司期为2^n的线性复杂度为2^n-9二元序列的k错线性复杂度分布
K-error linear complexity distribution of 2n-periodic binary sequences with linear complexity 2n--9
摘要
Abstract
The linear complexity and the k-error linear complexity of a sequence have been used as important measures of key stream sequence strength and stability. By studying linear complexity of binary sequences with period 2n, it is proposed that the computation of k-error linear complexity should be converted to finding error sequences with minimal Hamming weight. Based on Games-Chan algorithm,4-error linear complexity distribution of 2^n-periodic binary sequences with linear complexity 2^n-9 is discussed, and the complete counting functions on the 4-error linear complexity of 2^n-periodic binary sequences with linear complexity 2^n-9 are presented.关键词
