“…Moon, Kim, Park, Paik and Park [1] suggest that IPTV systems adopting one of conditional access systems provided by a specific major vendor have a difficulty in changing the conditional access system loaded on a set-top box or on a removable hardware device, such as Smart card. They propose a dynamic conditional access system for an IPTV set-top box that securely downloads cryptographic software and dynamically executes the cryptographic software when it is required.…”

Conditional access system (CAS) is an essential part of Pay-TV systems, used to restrict access to certain content only to the users who subscribed to that content. Therefore it is useful to have automated verification of CAS system in integrated digital TV sets which contain the conditional access module. This paper presents a novel system for automated verification of CAS in multiple TV sets. The system supports simultaneous verification of 16 integrated digital TV sets produced by different manufacturers. The verification algorithm incorporates pop-up detection and optical character recognition in order to detect when each TV set sends the CAS message. Comparison with the reference image representing the expected response makes decision on the correctness of CAS functionality in the TV set. The system brings speed gain greater than 10 compared to the system which verifies one TV set at a time.

“…Through the two functions, CAS can greatly ensure that only authorized client can access to the network and obtain the right data. Traditional CAS is a 2-layer system and is widely used in information sharing network like broadcasting TV [5], IPTV [6] etc. But it is obvious that the 2-layer CAS cannot match well the 3-layer IISN on the architecture.…”

Immeasurable information sharing network (IISN) has been proposed for improving information sharing service in remote rural. How to ensure information security becomes a very important issue for the new network. In this paper, we propose a new conditional access system (CAS) model and a key management scheme for IISN. In the model, we place emphasis on making the CAS more suitable for IISN; we change the traditional two-layer CAS to three-layer CAS based on the architecture of IISN. Besides, we propose a novel 4-level key management scheme for our CAS model. Performance analysis shows that our proposed scheme is highly secure and has outperformance on key management cost.
