It is shown that the amount of true randomness produced by the recently introduced Galois and Fibonacci ring oscillators can be evaluated experimentally by restarting the oscillators from the same initial conditions and by examining the time evolution of the standard deviation of the oscillating signals. The restart approach is also applied to classical(More)
In their paper " A Provably Secure True Random Number Generator with Built-in Tolerance to Active Attacks " , B. Sunar, W. Mar-tin, and D. Stinson propose a design for a true random number generator. Using SPICE simulation we study the behaviour of their random number generator and show that practical implementations result in a too high frequency signal to(More)
