Irdeto Creates Conditional Access System for Mobile Devices

SK Telecom, a leading Korean telecommunications operator, is using a conditional access system (CAS) from Irdeto Access to deliver encrypted content to mobile phones, PDAs, and in-vehicle devices. The system uses Dual Key Hierarchy Protection, a technique that Irdeto claims significantly reduces CA-related bandwidth consumption while providing scalability beyond 10 million subscribers. Additionally, Irdeto Access' Rapid Refresh technique provides additional layers of countermeasures in the event of against piracy. The mobile solution is based on Irdeto's existing DVB conditional access system for large-scale satellite DTH, cable, IPTV, and terrestrial broadcasting networks.
