Hardwarové kryptografické moduly pro zabezpečení LAN / Hardware cryptographic modules for LAN securityLoutocký, Tomáš January 2008 (has links)
The thesis deal with the problems of virtual private network (VPN). The first part of the thesis is focused on the description of the basic terms of computer security which are useful for better understanding the other parts. There is a description of VPN technology and its separation of VPN by various aspects in the second part of the thesis. The next chapter is dedicated to the description of realization of VPN by using IPSec. There is shown how to secure laboratory network by using of the products of the Safenet Company in the practical part of the thesis. There are also stated the modular techniques how to use products in the network in practical part. Some of the modular techniques describe security weaknesses of the products which are possible to exploit in the laboratory network and they also describe the ways how to protect them against misusage.

Traffic Accident Prediction Model Implementation in Traffic Safety ManagementWen, Keyao January 2009 (has links)
<p>As one of the highest fatalities causes, traffic accidents and collisions always requires a large amounteffort to be reduced or prevented from occur. Traffic safety management routines therefore always needefficient and effective implementation due to the variations of traffic, especially from trafficengineering point of view apart from driver education.Traffic Accident Prediction Model, considered as one of the handy tool of traffic safety management,has become of well followed with interested. Although it is believed that traffic accidents are mostlycaused by human factors, these accident prediction models would help from traffic engineering point ofview to enlarge the traffic safety level of road segments. This thesis is aiming for providing a guidelineof the accident prediction model implementation in traffic safety management, regarding to trafficengineering field. Discussion about how this prediction models should merge into the existing routinesand how well these models would perform would be given. As well, cost benefit analysis of theimplementation would be at the end of this thesis. Meanwhile, a practical field study would bepresented in order to show the procedures of the implementation of traffic accident prediction model.The field study is about this commercial model set SafeNET, from TRL Limited UK, implemented inRoad Safety Audit procedures combined with microscopic simulation tool. Detailed processing andinput and output data will be given accompany with the countermeasures for accident frequencyreduction finalization.</p>
