A Cooperative Cellular and Broadcast Conditional Access System for Pay-TV Systems

Abstract

Abstract-The lack of interoperability between Pay-TV service providers and a horizontally integrated business transaction model have compromised the competition in the Pay-TV market. In addition, the lack of interactivity with customers has resulted in high churn rate and improper security measures have contributed into considerable business loss. These issues are the main cause of high operational costs and subscription fees in the Pay-TV systems. As a result, this paper presents the Mobile Conditional Access System (MICAS) as an end-to-end access control solution for Pay-TV systems. It incorporates the mobile and broadcasting systems and provides a platform whereby service providers can effectively interact with their customers, personalise their services and adopt appropriate security measurements. This would result in the decrease of operating expenses and increase of customers' satisfaction in the system. The paper provides an overview of state-of-the-art conditional access solutions followed by detailed description of design, reference model implementation and analysis of possible MICAS security architectures.

An efficient anonymous authentication protocol for mobile pay-TV

“…Many pay-TV systems can provide the services via wire, for instance, set-top-box (STB) with wire (Shirazi et al, 2010) or wireless communication, this paper propose the initialization phase using STB as a secure channel which usually is provided or assigned a STB ID by the pay-TV system providers for registration and payment. The following steps are performed to complete this phase:…”

Secure CAS‐based authentication scheme for mobile pay‐TV systems

“…With the popularization of handheld devices, such as smart phones and tablet personal computers, mobile broadcast pay‐television (TV) services have developed rapidly in recent years. To be able to ensure that only the authorized subscribers can access the services from the server, condition access systems (CASs) have been designed for use in pay‐TV systems . A typical model of CAS is composed of 2 parts, a head‐end system ( HS ) and a large number of receivers, such as mobile sets ( MS s).…”

[4][5][6] A typical model of CAS is composed of 2 parts, a head-end system (HS) and a large number of receivers, such as mobile sets (MSs). The structure of CAS also includes some important components, including the subscriber, encrypter, multiplexer, scrambler, and transmitter.…”

Simultaneous automated verification of conditional access system on multiple TV sets

“…In order to overcome the lack of interoperability between Pay-TV service providers and the lack of interactivity with customers, Shirazi, Cosmas and Cutts [2] presented the Mobile Conditional Access System (MICAS) as an end-to-end access control solution for Pay-TV systems. They aimed to lower operational costs and subscription fees in the Pay-TV systems which are the consequence of the mentioned lacks.…”
