"Halfpipe Active Channel"- developing a secure communications protocol

With the advent of powerful multimedia capable mobile phones, the market for mobile services is flourishing. Zenterio AB's Halfpipe Active Desktop is a complete distributed mobile service platform a with a powerful server and platform-independent client. The communication between the client and server takes place over a GPRS-capable mobile network. The purpose of this thesis is to develop a Secure communications protocol for use between the Halfpipe Active Desktop client and server. This is done by determining requirements, analyzing candidate protocols and then by designing the final protocol.

Säkra kommunikationskanaler i en distribuerad heterogen miljö

The systems environments of today are often distributed and heterogeneous. These kind of systems have several advantages but also disadvantages. One problem is how to keep them secure.The security problems in these environments are mainly due to the communication between the connected computers. It is relatively easy to tap these communication channels from information. There is also a need for the possibility to secure these channels from modification of sent information and to be able to verify the sender and receiver of information in a secure manner.

Implementation av fältbuss ASIC i FPGA

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..

Digitala kommunikationer mellan VIDA och deras leverantörer

The Swedish forest industry has put a lot of resources in the development of digital communications in hopes of improving collaboration with suppliers. The purpose of this study was to investigate whether VIDA would benefit from using digital communication with suppliers. The survey was conducted as a questionnaire study among the company?s staff and its suppliers. The result indicated needs and interests to use digital communications in both groups. Young suppliers and suppliers on a distance showed the most interest in using digital communication. In terms of using these digital communications, the staffs and suppliers were most interested in information regarding transaction and forestmanagement plans.

Utvärdering av Near Field Communication och Certified Wireless USB: Säkerhet vid utveckling av applikationer

Today?s society is one where technological advances are made daily, which increases the need to stop and assess the risks against users? integrity when integrating new technology in contemporary systems all the greater. We have taken two technologies, Near Field Communication and Certified Wireless USB, whose envisioned area of use is to be integrated into mobile phones, and evaluated what security threats are revealed for the respective technologies. The threats against security have been identified through research of the standards and existing reports for each technology. Practical experiments have not been conducted on account of us not having access to any equipment to run such trials.

Kunskapsöverföring, Utvärdering och Lönsamhet - tre perspektiv på utbildning - en fallstudie av Axis Communications'' Academy

Vår studie är inriktad på att finna en heltäckande modell för lönsamhetsberäkningar på utbildning mellan företag. Genom en fallstudie har vi studerat Axis Communications' Academy, där Axis Communications utbildar sina kunder inom nätverkskameror. Vi har fört samman avkastningsberäkningar (RoI) med kunskapsöverföring och utvärdering av utbildning till en modell vi kommit att kalla Modell för Kunskapsöverföring, Utvärdering och Lönsamhet, KUL-modellen. Modellen har sammanfört tidigare forskning inom Knowledge Transfer och Human Resource Development, för att komplettera RoI. I modellen framgår att det går att mäta kunskapsöverföringen i en utbildning genom faktorerna Erfarenhet, Avstånd, Relation, Motivation, Reaktion, Implicitet och Specificitet.

Säkerhetsstandard för ett mjukvarubaserat säkerhetselement

Researchers today anticipate that in the near future, the majority of the owners of a smartphone will use it as a wallet, i.e. for contactless payment. The technology that enables contactless payment today is ?Near Field Communication? (NFC), which is increasingly embedded in smartphones. Applications like mobile payment between a phone and a terminal use NFC.

Säkerhet i Wireless Local Area Networks : En studie i säkerhetslösningar utförd på uppdrag av Saab Bofors Dynamics AB.

Saab Bofors Dynamics AB is looking for ways to let the employees work wireless in the future. The security in Wireless Local Area Networks (WLAN) has not been considered very reliable, but new standards and protocols have been developed to enhance the security in WLAN. Since most wireless components soon will have built in support for wireless communication, it is important to have a model to deal with secure wireless communication ready. This is necessary because it is important to protect the company?s information related systems, ensure contingency in the daily work and maintaining the trust of the market and the authorities.

Institutet beslag : vid brottsutredning

The purpose of this paper is to explore what objects that can be seized and how the management of a seizure should be conducted. Ability to take enforcement against an individual should be carefully weighed against the rights and freedoms that exist. Seizure is one of the various restraints that exist, and the regulation on which they appear is mainly in the Code of Judicial Procedure, Chapter 27th. To be able to apply coercive measures, it is fundamental prerequisite that a criminal investigation is initiated, but there exist some significant exceptions to this. There are also rules about who has the right to provide for the seizure, the decision can be taken by a prosecutor, an investigator, a police officer or, in special cases, the court.
