Según la Wikipedia:

Three versions of Nagravision are in common use for digital satellite television, known as Nagravision, Nagravision Cardmagedon, and Nagravision Aladin. Nagravision Cardmagedon and Aladin are often confused with each other. Nagravision Cardmagedon is however, a complicated combination of Nagravision Aladin and Mediaguard SECA 2 encryption.

The decryption unit is either integrated into a receiver, available as a conditional access module (CAM), or as one of many encryption schemes supported on a CAM emulator.

Nagravision has been adopted all over the world as a conditional access system, with providers like Virgin Media UK and Dream Satellite TV Philippines (on Nagravision 1), Polsat of Poland, Digital+ Spain, TV Cabo Portugal, Premiere Germany, Digi TV Romania, BellExpressVu Canada and Dish Network USA (On Nagravision A).

Digital+ is the only provider using Nagravision Cardmagedon (and also Nagravision Aladin) after its adoption in March 2005.

The original Nagravision 1 is now almost obsolete after it was originally compromised in 1999, although Dream Satellite maintain relative security by changing keys several times throughout the day, causing great inconvenience to unauthorized viewers.

The Nagravision Aladin providers have been confronting the issue of satellite signal piracy and smart card piracy, since the system was publicly compromised in summer 2005. At first, security of the system was regained, with software revisions, manipulation of the Nagravision encryption algorithm, along with the phasing out of older cards, like the ROM101 (and ROM102 in Europe) in favour of the newer ROM130.

Card hackers have, however, continued to compromise the encryption system, with continued software and key releases being made available to the public. Software emulation of the Nagravision system has been implemented in many Free-To-Air Satellite receivers, allowing unauthorised viewing to those who do not own an official card.
