In this work it is shown how 128 bit SSE2 multimedia extension registers, present in Pentium IV class 32 bit processors, may be used to generate random numbers at several times greater speed then when regular general purpose registers are used. In particular, a 128 bit algorithm is presented for the Marsaglia MWC1616 generator from the DIEHARD battery of random number generator tests, and its p...

Chaotic systems have many interesting features such as sensitivity on initial condition and system parameter, ergodicity and mixing properties. In this paper, we exploit these interesting properties of chaotic systems to design a random bit generator, called CCCBG, in which two chaotic systems are cross-coupled with each other. To evaluate the randomness of the bit streams generated by the CCCB...

The nondeterministic property of the optoelectronic random bit generator (RBG) based on laser chaos are experimentally analyzed from two aspects of the central limit theorem and law of iterated logarithm. The random bits are extracted from an optical feedback chaotic laser diode using a multi-bit extraction technique in the electrical domain. Our experimental results demonstrate that the genera...

In the present paper the authors have introduced a new symmetric key cryptographic method called Bit Level Encryption Standard(BLES) which is based on bit exchanging or bit reshuffling method. The authors have introduced a completely new bit level encryption method. Nath et. al has already developed bit manipulation method called NJJSAA where the authors mainly used bit level right shift, bit l...

A random number generator generates fair coin flips by processing deterministically an arbitrary source of nonideal randomness. An optimal random number generator generates asymptotically fair coin flips from a stationary ergodic source at a rate of bits per source symbol equal to the entropy rate of the source. Since optimal noiseless data compression codes produce incompressible outputs, it i...

HMAC DRBG is a deterministic random bit generator using HMAC specified in NIST SP 800-90. The document claims that HMAC DRBG is a pseudorandom bit generator if HMAC is a pseudorandom function. However, no proof is given in the document. This article provides a security analysis of HMAC DRBG and confirms the claim.

A discrete random number (DRN) generator for stochastic differential equations is proposed. The generator has exactly 8 states and thus 10 DRN’s can be obtained from a single 32-bit random variable. This is advantageous when large numbers of DRN’s are needed, as for example in fluctuating latticeBoltzmann models. The moments of the discrete distribution match those of a Gaussian distribution (z...
