Basic Interoperable Scrambling System, (BISS) Prior to its development, "ad hoc" or "occasional use" satellite news feeds were transmitted either using proprietary encryption methods (e.g. RAS, or PowerVu), or without any encryption. Unencrypted satellite feeds allowed anyone with the correct equipment to view the program material. Proprietary encryption methods were determined by encoder manufacturers, and placed major compatibility limitations on the type of satellite receiver (IRD) that could be used for each feed.

Biss Keys- simple coding, channels it can be opened using the receiver with a built-in emulator coding. The key length is equal to sixteen digits of the hexadecimal number system.

BISS was an attempt to create an "open platform" encryption system, which could be used across a range of manufacturers equipment. There are mainly two different types of BISS encryption used: BISS-1 transmissions are protected by a 12 digit hexadecimal "session key" that is agreed by the transmitting and receiving parties prior to transmission. The key is entered into both the encoder and decoder, this key then forms part of the encryption of the digital TV signal and any receiver with BISS-support with the correct key will decrypt the signal. BISS-E (E for encrypted) is an variation where the decoder has stored one secret BISS-key entered by for example a rightsholder.

New biss key

This is unknown to the user of the decoder. The user is then sent a 16-digit hexadecimal code, which is entered as a "session key". This session key is then mathematically combined internally to calculate a BISS-1 key that can decrypt the signal. Only a decoder with the correct secret BISS-key will be able to decrypt a BISS-E feed. This gives rightsholder control as to exactly which decoder can be used to decrypt/decode a specific feed. Any BISS-E encrypted feed will have a corresponding BISS-1 key that will unlock it. BISS-E is amongst others used by EBU to protect UEFA Champions League and other high profile satellite feeds.
