Security in the wireless network: Encryption 
Any network, be it wired or wireless, is exposed to the risk of eavesdropping.
Connecting your local network to the public network exposes your data and applications 
to some considerable risk. In the same way as with an individual connection, you should 
always install a virus scanner to protect your PCs against malicious covert external 
attacks, e.g. via e-mail. 
These virus scanners, however, do not provide any protection against unauthorised 
access from outside (hackers). To counter this risk, Gigaset data products offer various 
encryption procedures that largely rule out unauthorised access (hacking) to your 
wireless network.
WEP encryption
WEP encryption (Wired Equivalent Privacy) encodes data for sending using a key that 
you have defined. On the recipient's side, the same key is used to re-arrange the data so 
that it is available in the same format as it was prior to transmission. Recipients who do 
not know this key cannot read the content of this data stream or can only read it with a 
great deal of technical effort. 
There are two security levels for calculating the encryption key:
u 64-bit mode
u 128-bit mode
WPA encryption
WPA is a new standard-compliant solution for greater security in wireless networks. WPA 
is intended to replace the existing WEP standard (Wired Equivalent Privacy) and offers 
more reliable encryption and authentication methods.
With your Gigaset USB Adapter 300 you can use WPA encryption independently of the 
operating system you have in use. WPA encryption is particularly recommended where 
the highest security is required.
