Abstract
NOR self-decimated sequences are attractive for stream ciphers because they have a good statistical property and the hardware construction is Very sim ple. This paper presents an analysis of NOR self-decimation system for any parameter. We first determine the period. Then we show the exact distributi on of consecutive two bits and three bits, which are shown to be almost uni form distribution.
