Abstract

The wide spread acceptance of IEEE WLANs is a result of industrial standardization to ensure product compatibility and reliability among various manufacturers. Several WLANs solutions are available with varying characteristics and interoperability. The IEEE Standard 802.11 is one of the most widely adopted mechanisms for wireless LANs. It defines both physical (PHY) and medium access control (MAC) layer protocol however; it provides limited data confidentiality and has cumbersome procedure for key exchange. In response IEEE introduced a port based network access control standard 802.1x to authenticate and authorize devices interconnected various IEEE 802 LANs. 802.1x only defines authentication not the actual authentication method which allows the developers to construct their own algorithm and consequently a lot of wireless vendors implemented their own 802.1x adaptation such as MD5 Message Digest 5, TLS (Transport Layer Security), TTLS (Tunneled TLS), PEAP (Protected Extensible Authentication Protocol), LEAP (Lightweight Extensible Authentication Protocol) and others. This versatility in 802.1x adaptations has made it difficult for the WLANs users to choose an appropriate mechanism in relation to performance and security of networks. An effort has been made in [1] to carry out comparative analysis of IEEE authentication methods in different security combinations. This work supplements the efforts cited in [1] and incorporates more results in added network configurations. The paper finally recommends the users an appropriate IEEE authentication methods depending upon the need, requirements and security concerns.
