Security issues should always be carefully considered to ensure the secure
transmission of data in both wired and wireless LANs. In current wireless systems,
for example, access points need to authenticate wireless stations to prevent
unauthorized access to the network. Authentication is a service that confirms the
identity of an entity, such as a user or a computer, or confirms the origin of a
transmitted message.
The Nokia C110/C111 supports the wired equivalent privacy (WEP) protocol to
provide security equivalent to that of a wired local area network. The WEP
protocol utilizes the RC4 algorithm with an up to 128-bit secret key, which
encrypts data before it is transmitted over the radio waves. This provides
protection against intruders and unauthorized access to the data. When the
wireless stations in a wireless LAN wish to communicate using WEP, they must
have possession of the same secret key.
The Nokia C110/C111 is equipped with an integrated smart card reader. Smart
cards and smart card readers provide a tool for managing secure user
