Abstract The problem of finite precision degrades the cyptologic and statistical properties of chaotic maps, and sequences generated from maps conjugated with Tent map can be reconstructed precisely by short-sequence-prediction. This paper discusses topological conjugation of chaotic maps and its properties, derives the conjugate relation between Tent, logistic and 2nd-order Chebyshev maps. A method is given to produce chaotic sequences which can sustain this predictive attack.
