Abstract:

This master thesis studies the possibilities of using a radio-router protocol in order to increase the quality of service in dynamic tactical network environments. We cover three radio-router protocols with emphasis on Dynamic Link Exchange Protocol (DLEP). Many applications, such as voice and video communication, have bandwidth and latency requirements which need to be fulfilled in order to provide a sufficient level of quality. This poses a problem in tactical network environments where links are typically dynamic and both bandwidth andlatency can vary. A radio-router protocol can alleviate

Fuel cell technology has undergone significant development in the past 15 years, spurred in part by its unique energy conversion characteristics; directly converting chemical energy to electrical energy. As fuel cell technology has past through the prototype/pre-commercialisation development, there is increasing interest in manufacturing and application issues. Of the six different fuel cell types pursued commercially, the Proton Exchange Membrane (PEM) fuel cell has received the greatest amount of research and development investment due to its suitability in a variety of applications.

Dans cette thèse, nous analysons le protocole IKEv2 à l'aide de trois outils de vérification formelle : Spin, ProVerif et Tamarin. Pour effectuer l'analyse avec Spin, nous étendons une méthode existante de modélisation. En particulier, nous proposons un modèle de la signature numérique, du MAC et de l'exponentiation modulaire, nous simplifions le modèle d'adversaire pour le rendre applicable à des protocoles complexes, et nous proposons des modèles de propriétés d'authentification. Nos analyses montrent que l'attaque par réflexion, une attaque trouvée par une précédente analyse, n'existe pas.

Abstract:

It is well known that the transport layer protocol TCP has low throughput and is unfair in wireless mesh networks. Transport layer solutions for mesh networks have been primarily validated using simulations with simplified assumptions about the wireless network. The WiFu Transport framework complements simulator results by allowing developers to easily create and experiment with transport layer protocols on live networks. We provide a user-space solution that is flexible and promotes code reuse while maintaining high performance and scalability. To validate WiFu Transport we use it to build Wi

One of the most crucial factors that e-commerce protocols should address is a fair exchange. In this research, an advanced method of cryptography coupled with the pay per use technique is used. A new electronic commerce protocol for the exchange of commodities is introduced. The proposed new protocol guarantees both features while addressing the main drawbacks associated with other related protocols. The new suggested e-commerce protocol is composed of two stages: pre-exchange and exchange stages. When the suggested new protocol is analysed with scrupulous protocol analysis, it attains fair ex

Abstract:

The importance of an authenticated key exchange (AKE) protocol has long been known in the field of cryptography. Two of the questions still being asked today are (1) what properties or features does a secure AKE protocol possess, and (2) How does one, in a step by step fashion, create a secure AKE protocol? This thesis aims to answer these two questions. The thesis contains two parts: one is a survey of previous works on the desired features of the Station-to-Station (STS) protocol, and the other is a study of a previously proposed design methodology in designing secure AKE pro

Abstract:

Secure communications over the Internet are typically established by first running an authenticated key exchange protocol, which computes a secret key between two users, which is then utilised in an encryption protocol. In this work we examine novel security properties of the most prominent communications protocols, including the Transport Layer Security and Secure Shell protocols. We introduce new security frameworks for analysing security properties of protocols involving negotiation, multiple ciphersuites, long-term key reuse, and time synchronisation.

Such methods formalize the operational semantics of a protocol, laying the base for protocol verification with automatic model checking tools.

Abstract:

Denial-of-service (DoS) attacks are a growing concern to networked services like the Internet. In recent years, major Internet e-commerce and government sites have been disabled due to various DoS attacks. A common form of DoS attack is a resource depletion attack, in which an attacker tries to overload the server's resources, such as memory or computational power, rendering the server unable to service honest clients. A promising way to deal with this problem is for a defending server to identify and segregate malicious traffic as earlier as possible. Client puzzles, also known as proofs o

Abstract:

This thesis analyzes Application Layer security protocols for certificate enrollment and management. EDHOC, Ephemeral Diffie-HellmanOver COSE, is a recently developed key exchange protocol whichis designed to provide authentication and key-exchange functionality with compact message sizes and minimum round-trip-time. The workof this thesis extends the EDHOC protocol with a certificate enrollment functionality, targeting IoT constrained devices and it has been implemented for analysis and evaluation purposes. The main scope of this document is to study the security, performance and scalability

碩士<br>國立臺灣大學<br>電機工程學研究所<br>92<br>When the Internet has grown in the past ten years, more and more people communicate with their friends over the Internet. But Internet does not provide privacy; this means that a perpetrator may observe confidential data when the data traverses the Internet. A perpetrator may also modify data traversed the Internet, and we loss data integrity. Things can be worse; a perpetrator may pretend you to send data to others. Thus, some security mechanisms must be used to prevent the above situation from happening IP Security (IPSec) is a network-layer protocol. By im

Before having access to the computer resources in remote site, it is one of the important issues in network security considerations to have a mutual authentication of the communicating entities. We proposed a new method of password authentication and key exchange protocol with smart card in this paper. The proposed scheme has the following characteristics: (1) it is not required for the server to store any authentication data

But, there are so many cheating events in internet auctions, which will cause the consumers to doubt of the feasibility of online shopping and obstruct the development of internet auctions. Facing the increasing cheating problems of internet auctions, some major auction websites guarantee their customers against all lost and bring out some policies. However, these policies have some deficiencies, so it is necessary to design a f

碩士<br>朝陽科技大學<br>資訊工程系碩士班<br>97<br>The introduction of the Internet era also means the dawn of mass threats of e-virus and hackers. Thus, the most appealing element of three-party communication would be the minimizing need of the session key in each user. All recent studies about the three party communications have been concentrating on the safety reliance of public key cryptosystem on the authentication server between each two parties. Yet, this method is prone to forgery identity and password guessing attacks. Therefore, some claimed that the bypassing of public key exchange protocol on authe
