CAS (Central Authentication Service) 
The Hilton Group Corporation developed the High Speed Internet Access (HSIA) service to provide Internet access 
service across its entire Hilton Group hotels. In order to use the HSIA, hotel guest(s) must be authenticated through 
the proprietary CAS. The CAS performs both user authentication and accounting. 
 
Figure 5-3 CAS Example 
The following summarizes the communication steps before Internet access is allowed. 
Step 1. 
A hotel guest launches a web browser. 
Step 2. 
The VSG redirects the guest’s web browser to a login screen at CAS.
 
Step 3. 
The guest enters the provided access information. 
Once authentication is successful, CAS informs VSG to allow Internet access to the guest.
