Būsto kompiuterinės sistemos saugos sistemos sudarymas ir tyrimas / Creation and analysis of security system for house computer system

Žilinskas, Ignas 04 November 2013 (has links)
Šiame darbe apžvelgiamos būsto kompiuterinės sistemos saugumo problemos ir siūlomi būdai joms išspręsti. Išanalizavus egzistuojančias sistemas buvo pastebėta, kad tarp sistemos įtaisų siunčiami duomenys nėra šifruojami ar kitu būdu apsaugomi. Tai leidžia šiuos duomenis perimti ir suklastoti, taip paveikiant sistemos darbą. Kita problema – naudojamas belaidis ryšys. Jei sistema neatpažįsta belaidžio ryšio atakos, ji yra pažeidžiama. Šiame darbe duomenų apsaugai siūlomas KeeLoq šifravimas. Tyrimas rodo, kad šis šifravimo būdas yra efektyvus būsto kompiuterinėse sistemose. Taip pat šiame darbe sukurta belaidžio ryšio posistemė, kuri įgalina būsto kompiuterinę sistemą atpažinti belaidžio ryšio atakas ir į jas tinkamai reaguoti. Atliktas tyrimas rodo, kad būsto kompiuterinė sistema šios posistemės pagalba teisingai aptinka visas belaidžio ryšio atakas. / This paper presents gaps in the house computer systems security and suggests a way to solve it. It was noticed, that communication among house computer system’s devices isn’t encrypted or secured in any other way. This situation enable attacker to get data, sent among devices, and use it to affect the system. Another problem is attacks against wireless communication. If system’s devices can’t detect such attacks, it is vulnerable. This paper suggests using KeeLoq encryption to make communication safer. Research shows, that this type of encryption is effective in house computer system. There was created subsystem of wireless communication in this work. It enables house computer system to identify wireless attacks and respond to it properly. Research shows, that this subsystem correctly detects attacks and always help system to take right actions.

Bubník, Karel January 2010 (has links)
This work describes the design, construction a performance of such a complete wireless pager suitable for health care centers, rest homes, home application, for example for calling an attendant. This appliance is designed to be easy to attendance. A wireless transceiver is simplified and is attended only by one button. A wireless receiver also doesn't require a complicated manipulation. The aim is to create pager, which will be an useful assistant thanks to its price and simple construction.
