SecurID server
Each time an end user connects to the specialized-HTTP server
running on the Firebox on port 4100, a Java-enabled applet opens

are DES-encrypted using a secret key shared between the Java
client and the Firebox. The Firebox then decrypts the name and
password to create a RADIUS PAP Access-Request packet, and
then sends it to the configured RADIUS server.
