Abstract
The generator comprises three subassemblies, each comprising an adder and registers, said three subassemblies making it possible to provide three recursive sequences. Each sequence is dependent on variables constituted by initialization bytes. One state of the generator is defined by a particular combination of three sequences and each state determines an output variable, which is the desired coding or decoding byte.
