Abstract

The maximal length pseudo random binary sequence is known as m-sequence. The m-sequence of domain {0, 1} can be represented in bipolar form of sequence in domain {-1, 1}. The m-sequences are used for watermarking because of their very good correlation properties, noise like characteristics and resistance to interference. This paper investigates a new locking condition in the operations of an m-sequence generator. Through this finding it is revealed that an LFSR structure may turn into locking state due to particular seed selection other than the all zeros or all ones.
