Abstract：Binary Sidel'nikov-Lempel-Cohn-Eastman sequences(or SLCE sequences) over have even Periods and almost perfect autocorrelation.However, the evaluation of the linear Complexity of these sequences is a challengingtask.In this paper, base on the study of S.Alaca and G. Millar (Cryptography andCommunications, pp.1-18,2016), the multiple roots of character polynomials of SLCEsequences is expressed into certain kinds of Jacobi sums. Then by making use ofGauss sums and Jacobi sums in the "semiprimitive" case, a new divisibilityresult for SLCE sequences is also derived..
