Abstract: PURPOSE: A downloadable conditional access system server, a digital multimedia broadcasting terminal, and a method for providing downloadable conditional access system service are provided to offer a DCAS solution using a DMB net and a mobile radio communication network. CONSTITUTION: A message transfer part(311) transmits a DCAS message including the DCAS information through a first data channel to a DMB terminal. An image transmitting portion(312) transmits the common conditional access client image through a second data channel to the DMB terminal. The DMB terminal requests the personalization information related through a mobile communication channel to the operation of the common conditional access client image. An information transfer part(313) processes the authentication about the DMB terminal. The information transfer part transmits the personalization information through the mobile communication channel to the DMB terminal.
