BISS E

BISS E is a more secure version of BISS Mode 1. In this mode the CSW is
encrypted to prevent clear keys from being used to access encrypted content.
The Encrypted CSW is also referred to as the ESW (Encrypted session word).
There are four additional BISS Modes to handle an ESW. These are:
•
•
•
•
3.11.3.5.3

BISS E Fixed / BISS E Ericsson

These modes of operation are used to provide a secure content link from one
encoder to one receiver. The ESW in both of these cases is encrypted using the
internal fixed serial number of the receiver. As such this method cannot be used to
send content to more than one receiver.
A series of ESWs (one for each receiver can however be generated such that the
CSW can be decrypted for each unit e.g.
•
•
•
Next,

The receivers will then decode the ESW using its own unique serial number
