Cross-correlation of some extended d-form sequences

摘要

In this paper, we investigate the correlation property of extended d-form sequences for application in stream ciphers and pseudo-random number generators. Firstly, we present the cross-correlation of some extended d-form sequences, which is a generalization of Fu Chun-sheng's result. Based on this result, a method to form extended d-form sequences with ideal autocorrelation is obtained consequently.
