Verimatrix's Video Content Authority System for IPTV has been deployed to secure VOD premium content as part of TUS TELEKOM's IPTV offering.

Through the advanced application of Internet cryptography, including Public Key Infrastructure and X.509 digital certificates, VCAS offers much higher levels of content protection than traditional smartcard systems and automatically identifies security breaches. VCAS for IPTV is designed for two-way networks and has been integrated with Dreampark's middleware and Envivio's headend equipment for the TUS TELEKOM platform.

TUS TELEKOM is a telecommunications provider operating an ADSL network within Slovenian territory, offering the service on two networks; its own and on an incumbent network. Its IPTV service is a response to the growing demand for entertainment and is available initially on the TUS TELEKOM network.
