Key (Session Word)
Control word used for scrambling or descrambling
In BISS Mode E the key (Session Word) is protected by encrypting it using a key ID. An
encrypted key is generated by selecting DCB CSA BISS-E as key type, and using the Encode
mode, and supplying the key ID and key. The resulting encrypted key is displayed to the user in
a popup when the key is added, but is not available to the user later in time. The same
procedure is used in order to retrieve a clear key from an encrypted key and key ID by selecting
the Decode mode.
