Counting functions for 2 n-periodic binary sequences with 4-error linear complexity
摘要
Abstract
The k-error linear complexity is one of the important measures for assessing the stability of sequence cipher. First, we presented the process of counting functions of 2n-periodic binary sequences with given 4-error linear complexity. Then we studied the critical error linear complexity via cube theory and sieve method. The possible values of the 4-error linear complexity of corresponding critical error point (descent point) were obtained and the number of sequences with given 4-error linear complexity of corresponding critical error point were es-tablished. Finally, we got the all the possible value forms of the 4-error linear complexity and the counting func-tions of 2n-periodic binary sequences.关键词
