Abstract—In this paper, a novel true random bit generator

(TRBG) based on a double-scroll attractor is proposed. The

double-scroll attractor is obtained from a simple model which

is qualitatively similar to Chua’s circuit. In order to face the

challenge of using the proposed TRBG in cryptography, the

proposed TRBG is subjected to statistical tests which are the

well-known Federal Information Processing Standards-140–1

and Diehard test suite in the area of cryptography. The proposed

TRBG successfully passes all these tests and can be implemented

in integrated circuits.
