  • Generator of chaotic sequences and corresponding generating system
    Patent number: 8781116
    Abstract: A generator of chaotic sequences of integer values is provided. The generator includes at least two discrete recursive filters at least of first-order, generating an output chaotic sequence of integer values, each recursive filter comprising means for implementing a nonlinear function connected via an exclusive-or gate to means for generating a perturbation sequence of integer values. The two filters are mounted in parallel. The chaotic sequence output from the generator is equal to an exclusive-or of the chaotic sequences output from the recursive filters, and in the means for implementing the nonlinear function includes a chaotic map.
