Irdeto

Irdeto refers to a type of encryption system which is primarily offered by a company known by the same name. This encryption system is used in satellite broadcasting systems. Broadcasting companies that incorporate the Irdeto system include those in countries such as South Africa and Australia.

Irdeto services cover a wide set of technologies. This encryption system provides digital content protection in mobile services, Internet Protocol Television (IPTV), and digital television.

To perform encryption, Irdeto uses a conditional access system. This system enables legitimate subscribers to properly view the content they want. At the same time, the conditional access system of Irdeto prevents unauthorized individuals from viewing certain content. The latter is achieved by using a specific device which provides a set of secret keys. These secret keys scramble the signals, making them unreadable for devices that are not allowed to have access to the content.

Irdeto is available in two major packages:

  1. M-Crypt is intended for small and medium-sized digital broadcasting systems.
  2. PIsys is intended for digital broadcasting systems that offer numerous channels and those that have a much larger clientele.

The first version of Irdeto was used for a certain period of time; however, broadcasters noticed a set of vulnerabilities within the encryption system. These vulnerabilities enabled experienced users to pass through the digital protection service and illegally access content. Consequently, the developers of Irdeto revised the system and created Irdeto 2. This revision provides a higher security level and better technologies to detect unauthorized access.
