What is card sharing in set top box?

What is card sharing in set top box?

Card sharing sends the decryption codes (code words) from the smart card in the receiver of a legitimate pay TV subscriber to an illegal server on the Internet. Using a modified set-top box (receiver), non-paying users acquire the codes from the server.

What is smart card sharing?

The security of conditional access smart card technology is limited by the security of the DVB standard in which it operates. With card sharing, however, the smart card and its security features are bypassed; software intercepts the decrypted control word and allows the user to share it across a computer network.

How do smart card readers work?

The contactless smart card contains an antenna embedded within the plastic body of the card (or within a key fob, watch or other document). When the card is brought into the electromagnetic field of the reader, the chip in the card is powered on.

What is smart card advantages and disadvantages?

Advantages of smart cards are that they provide enhanced security for private data, can hold different types of data and keep valuable data safe from deletion or theft. Disadvantages are that they are more expensive due to their complexity and are only compatible with certain smart card readers.

How secure are smart cards?
