In this paper, a PN sequence generator is made using the features of one-dimensional chaotic schemes. The use of logistic map is done in a novel manner to generate a strong pseudo-noise sequence. The method, the logistic map scheme, is applicable for use on wireless networks because it requires simple procedures to generate the sequence. The method is shown to achieve reliability from the outlook of coding techniques, as well as unpredictability and randomness from the perspective of an eavesdropper. Lastly, the performance of the scheme is compared against that of existing techniques. Results from a comparative analysis indicate that the proposed method generally yields a greater number of reliable, unpredictable and random bits than existing techniques under the same conditions.
