摘要
本文给出了一个测量流密码序列稳定性的重要指标k- 错线性复杂度的算法,即求GF(q)上(q= pm ,P:素数)周期为N= pn 序列的k- 错线性复杂度的快速算法。在这里对广义Gam es-Chan 算法——GF(q)上pn 序列线性复杂度算法进行了简化,并给出了GF(q)上pn 序列k- 错线性复杂度算法及其证明。
An algorithm for k error linear complexity of sequences over GF(q)(q=p n,p a prime)with period p n,is given in this paper The k error linear complexity is an index for measuring the stability of the sequences The algorithm is derived by the generalized Games Chan algorithm over GF(q) with period p n The generalized Gamse Chan algorithm is simplifed in the paper,and a proof of the algorithm is also given
