About DVB-CSA - Security Algorithm

Encryption is an essential part of a technology because it ensures the effective and secure authentication of users. A security algorithm is a mathematical procedure used to encrypt data. Information is encoded and requires the use of a software key to transform the data back into its original form.

As Custodian, Sisvel is responsible for the licensing of the DVB-CSA2 and DVB-CSA3 algorithms, and the distribution of the specifications for the Common Descrambling Systems and Scrambling Technologies which together make up each algorithm. Furthermore, other confidential information typically concerning IP rights may also be necessary.

  • Irdeto

  • Nagravision *

  • Synamedia

  • Viaccess-Orca

* For DVB-CSA3 only.
