Design, implementation and analysis of a theft-resistant password manager based on Kamouflage architecture
2015
Masteroppgave informasjons- og kommunikasjonsteknologi - Universitetet i Agder, 2015 As a solution for helping companies and users in the constant security dilemma of obtaining and using passwords in the securest ways possible, password managers have become custom around the globe. The design architecture on what development of password managers are based on, preserving authenticity, usability and reliability are principles that keep systems secure and defend against attacks or unfortunate circumstances. The design principles however, have changed little over time. After researching password managers and analyzing overall security, we use our findings to develop a design based on the implem…
Clustered File Type Identification
2015
Masteroppgave informasjons- og kommunikasjonsteknologi - Universitetet i Agder, 2015 This thesis examines the possibility of expanding the current field of research for file type identification in Digital Forensics. A proposed solution is presented where unsupervised clustering and supervised classification are combined. The experimentation of the proposed solution increases the speed of file type identification, however with a decrease of total identification accuracy. A technique of unsupervised continuous learning is also presented, effectively making the proposed solution capable of adapting to the environment by learning from the test data while performing file type identification. In …
LTE- in Unlicensed Band: Medium Access and Performance Evaluation
2015
Masteroppgave informasjons- og kommunikasjonsteknologi - Universitetet i Agder, 2015 Long Term Evolution (LTE) technology is challenged by high data rate demanding services and increasing number of mobile phones which are equipped with Wi-Fi access capability. To respond to this challenge, 3rd Generation Partnership Project (3GPP) initiated a Study Item (SI) which investigates the co-existence of Wi-Fi and LTE technologies in the same unlicensed 5 GHz band. Given that Wi-Fi and LTE are originally designed to operate in totally different bands, unlicensed and licensed, it is difficult to achieve this coexistence for these two incompatible access technologies. Accordingly, 3GPP introduces the…
On-the-Fly Establishment of Multi-hop D2D Communication based on Android Smartphones and Embedded Platforms: Implementation and Real-Life Experiments

Determining gastrointestinal tract dysbiosis using machine learning techniques
2015
Masteroppgave informasjons- og kommunikasjonsteknologi - Universitetet i Agder, 2015 This thesis explores machine learning techniques for the purpose of determining gastrointestinal tract dysbiosis. Dysbiosis is an unbalance of bacteria flora. Stool sample analysis of relevant bacterias can be used in "diagnosis" of this condition. The problem is how to best classify dysbiosis from a healthy balance of bacteria. Pattern recognition methods could be used to create a diagnostic decision support system. The approach includes comparisons between classifiers with the additional use of feature reduction techniques. Experiments show that the accuracy varies significantly depending of which classif…
Neighbor and Service Discovery Protocols with Security Enhancement for Device-to-Device Communication in LTE{LTE-A Cellular Networks
2015
Masteroppgave informasjons- og kommunikasjonsteknologi - Universitetet i Agder, 2015 Device-to-Device (D2D) communication has become one of the most popular topic in the 5th generation (5G) mobile communication technology. D2D offers opportunities for access to services through direct neighbor device connection with or/and without base station (BS) assistance. Some of the possible improvements using D2D communication include high data rate, network offloading and range extension, as well as commercial and social proximity services networking. Although a lot of studies exist in the research community, D2D communication with one of the end users are located outside the cellular network covera…
Software Development Process Improvement in Datacom Platform
2008
Masteroppgave i Informasjons- og Kommunikasjonsteknologi 2008, Universitetet i Agder, Grimstad Ericsson Mobile Platform (EMP) is responsible of the development of a software platform and also to some extend responsible for related hardware parts. EMP is developing the data communication parts of the platform which is used by EMP customers. The platform development is done in large development programs and each program span over a quite a long time period. However, as we see every day in the shops mobile phone manufactures are launching new models more or less every month. EMP has many different mobile phone manufactures on its customer list and in order to meet their requirements/wishes, th…
Security in NFC with Wi‐Fi Protected Setup as a use
2008
Masteroppgave i Informasjons- og Kommunikasjonsteknologi 2008, Universitetet i Agder, Grimstad Near Field Communication is a short‐range communication channel that is one of the most promising technologies around. One of the purposes for this technology is to simplify first‐time connections to other wireless technologies, like Wi‐Fi and Bluetooth. In this thesis we will incorporate Near Field Communication in an 802.11 network for a hotel. We will show how this technology will be used in a scenario like this, where guests will get easily access to the hotels wireless network through their personal devices. NFC will be used for initiation, authentication and exchange of configuration setting…
Resource Discovery and Security in Distributed systems
2007
Masteroppgave i informasjons- og kommunikasjonsteknologi 2007 - Universitetet i Agder, Grimstad To be able to access our files at any time and any where, we need a system or service which is free, has enough storage space and is secure. A centralized system can handle these challenges today, but does not have transparency, openness and scalability like a peer to peer network has. A hybrid system with characteristics from both distributed and centralized topologies is the ideal choice. In this paper I have gone through the basic theory of network topology, protocols and security and explained “search engine”, “Middleware”, “Distributed Hash Table” and the JXTA protocol. I then have briefly e…
