Abstract
This paper presents the design and implementation of headend servers for a downloadable conditional access system (DCAS) that can securely transmit CA code via a broadband channel. To design DCAS headend server, we define core functions to be performed in the headend and categorize them into four sections such as authentication, provisioning, personalization and key management. In order to verify the stability and effectiveness of the implemented headend servers, we construct a testbed using them and a legacy cable headend system in a laboratory. The experimental results show that the DCAS headend servers are well designed.
