Abstract: Disclosed herein is a key rotation scheme for a DRM system in a DASH-based media content service. A DASH encoder generates media decryption keys and provides a key list including the media decryption keys to a CP manager. Each media decryption key is identified by a key identifier (KID). The CP manager delivers the key list to a license server. The license server creates ECLs based on the key list, and delivers an ECL list including ECLs to the CP manager. Each ECL is identified by KID and includes an encrypted media decryption key and an encrypted KID. The CP manager generates a pssh box in which the ECL list is inserted into a data field, and delivers the pssh box to the DASH encoder. The DASH encoder delivers the pssh box to a client device, with the pssh box being included in a DASH MPD or media segment.

Abstract: A Renewable Conditional Access System (RCAS) headend of an RCAS and a method of transmitting messages between a Distributed Authorization Center (DAC) and a Conditional Access Module (CAM) Authentication module Sub-System (CASS) included in the RCAS headend. The method of transmitting messages between a DAC and a CASS includes: transmitting, by a CASS, a subscription message for a subscription request to a DAC when receiving a subscription request from a Set-Top Box (STB); processing, by the DAC, the subscription of the STB based on the subscription message received from the CASS; and transmitting, by the DAC, a response message including security parameters to the CASS.
