A scrambler (or randomizer) can be either: An algorithm that converts an input string into a seemingly random output string of the same length (e.g., by pseudo-randomly selecting bits to invert), thus avoiding long sequences of bits of the same value; in this context, a randomizer is also referred to as a scrambler.
The most common of these was a channel-based filter that would effectively stop the channel being received by those who had not subscribed. These filters would be added or removed according to the subscription. As the number of television channels on these cable networks grew, the filter-based approach became increasingly impractical.

A descrambler is a device that unscrambles the encoded signal and restores the picture and sound of a scrambled channel. Typical modern cable boxes include some form of descrambling ability.

However, as all operations are on 8-bit subblocks, the algorithm can be implemented using regular SIMD, or a form of “byteslicing”. As most SIMD instruction sets, (with the exception of AVX2 ) do not support parallel look-up tables, the S-box lookups are done in a non-bytesliced implementation, but their integration into the rest of the ...
