls, to the current state of the art, all manner of improvements have been conceived and many implemented. This work investigates some of the remaining issues surrounding IEEE 802.11 WLAN operation. While the inherent issues in WLAN deployments and the problems of the
