the network.WPA2 is the second generation of WPA
security and provides a stronger encryption mechanism
through Advanced Encryption Standard (AES), which is
a requirement for some government users.
802,1x authentication
Static WEP key is difficult to manage for when you
change the key, you will have to inform all others, and if
the key is disclosed in one of the places, the key can no
longer provide security. Besides, there’s severe security
loophole about static WEP encryption. The WEP key can
be decrypted after one person receives a specific
amount of data via wireless intercepting. 802,1x is
initially used for wired Ethernet authentication access to
prevent illegal users from accessing the network. Later,
it is found that 802.1x can better solve the wireless
network security problem. EAP-TLS of the 802.1x
successfully achieves the two-way authentication
between users and networks, i.e. can prevent illegal
users from accessing the network and can also prevent
users from accessing the illegal AP. 802.1x utilizes
dynamic WEP encryption to protect the WEP key from
being decrypted. To solve the publishing problem for
digital certification, people make some changes to TLS
authentication and TTLS and EAP come into exist, which
enable you to access the network by using the
traditional way of authentication: username and
password.
