Enabling Encryption on HKU Wireless LAN Network Interface Cards

We are delighted to inform you that a procedure for enabling security for the HKU Wireless LAN (WLAN) service is now available.  This means that if you use the HKU Wireless LAN to connect to the network, you can now send encrypted messages or data without the fear of someone eavesdropping on your communications.  Encryption or decryption is especially important in wireless communications. This is because wireless circuits are easier to "tap" than their hard-wired counterparts.

The HKU Wireless LAN service has been extended to 33 centrally time-tabled classrooms on the Main Campus in October 2000. Currently, a total of 59 WLAN Access Points have been installed in 19 different buildings and open areas.  The locations are published on our Centre's webpage.

Based on the encryption technology, the WLAN service is highly secure and is capable of providing a 128-bit Wired Equivalent Privacy (WEP) security in the communication between the wireless network interface card (NIC) and the Access Point. Data will be decrypted at the Access Points.

Users of the WLAN service can now make use of this security feature by downloading a secret encryption key from the University Intranet System (UIS) and configure their PCs for encrypting their wireless communications. A detailed procedure found by following the web links : http://www.its.hku.hk -> Network Connection -> Wireless Local Area Network.
