VCAS for Cable IPTV - Enabling Rich IPTV over Today’s Cable Networks
In the VCAS for Cable IPTV software-based content security solution, Verimatrix eliminates the vulnerabilities related to smart card-based architectures through the leverage of proven two-way Internet security protocols, a Public Key Infrastructure (PKI) public/private key pair system and X.509 digital certificates to ensure the integrity of all components in the broadcast chain. A downloadable security system for IPTV clients is not only more secure, it enables less expensive STB hardware and the renewable ViewRight STB security software can be updated as required.
The VCAS architecture implements a sophisticated model of key generation and management, coupled with offline encryption for on-demand video content and the best-of-breed AES and RC4 algorithms for real-time encryption of broadcast streams. All content is encrypted on a packet-by-packet basis and is maintained in an encrypted state throughout distribution and storage until the point of playback in authorized STBs, PCs and other client devices.
