WEP security and encryption
The Nokia A032 can provide access security
and eavesdropping protection using a method
called
wire equivalent privacy
(WEP). WEP is
specified as an option under the IEEE802.11
standard. It is designed to protect the wireless
portion of a network.
WEP provides:
• Secure data encryption, using a secret
key
(or password) which is known only by a
specific group of users.
• Sophisticated network access control, to
restrict access to a specific group of wireless
users, or be applied on a per-user basis.
Using WEP
A wireless client must go through an
authentication process before the access point
will allow any connection to occur.
This is done using a challenge-response
method, which means that outsiders cannot
find out the value of the encryption key.
Encryption keys
The Nokia A032 provides two basic approaches
for encryption key management:
• Shared WEP keys – All wireless clients in a
group use the same key.
• Personal WEP keys – Each wireless client
has an individual key.
You can use the Nokia
A032 in conjunction
with other vendors’
wireless LAN clients
which adhere to the
IEEE802.11 standard.
