Information
Since the deployment of infamous Wired Equivalent Privacy (WEP), IEEE and vendors have developed a number of good security mechanisms to restore the public trust on WLANs. As a result, mechanisms, such as RSN, TSN, WPA, and TKIP, have seen the daylight. Unfortunately deploying the new features makes the system more complex. We now have enough security features for building obscure systems from them. The 'keep it simple' -principle is superseded by the new modified slogan. In WLAN networks 'Security through obscurity' has the potential to become 'obscurity through security'. The purpose of this paper is to assist in understanding complex wireless networks by collecting and summarising the publicly available information about WLAN security mechanisms. I will introduce the different WLAN security mechanisms from WEP through WPA to 802.11i. I will also provide a mind-map visualisation of the relations between different specifications and terms. The reader may use the map as assistance while reading this whitepaper. This paper summarises the flaws of WEP and how new security mechanisms fix or work around them. It serves as a basic introduction to the state-of-the-art security mechanisms in WLANs.
Questions
- Q01: Example question
- A01: Example answer
- Q02: How does DynamicWEP relate to all this?
A02: 802.11i specifies TSN (Transitional Security Network). It allows WEP devices to co-exists with RSN devices, which use for example TKIP or CCMP. Thus it is possible that dynamic WEP relates to 802.11i/TSN, or even WPA, which is a modified subset from 802.11i
- Q3: Would anyone care to add 802.1a/b/g/... MAC/PHY layer definitions here? Mucho thanks, never has understood if they share some protocol over the physical layer or not?
- Q4: How Wifi relates to all this? Not explained here?
