Summary:
IP-TV utilizes Conditional Access System (CAS), which controls the subscriber access to content. Although the current CAS scheme provides access control via subscriber authentication, there is no authentication scheme for the content provided by service providers. Thus, there is a vulnerability of security, through which an adversary can forge content between the service provider and subscribers. In this paper, beased on a hash tree shceme, we proposed a efficient and strong source authentication protocol which removes the vulnerability of the current CAS.
