it cycles through all possible 2n1 states within the shift register except the state where all bits are zero), unless it contains all zeros, in which case it will never change. Neither scheme should be confused with encryption or encipherment; scrambling and spreading with LFSRs do not protect the information from eavesdropping. Three general methods are employed to reduce this problem in LFSR-based stream ciphers:. The sequence of numbers generated by an LFSR or its XNOR counterpart can be considered a binary numeral system just as valid as Gray code or the natural binary code. LFSRs are also used in radio jamming systems to generate pseudo-random noise to raise the noise floor of a target communication system. In this case, the exclusive-or component is generalized to addition modulo-q (note that XOR is addition modulo 2), and the feedback bit (output bit) is multiplied (modulo-q) by a q-ary value, which is constant for each specific tap point. Retrieved 11 October 2011. When the LFSR runs considerably faster than the symbol stream, the LFSR-generated bit sequence is called chipping code.
