11	Inter-device authentication protocol for the Internet of Things Wilson, Preethy 18 May 2017 (has links) The Internet of things (IoT) recently blossomed remarkably and has been transforming the everyday physical entities around us into an ecosystem of information that will enrich our lives in unimaginable ways. Authentication is one of the primary goals of security in the IoT and acts as the main gateway to a secure system which transmits confidential and/or private data.This thesis focuses on a Device-to-Device Mutual Authentication Protocol, designed for the smart home network, which is an essential component of communication in the Internet of Things(IoT). The protocol has been developed based on asymmetric cryptography to authenticate the devices in the network and for the devices to agree on a shared secret session key. In order to ensure the security of a communications session between the devices, the session keys are changed frequently - ideally after every communication session. The proposed scheme has been programmed in HLPSL, simulated and its efficiency verified using the SPAN/ AVISPA tool. When SPAN substantiates the protocol simulation and the attacker simulation, the back-ends of the AVISPA tool verifies the safety and security of the proposed authentication protocol. The thesis also evaluates the protocol's security against the attacks successful against protocols proposed by other researchers. / Graduate / 0544 / 0984 / 0537 / pwilson1@uvic.ca Authentication Internet of Things (IoT) Smart Homes Smart Home Network AVISPA/SPAN AVISPA Internet Security Cryptography Encryption Asymmetric Cryptography Shared Session Key Private Key Public Key Cloud Fog Security HLPSL Quality Metrics Simulation Protocol Simulation Attacker Simulation Formal Verification Verification Multi-protocol Attack Reflection Attack OFMC CL-AtSe Communication Computing Mutual Authentication Device-to-device inter-device machine-to-machine Attacks
12	Data Encryption on a Network Luque González, Jorge, Arenchaga Fernandez, Ignacio January 2010 (has links) In this project you can find a study about different encryption algorithms, which are use to safeguard the information on messages over the network. We have developed a client-server application which will send information through the network which has to be secured. There are two kinds of encryption algorithms, the symmetric and the asymmetric key algorithms. Both were used to establish the communication, the asymmetric algorithm (RSA) is used to set up a symmetric key and then, all the communication process is done only with the symmetric algorithm (Blowfish). / En este proyecto encontraras un estudio sobre diferentes algoritmos de encriptación, que son usados para salvaguardar la información en mensajes por la red. Además hemos desarrollado una aplicación cliente-servidor que enviara información a través de la red de forma segura. Hay dos tipos de algoritmos de encriptación, los simétricos y los asimétricos. Ambos tipos de algoritmos son utilizados para establecer la comunicación, el asimétrico (RSA) es utilizado para establecer la clave del simétrico y a partir de entonces se utilizara exclusivamente el algoritmo simétrico (Blowfish). encryption decryption DES Triple-DES security serpent blowfish Diffie-Hellman RSA AES private key public key security attack brute force man-in-the-middle. encriptacion decriptacion DES Triple-DES seguridad serpent blowfish Diffie-Hellman RSA AES clave privada clave pública ataque fuerza bruta man-in-the-middle Computer Sciences Datavetenskap (datalogi) Telecommunications Telekommunikation Computer Sciences Datavetenskap (datalogi)
13	Odposlech moderních šifrovaných protokolů / Interception of Modern Encrypted Protocols Marček, Ján January 2012 (has links) This thesis deals with the introduction to the security mechanism.The procedure explains the basic concepts, principles of cryptography and security of modern protocols and basic principles that are used for information transmission network. The work also describes the most common types of attacks targeting the eavesdropping of communication. The result is a design of the eavesdropping and the implementation of an attack on the secure communication of the SSL protocol..The attacker uses a false certificate and attacks based on poisoning the ARP and DNS tables for this purpose. The thesis discusses the principles of the SSL protocol and methodology of attacks on the ARP and DNS tables.
