This report describes what wireless local area networks are and the use and configuration of them. These WLAN as they also are called can be used both in new installations and expansion of existing networks. Further on this report reveals security in this area. Security is …
The security solutions used in wireless home networks are examined in this report. Thegrowing number of wireless units have increased the need for reliable security solutions.This report aims to enlighten the reader about the fundamental technology used inwireless security …
This paper is a study and comparison between the two Wireless LAN (WLAN) standards HiperLAN/2 and IEEE 802.11a. WLANs are used instead or together with ordinary LANs to increase mobility in for example an office. HiperLAN/2 is an European standard developed by ETSI and the IEEEs …
I denna rapport undersöks WPS-funktionen då det uppmärksammats säkerhetshåli den. Intervjuer, tester och observationer har gjorts för att undersöka problemenmed WPS. De tester och intervjuver som gjorts indikerar att säkerhetsbristen i WPS-funktionen har säkrats upp med extra …
… roaming in a WLAN. It also provides a security analysis of the system that the wireless access point is part of. The reason for this is that Ericsson is selling an access point called the ABS 2200 aimed at the public hotspot market. The premise was that they wanted a …
En utredning av rättsläget, säkerhetsläget och säkerhetsmedvetandet vid användning av trådlöst hemmanätverk.
Användningen av trådlöst nätverk blev under början av 2000-talet mycket populärt bland privatpersoner, genom dess mobila fördelar, Tekniken medförde många fördelar, men också många nackdelar och frågan var hur många som verkligen hade blivit uppmärksammade på eller kände till …
Användandet av trådlösa nätverk breder ut sig mer och mer både bland företag och privatpersoner. För privatpersoner kan det vara skönt att slippa sladdarna som ett vanligt nätverk för med sig och för företag kan det trådlösa nätverket fungera som ett komplement till det vanliga …
säkerhet och GPU
Trådlosa nätverk är av naturen sårbara for avlyssning för att kommunikationen sker med radiovagor. Därfor skyddas trådlosa nätverk med kryptering. WEP var den första krypteringsstandarden som användes av en bredare publik som senare visade sig innehålla flera sårbarheter …
… to prevent these vulnerabilities by updating the affected computers. Also a wireless network with WEP encryption, which is insecure, has been detected and decrypted.
… placed intermittently along the railway. As the signals are transmitted wirelessly, problems may occur as the antennas get dirty or coated with ice and snow. To determine the effects of these coatings, several tests were performed examining the reflection coefficient S11, the …
