Cardsharing

( Share German card enable or common access cards, literally map ) When Cardsharing is a single decryption card into multiple receivers used in Pay- TV at the same time. This is in breach of contract in general and possibly illegal.

A modified receiver ( "Card Data") continuously distributes the decoder key over a network connection to one or more additional receivers, which also need to be modified. The network connection can take place over the Internet, so that the receiver does not have to be at the same location. Are all receivers in a household, it is called Home Sharing.

The modifications required are available especially for receivers with Linux operating system, partly as an extension or as an alternative firmware. The card distributed server must accompanied by a valid smart card be the unauthorized satellite receiver decoder receive the key via a LAN port and simulate the smart card via software. Although the decoder keys are exchanged in very short cycles of typically 7 seconds, it is possible to pass continuously with a conventional network connection and the appropriate hardware, this decoder key.

Card sharing can also be done as a so -called offline decoding. Here, the user takes an encrypted program as a transport stream to disk. Another person who has access to the smart card, logged at the same time, the key of this transmitter in a file. The user can later decrypt this file recording with suitable software (eg TSDEC ).

Cardsharing was used in 2005 to bypass the encryption of the pay- TV company Premiere.
