(a) Bifurcation diagram of EL map for to , with initial conditions of and ; (b)-(f) the iteration sequence diagrams of EL map for initial conditions of to , , and with an approximate spacing of . The whole interval does not produce chaotic behavior as elaborated in (d). Nonetheless, majority of this interval does exhibit as chaotic behavior; the iteration sequences are completely random and thus can be used in secure communication.
