Welcome to another wonderful week. I hope you all had a great weekend. Often times you might have been hearing different names that are associated with your satellite tv/PayTV packages. These names are not actually the name of your satellite tv provider. They are the name tag on your Smartcard/Viewing card. For instance, Multichoice Africa, owner of DStv and GOtv carries the name “Irdeto” on its smartcard. I am going to talk about Top Satellite signal encrypting companies today. Not only that, I shall be giving a run through of their history, mode of operation and their major clients.
It is noteworthy that most of these Top Satellite signal encrypting companies don’t involve in just satellite TV encryption only as 90% of them are also involved in other forms of security. For instance, Irdeto encrypts every digital content including games.
Satellite TV/Pay-TV providers encrypt their channels in other to prevent unauthorized viewing of their contents. Often times, the company that is responsible for securing their contents is separated from the department that creates the contents. Security is serious business. We are going to look into those conditional access security companies and their mode of operation.

Top Satellite signal encrypting companies: I compiled this list in no particular order
PowerVu sure makes it to our list of Top Satellite signal encrypting companies as a conditional access system for digital television. PowerVu is developed by Scientific Atlanta.
PowerVu encrypting is used for professional broadcasting, notably by Retevision, Bloomberg Television, Discovery Channel, AFRTS and American Forces Network. It is also used by cable companies to prevent viewing by unauthorized viewers.
PowerVu has decoders that decode signals from certain satellites for cable distribution services. These decoders can also be used just like the FTA (Free-To-Air) satellite receivers if properly configured. PowerVu is considered very secure and although it has been compromised, it uses a complicated system to authorize each PowerVu receiver and trace its history of ownership and usage. Most PowerVu users are professional cable or satellite companies, using the service and equipment for signal redistribution because regular users cannot afford it. In addition, powerVu use a form of satellite key sharing as it requires no internet.
Top Satellite signal encrypting companies: Irdeto 1 & 2

Irdeto is another feature on our top Satellite signal encrypting companies. This is an originally Dutch company that makes software for securing Pay TV. The regional head offices are located in Hoofddorp, Beijing and San Francisco. They produce smartcards and surface mounted devices required for visualization of pay TV via cable, satellite, IPTV and mobile phones.
According to Wikipedia: Irdeto was founded in 1969 by media engineer Pieter den Toonder in Dordrecht. Irdeto is an amalgamation of I ngenior r De n To under. The company is now a subsidiary of the South African media group Naspers.
Several providers around the world use the system, as in the Netherlands almost all cable companies (with the exception of UPC, which used Nagravision ). Satellite provider CanalDigitaal also used this encryption until December 10, 2012.
The original encryption system Irdeto 1 became vulnerable to piracy in the late 1990s; Illegal smart cards appeared with which one could receive the encrypted channels for free. An improved version was introduced in October 2000 under the name Irdeto 2 . This coding was restricted in 2007. With the so-called Gammakaart you could and can take a free look at the packages of Ziggo and until December 10, 2012, also Canal Digital. The map is now difficult to get hold of by measures against piracy.
Top Satellite signal encrypting companies: Viaccess
Viaccess is an encrypting system for digital television developed by France Télécom. There are four versions in use today, Viaccess PC2.3, Viaccess PC2.4, Viaccess PC2.5 and Viaccess PC2.6.
Viaccess was developed as the digital version of the EuroCrypt system used with the hybrid MAC system.
The first version is sometimes referred to as Viaccess 1, and the latter three, although different, as Viaccess 2. PC2.3 and PC2.4 are known to be ineffective, and many set-top boxes can be ‘patched’ to decrypt Viaccess signals without payment. however, PC2.5 and PC2.6 are secure, with PC2.5 remaining secure two years after its first commercial deployment. PC2.6 was introduced at the end of 2005.
There are two modifications of Viaccess PC2.3 in use. The first, known as TPS Crypt, is used by TPS. Despite being compromised also, the TPS Crypt system has been further modified to utilise Advanced Encryption System (AES) keys. These AES keys were originally updated once daily. However after this inconvenienced unauthorised viewers little, a second TPS crypt system was introduced, by which keys are changed every 15-20 minutes, with keys being sent over TPS’s internal Open TV system. This, therefore, meant that only TPS receivers could receive the new AES key and not the insecure TPS subscription cards. Monitoring and analysing the keys by hacking groups, however, has brought about key lists, where the AES keys have been successfully predicted. Implementation of this procedure of automatically updating keys has proved difficult, if not impossible, to implement on many satellite receivers, rendering the TPS Crypt AES system a general success.
The second Viaccess modification, called ThalesCrypt, is used by Canal Satellite France to protect its contents on the transport network to the head-ends of the cable networks; it is an over-encryption mechanism of the original protocol encryption keys.
Viaccess is currently used by a large number of providers. These include;
* TPS* ART
* Televisa Networks
* Canal Satellite France and canal Afrique
Also, Viaccess is the 3rd largest conditional access system provider in the world (in 2004). In addition, Viaccess is also a subsidiary of France Télécom which offers pay TV and DRM enabled software.
