Özet

Discrete time chaos based true random number generators are lightweight cryptographic primitives that offer scalable performance for the emerging low power mobile applications. In this work, a novel design method for discrete time chaos based true random number generators is developed using skew tent map as a case study. Optimum parameter values yielding maximum randomness are calculated using a mathematical model of true random number generator. A practical information measure is used to determine the maximum allowable parameter variation limits. Appropriate mapping between dynamic system and circuit parameters is established and a current mode skew tent map circuit is designed to validate proposed method. © 2013 Elsevier B.V.
