Zero knowledge protocols is a lesser known type of protocol that can be used for identification. These protocols are especially designed not to reveal any information during an identification process that can be misused later on, neither by the one who should be convinced of the identity of the user, nor by anyone else that is eavesdropping. Many of these protocols are also especially designed for implementation in smart cards. The more common type of card with a magnetic stripe has during the last few years become more susceptible to attacks since they are easily copied. Smart cards combined with a secure identification protocol has been predicted to be the solution to this problem.

AbstractPolitical Science, level III thesisSpring semester 2010Author: Emelie AlfredssonSupervisor: Tomas Mitander"A Changed Leadership? - A study of the EU leadership from a institutional standpoint, related to multilateral environmental negotiations"The EU has for a relatively long time considered itself a leader in the environmental policy area as a whole as well as in multilateral environmental negotiations. This study attempts to classify and identify the European leadership with the purpose of relating it to the institutional framework of the Union. The treaties of the European Union decide its ability to act and its institutions the right to engage in different policy areas, the environmental area being the focus of this study. With the recent ratification of the Lisbon treaty this study aims to make out if the type of leadership the Union showed during the Kyoto negotiations has changed with the new treaty, into a new type during the COP-15 meeting in Copenhagen.

Climate change is one of the most difficult problems that humans have to deal with. Today, the evidence of human effects on the climate change and the rise of temperature on earth are strong. It is extremely important that all countries get together and cooperate in order to be able to solve the problem with climate change. One step in the work on climate changes is the Convention on Climate Change, which was agreed on in 1992. The Convention on Climate Change resulted in the Kyoto Protocol in 1997. The Kyoto Protocol is an agreement between a number of industrialized countries to limit or reduce the green gas emissions.

The idea for this project was initiated together with one of the leaders in the forest, paper and packaging industry. To get through an A/R CDM process the company is exposed to the risk of failing the process or that the overall costs will exceed the benefits of the project. This would delete the incentives to invest in GHG removals compared to purchasing emission allowances on the carbon market. The questions that have been raised and needs clarification in the thesis are the following:? From a company perspective, what are the incentives for implementing Forest Clean Development Mechanism (CDM) projects?? What is a likely financial outcome of a reforestation CDM project on degraded land in the Guangxi province of the Peoples Republic of China?? When does an investment like this break even with the cost of buying market based carbon emission allowances? The objective of this master thesis is to carry out a research about the incentives for forest, paper and packaging companies to invest in reforestation through the clean development mechanism.

The original promise behind the Internet Protocol was to deliver data from a sender to the receiver using a best-effort approach. This means that the protocol makes no guarantees except that it will try to deliver the data to the destination. If some problem occurs the packet may be discarded by the network without any notice. No guarantees are made regarding the time it takes to deliver the data, the rate at which data will be delivered or if data is delivered in the same order it was sent. The best-effort approach is arguably the reason behind the success of the Internet Protocol and is what makes IP scalable to networks the size of the Internet.

The last couple of years the use of mobile devices such as mobile phones and PDAs has increased tremendously. Most of the these devices have their own protocols for synchronising data and this has given rise to a need for a standard synchronisation protocol, SyncML. This thesis compares this protocol against the existing ones. The comparison shows that the preferred choice is SyncML. Also an application using SyncML has been developed.

The goal with this project was to achieve real-time synchronized video playback over the Internet, or in other words, that multiple clients play the same part of a video at the same time.The result shows how it is possible to build such a protocol, that gives a user experience that the video is synchronized between computers when playing a locally stored file, stream or video delivered using progressive download. This was achieved by designing, then role playing to find weaknesses, and at last implementing the protocols to see how they work in practice. By using such a protocol, it is possible to navigate and discuss around a video in for example a telephone conference, and be sure that everybody is looking on the same picture..

This report is the written part of a bachelorthesis on the computer engineering program atUniversity of Halmstad. The project was a cooperate project that where done together withFree2move Holding AB. Free2move is a company with eight employees in Sweden and four inMalaysia. The company is today developing Bluetooth modules and RFID chips. The market forthis kind of products is growing very rapidly, last year it grew 71 percent.

Internet grows, so it?s cracking, soon will all IPv4 addresses be allocated and a solution is urgently needed. The new protocol, IPv6 is the solution to this problem. With a size of 128 bits against IPv4s 32 bits gives IPv6 a huge amount of addresses to distribute. The security addition that may be added manually in IPv4 is the standard with the new protocol.

FlexRay is a new communication protocol which is fast, reliable and flexible and therefore can meet the increasing demands on data communication in the vehicle industry. The protocol is developed by an industrial consortium containing among  others BMW, Daimler Chrysler, Motorola and Phillips. Today (May 2009) Hägglunds is using CAN for data transmission in their systems. CAN is getting obsolete and has difficulties in coping with the increasing flow of communication. In this report FlexRay and its communication capacity is studied.

This report describes a bachelor thesis work performed at the cloud storage company CloudMe in Linköping, Sweden. The storage service provided by CloudMe allows users to access their files seamlessly from multiple units at the same time. In the cloud there is storage provided for contacts, calendar and e-mail, which is data nowadays normally used by smart phones.Exchange ActiveSync is a protocol developed by Microsoft which, among much more, provides functionality to synchronize the previously described data. This protocol is supported by the smart phone developers and the ability to synchronize over the exchange protocol is implemented in products by default. Due to this fact it would be preferable to implement support for synchronization from CloudMe to phones over this protocol.

HMS Industrial Networks AB is in need of changing a communications solution that iscurrently based on an ASIC. This will be achieved by moving the communications solution toa FPGA with the help of the programming language VHDL. By doing this, it is possible toreduce the need for specific circuits, get a more flexible platform and thus get a cheapersolution.This report describes a solution for how to move a network protocol from an ASIC to anFPGA. The report shows that the network slave device is working under the guidelines forthis project. This means that it is quite realistic to implement a fieldbus protocol on an FPGA,using VHDL and to maintain the same functionality as the earlier communications solution..

In January 2005 the emission allowance system was introduced within the European Union and the first period ends at the end of 2007. The system was introduced in order to decrease the wastes of carbon dioxide and the system is a part of ratifying the Kyoto ?protocol which first period runs between 2008-2012.The idea of the system is to reduce the wastes of carbon dioxide where it costs less to do so and the expenses for the society therefore are as diminutive as possible. Different theories explain that companies can benefit from environment legislation and can depending on the company?s attitude gain competitive advantages improve its productivity and thereby increase its profitability.With this in mind, the study aims at examining how the introduction of the emission trade system has influenced Swedish smaller companies in the distant heating industry, with focus on the factors attitude, innovation, competition and profitability.

This study in Environmental Science examines the amendment of the EU-Directive on. Greenhouse gas emission allowance trading. The Directive is to be considered as a tool for fulfilling the obligations that the Union and its member countries have taken on through the 1997 Kyoto agreement together with the protocols proposed at that time. The flexible mechanisms of the protocol are intended as instruments for limiting the climatic changes arising from anthropogenic sources, emission allowance trading being one of these mechanisms. The results presented here consist primarily of an analysis of interviews with various experts in the field of emission control concerning the possibilities and problems attending the process of implementation.
