Abstract
The algorithm COTA, a method for the study of the unpredictability of some running keys, is described. COTA can be applied to the case of binary sequences generated by a linear feedback shift register to whose stages a nonlinear function is applied. The results obtained with COTA are valid for any monlinear function with a unique term of a specific maximum order K. applied to any linear feedback shift registrer of a specific length L.
