Predictive Models for Min-entropy Estimation

Random numbers are essential for cryptography. In most real-world systems, these values come from a cryptographic pseudorandom number generator (PRNG), which in turn is seeded by an entropy source. The security of the entire cryptographic system then relies on the accuracy of the claimed amount of entropy provided by the source. If the entropy source provides less unpredictability than is expec...

Minimizing false negative and false positive errors on entropy health tests

this paper gives an alternative model of continuous health tests that allows us to drastically reduce the error rates; that is, it allows us to better detect when a noise source has degraded to the point where it imperils security, while at the same time reducing the number of false alarms. The current NIST SP 800-90B draft proposes a model for an entropy source. In this model, there is a noise...

In this paper, we derive rst some results on the Shannon entropyin order statistics and their concomitants arising from a sequence of f(Xi; Yi): i = 1; 2; :::g independent and identically distributed (iid) random variablesfrom the bivariate normal distribution and extend our results to a collectionC(X; Y ) = f(Xr1:n; Y[r1:n]); (Xr2:n; Y[r2:n]); :::; (Xrk:n; Y[rk:n])g of order sta-tistics and th...

Entropy generation analysis of non-newtonian fluid in rotational flow

The entropy generation analysis of non-Newtonian fluid in rotational flow between two concentric cylinders is examined when the outer cylinder is fixed and the inner cylinder is revolved with a constant angular speed. The viscosity of non-Newtonian fluid is considered at the same time interdependent on temperature and shear rate. The Nahme law and Carreau equation are used to modeling dependenc...
