Abstract

A condition access system (CAS) refers to a hardware-based system that allows only authenticated users to have access to contents. The CAS has many disadvantages found in that in the replacement of multiple service operator (MSO) a set-top box should be also changed and the smart-card often causes malfunction. To deal with the problems, exchangeable CAS (XCAS) was developed in 2009. However, in the XCAS, no method to authenticate a proper set-top box has been put forward. In this paper, we propose a novel program for set-top authentication in the XCAS. Additionally, we offer a format of certificate of authentication, and procedures of issuing the certificate for broadcasting services suitable for the XCAS. The technical method of authentication a set-top box that will be discussed is of high efficiency since in the MSO it requires only two subjects to communicate during the authentication in the MSO.
