Encryption algorithm used by DVB television standard
The Common Scrambling Algorithm (CSA) is the encryption algorithm used in the DVB digital television broadcasting for encrypting video streams.
CSA was specified by ETSI and adopted by the DVB consortium in May 1994. It is being succeeded by CSA3,[1] based on a combination of 128-bit AES and a confidential block cipher, XRC. However, CSA3 is not yet in any significant use, so CSA continues to be the dominant cipher for protecting DVB broadcasts.
