Secure IPTV

Internet Protocol Television (IPTV) refers to the digital distribution of television content over the Internet. It enables the streaming of media content – live TV shows, movies, and more – directly over IP networks. This is different from traditional methods of broadcasting television such as terrestrial, satellite, and cable formats.

Verimatrix Video Content Authority System provided digital video content security for City TV throughout its IPTV network. Last mile fibre networks in Moscow offered customers broadband Internet connectivity at up to 100 mb/s and are expected to reach more than 600,000 homes by the end of 2007. The new IPTV platform will provide its customers with a full range of pay-TV services, supported by network PVR functionality with stop, start and rewind of live TV. In addition subscribers will have access to compelling on-demand content, including Hollywood, independent and Russian feature films, as well as music, children's, and lifestyle programming. "City TV is a platform with many different pieces, including live broadcast, Video-on-Demand, time-shifted programs and rewind TV. We needed a flexible and proven security solution. Verimatrix's solution was the best we found that matched our requirements," said general director Sergey Plotnikov.

There are several ways in which IPTV services can be secured:

1. Encryption: This is one of the primary ways IPTV content is protected. Data encryption converts the content into code that can only be decoded and viewed by those who have the correct decryption key. Common encryption protocols used for IPTV include Secure Real-time Transport Protocol (SRTP) and Internet Protocol Security (IPSec).
2. Secure VPNs: Virtual Private Networks (VPNs) can be used to provide a secure tunnel for IPTV traffic. VPNs encrypt data being sent and received, protecting it from being intercepted or tampered with. This is particularly important when viewing IPTV content over public or untrusted networks.
3. Digital Rights Management (DRM): DRM systems control how IPTV content is used and distributed. They help prevent unauthorized copying or sharing of content. Examples of DRM systems used for IPTV include Google's Widevine, Apple's FairPlay, and Microsoft's PlayReady.
4. Conditional Access Systems (CAS): These are systems used to control access to IPTV content. They typically involve the use of smart cards or similar hardware, which contain decryption keys. Only authorized users who have the correct hardware can view the content.
5. Authentication and Authorization: These systems ensure that only authorized users can access the IPTV service. Authentication involves verifying the user's identity, typically through a username and password. Authorization involves confirming the user has the correct permissions to view the content.
6. Firewalls and Intrusion Detection Systems: These technologies can help protect IPTV systems from external threats. Firewalls restrict unauthorized access to the IPTV network, while intrusion detection systems monitor the network for signs of malicious activity.
7. Frequent Updates and Patches: Regular software updates and patches are crucial to keep IPTV systems secure. These updates fix known security vulnerabilities and help protect against the latest threats.
8. Secure Protocols for Payments: If the IPTV service is paid, it is important that the service provider uses secure protocols for payments, like SSL (Secure Sockets Layer), to protect users' financial information.

The security of IPTV is made possible through a combination of data encryption, secure networks, digital rights management systems, authentication and authorization procedures, and other security measures. These technologies help protect the content, the service providers, and the users from various potential threats.
