The design and application of bank authenticator device with a novel chaos based random number generator

In the literature reviews, it has been generally seen that integer operations are used to generate bit sequences in random number generation(RNG) algorithms. Different from the literature, in this study, an encryption device has been developed that uses the algorithm of generating random numbers by using the sensitive digits of floating-point numbers. The developed encryption device has been based on a non equilibrium point chaotic oscillator that makes impossible for Shilnikov decoding analysis. Developed encryption device has successfully passed the statistical NIST-800-22 randomness test which is the highest international standard. The encryption performance of the developed device has been realized through an exemplary banking system interface application. The obtained results show that developed device can be used as a high security authentication tool in Internet banking sector and remote terminal units of automation systems.
