Implementation of a Stream Cipher Based on Bernoulli's Map
Ricardo Francisco Martínez-González, José Alejandro Díaz-Méndez · International Journal of Computer Science and Information Technology · 2014
A stream cipher was implemented on a FPGA.The keystream, for some authors the most important element, was developed using an algorithm based on Bernoulli's chaotic map.When dynamic systems are digitally implemented, a normal degradation appears and disturbs their behavior; for such reason, a mechanism was needed.The proposed mechanism gives a solution for degradation issue and its implementation is not complicated.Finally, the implemented cipher includes 8 stages and 2 pseudo-random number generators (PRNG), such cipher was tested using NIST testes.Once its designing stage, it was implemented using a developing FPGA board.
