TLDR
A new pseudo-random bit generator is constructed that outputs n – c – 1 bits per exponentiation with a c-bit exponent and is among the fastest generators based on hard number-theoretic problems.
Short cycles in repeated exponentiation modulo a prime
TLDR
This work obtains nontrivial upper bounds on the number of fixed points and short cycles in the above dynamical system generated by repeated exponentiations modulo p.
Cycles in Repeated Exponentiation Modulo pn
TLDR
The number of cycles of the defined dynamical system generated by repeated exponentiations modulo a number is considered for $r=p^n$.
On the distribution of the power generator
TLDR
The uniform distribution of the RSA generator and the Blum-Blum-Shub generator is proved, provided that the period t > m 3/4+δ with fixed δ > 0 and, under the same condition, the uniform distributed of a positive proportion of the leftmost and rightmost bits.
Efficient Pseudorandom Generators Based on the DDH Assumption
TLDR
A family of pseudorandom generators based on the decisional Diffie-Hellman assumption is proposed, which can be based on any group of prime order provided that an additional requirement is met (i.e., there exists an efficiently computable function that enumerates the elements of the group).
Fixed Points for Discrete Logarithms
We establish a conjecture of Brizolis that for every prime p > 3 there is a primitive root g and an integer x in the interval [1,p − 1] with log g x = x. Here, log g is the discrete logarithm…
On the Security of Modular Exponentiation with Application to the Construction of Pseudorandom Generators
TLDR
It is shown that the output of the exponentiation modulo a composite function fN,g(x)=gx mod N (where N=P⋅ Q ) is pseudorandom, even when its input is restricted to being half the size (i.e. x< $\sqrt N$).
An Efficient Discrete Log Pseudo Random Generator
TLDR
It is shown that discrete exponentiation modulo a prime p can hide n − Ω(log n) bits and be used to discover the discrete log of g s mod p where s has Ω('log n') bits.
Concentration of points on curves in finite fields
We obtain analogues of several recent bounds on the number of solutions of polynomial congruences modulo a prime with variables in short intervals in the case of polynomial equations in high degree…
COUNTING FIXED POINTS, TWO-CYCLES, AND COLLISIONS OF THE DISCRETE EXPONENTIAL FUNCTION USING p-ADIC METHODS
TLDR
P-adic methods are used, primarily Hensel’s lemma and p-adic interpolation, to count fixed points, two-cycles, collisions, and solutions to related equations modulo powers of a prime p.
