Fully digital 1-D, 2-D and 3-D multiscroll chaos as hardware pseudo random number generators
2012
2012 IEEE 55th International Midwest Symposium on Circuits and Systems (MWSCAS)
This paper introduces the first fully digital implementation of 1-D, 2-D and 3-D multiscroll chaos using the sawtooth nonlinearity in a 3rd order ODE with the Euler approximation. Systems indicate chaotic behaviour through phase space boundedness and positive Lyapunov exponent. Low-significance bits form a PRNG and pass all tests in the NIST SP. 800-22 suite without post-processing. Real-time control of the number of scrolls allows distinct output streams with 2-D and 3-D multiscroll chaos
