| Abstract: | Linear complexity and k-error linear complexity of periodic sequences are important security indices of stream cipher systems.For the 2 n-periodic binary sequences with linear complexity 2 n,the distribution of the 3-error linear complexity of the specific periodic sequences is researched,and the upper and lower bounds of the expected value of the 3-error linear complexity of the specific periodic sequences are established. |
| Keywords: | linear complexity k-error linear complexity expectation bound |
