A Method of Improving Qualities of True Random Sequences Based-On Wavelet Analysis

Abstract

With the higher demands for qualities of random sequences, true random sequences are paid more attention because of their higher security features. Although true random sequences have the character of unprediction, they still have problems on big deviation and correlation. The problem on how to get rid of these factors affecting security and obtain good randomicity is becoming the research focus. In this paper, the theory of wavelet analysis is applied to improve the qualities of true random sequences. The emulation results prove that the method used is effective in obtaining unpredictable and unrepeated random sequences.
