System archetypes and dynamic stories on information security risks in the transition to integrated operations in the oil and gas industry
2006
Masteroppgave i informasjons- og kommunikasjonsteknologi 2006 - Høgskolen i Agder, Grimstad From a situation where the drilling and production platforms were solely run on site (offshore), the industry is now working on establishing land based control systems to decrease production costs, and consequently increase income. The ongoing project Integrated Operations (IO) (http://www.olf.no/io/) expects to yield up to 30% cost reduction and a 10% increase in production. One of the key factors to achieve these goals is reliable and secure information technology between offshore and onshore installations. Information security incidents can cause serious damage on personnel, production and install…
Video on Demand med Digital Rights Management og publisering av innhold for VoD tjenester
2003
Masteroppgave i informasjons- og kommunikasjonsteknologi 2003 - Høgskolen i Agder, Grimstad Oppgaven ser nærmere på hvordan en kan beskytte digitaltinnhold for en Video on Demand tjeneste med Digital Rights Management og hvordan en enkelt kan publisere innhold for en slik tjeneste. Det blir skissert løsninger for å automatisere publiseringen av innhold. Andre aspekter ved oppgaven er hvilke logging funksjonalitet som finnes i streamingserveren og fordeler/ulemper ved ulike distribusjonsalternativer for digitaltinnhold over Internett. Distribusjonsalternativene som testes er ulike streaming og nedlastingsalternativer med hensyn på oppnåelig videokvalitet, brukervennlighet og fra aksesslevera…
A feasibility study and recommendation of technology and solutions for wireless monitoring of biomedical data
2003
Masteroppgave i informasjons- og kommunikasjonsteknologi 2003 - Høgskolen i Agder, Grimstad This report contains the results of a study on wireless remote monitoring technology that has been conducted for Contel AS, though it applies to a much wider audience. The study was started because there was need for, and interest in, broad sighted information about the subject. This information has been collected and organized into this report, in addition to our own evaluations and proposals. Remote monitoring of patients is an interesting subject. There is a lot of ongoing research and development, and many exciting new ideas and technologies are under way. This technology has the potential to cha…
Sikring av IP-basert managementtrafikk : sammenlikning av SNMPv3, IPSec og TLS
2003
Masteroppgave i informasjons- og kommunikasjonsteknologi 2003 - Høgskolen i Agder, Grimstad Denne hovedoppgaven tar for seg ulike måter å sikre IP-basert nettverksmanagement trafikk. De mest vanlige metodene for nettverksmanagement, Simple Network Management Protocol (SNMP) og telnet, ble i sin tid utviklet uten særlig tanke for sikkerhetsproblematikk. SNMP har derfor vært gjenstand for flere revisjoner med hovedmål å tillegge sikkerhetsmekanismer. Kun den siste utgaven SNMPv3, har lykkes tilfredstillende i dette arbeidet. SNMPv3 brukes imidlertid i svært lite grad da den krever installasjon av dyre og komplekse komponenter på både nettverksutstyr og managementkontrollsentre. Vi har derfor …
The use of PKI in a Smart House solution
2003
Masteroppgave i informasjons- og kommunikasjonsteknologi 2003 - Høgskolen i Agder, Grimstad The intention of this thesis project is to evaluate the security and capabilities offered by a PKI enabled network between a Smart House and different vendors, such as electric Utility Company, Security Company, Fire brigade and the owner of a Smart House. Then I will show how a third party signed certificates can be used for such networks. It includes the use of public key cryptography, digital signatures, certificates, and certificate authorities (Trusted Third Party). How to apply PKI security services in different ways with different requirements is the main issue of this work. One of the end ent…
A feasibility study of new RFID applications
2004
Masteroppgave i informasjons- og kommunikasjonsteknologi 2004 - Høgskolen i Agder, Grimstad The introduction of Radio Frequency Identification represented quite a revolution to the various areas of industry and business, focusing on the process of marking items for automatic identification. RFID offers similar functionality as the well established barcode, but with major additional advantages. These are in short read/write capability, memory, and operation independent of free line of sight between reader and tag. Enhanced production techniques also seems to contribute to lower production cost and thus cost per unit boosting the research on new and promising RFID applications. Other factors …
Investigation of spatial exposure control in 3G cellular/wireless system in conjunction with access authentication
2004
Masteroppgave i informasjons- og kommunikasjonsteknologi 2004 - Høgskolen i Agder, Grimstad The number of services provided by the mobile system has increased in an amazing rate. Technology has been the driving part for services like SMS, Chatting, and lately the new MMS standard with mobile terminals and integrated cameras. As the technology evolves, so does the mobile terminals and the services with them. The hype for the next decade may be position aware services. As GPS modules are getting cheaper, and more and more terminal providers integrate this chip with their equipment, the usage of such applications will explode. In the eyes of the security conscious operators, this new technolog…
Study of aspects in electronic patient journal relevant to the medical office agreement
2003
Masteroppgave i informasjons- og kommunikasjonsteknologi 2003 - Høgskolen i Agder, Grimstad Keeping track of the condition of a patient is and always will be important in order for a doctor to give the best diagnosis and keeping the patient as healthy as possible. Earlier the patient journals were stored at the local medical office, and were not possible to get your hands on if you were in another part of the country, or county for that matter. Electronic Patient Journal aims to change this for good. When, or if, the medical offices start using Electronic Patient Journal, viewing and getting the latest update on a journal will no longer be a problem for the doctors, making their job easier.…
Estimated accuracy of location in mobile networks using E-OTD
2002
Masteroppgave i informasjons- og kommunikasjonsteknologi 2002 - Høgskolen i Agder, Grimstad This master thesis was performed for Telenor Research and Development, department Fornebu, Norway. The assignment was to evaluate the accuracy of the Enhanced Observed Time Difference (E-OTD) location method. Location related services are described as the next revolution on services and functionality in the mobile network. Location technology will help the operator to estimate the location of a mobile station in the network. But different location services require different accuracy of the location estimate. It is therefore important to find out what location method(s) is suitable for the operators n…
Handover i Mobil IP i fremtidens mobile Internett
1999
Masteroppgave i informasjons- og kommunikasjonsteknologi 1999 - Høgskolen i Agder, Grimstad Denne rapporten omhandler en utredning av handover i Mobil IP og hvordan den kan forbedres slik at den er mer egnet til framtidens mobile Internett. Begrepet handover omfatter situasjonen som oppstår når en mobilnode flytter seg fra et sted til et annet, og må bytte tilknytning for å fortsatt kunne ha kontakt med nettverket. Rapporten begynner med en innføring av de aktuelle teknologiene som er viktige for gjennomføring av oppgaven. De viktigste teknologiene er protokollen Mobil IP, og neste generasjons Internett (IPv6). Mobil IP er en protokoll som bygger på Internett Protokollen (IP) og gjør mobili…
