Divisible E-Cash from Constrained Pseudo-Random Functions
E-Cash anonymity Constrained PRF
2019/2/26
Electronic cash (e-cash) is the digital analogue of regular cash which aims at preserving users' privacy. Following Chaum's seminal work, several new features were proposed for e-cash to address the p...
SoK: Security Models for Pseudo-Random Number Generators
Pseudo-random number generation security models entropy
2017/3/2
Randomness plays an important role in multiple applications in cryptography. It is required in fundamental tasks such as key generation, masking and hiding values, nonces and initialization vectors ge...
On a decentralized trustless pseudo-random number generation algorithm
public randomness collusion algorithm works w.h.p.
2016/3/2
We construct an algorithm that permits a large group of individuals
to reach consensus on a random number, without having to rely
on any third parties. The algorithm works with high probability if

Robust Pseudo-Random Number Generators with Input Secure Against Side-Channel Attacks
Randomness Entropy Side-Channel countermeasures
2016/1/27
A pseudo-random number generator (PRNG) is a deterministic algorithm that produces
numbers whose distribution is indistinguishable from uniform. In this paper, we extend the formal
model of PRNG wit...
An Efficient Pseudo-Random Generator with Applications to Public-Key Encryption and Constant-Round Multiparty Computation
constant-round cryptographic protocols multi-party computation pseudo-random generator
2016/1/26
We present a pseudo-random bit generator expanding a uniformly random bitstring
r of length k/2, where k is the security parameter, into a pseudo-random bit-string
of length 2k − log2
(k) usi...
On the Design of LIL Tests for (Pseudo) Random Generators and Some Experimental Results
foundations pseudorandomness
2016/1/26
Random numbers have been one of the most useful objects in statistics, computer science, cryptography, modeling, simulation, and other applications though it is very dicult to construct true randomne...
The Index j in RC4 is not Pseudo-random due to Non-existence of Finney Cycle
RC4 Non-randomness Pseudo-random Index
2015/12/22
In this very short note we prove that the pseudo-random index j of RC4 is indeed not
pseudo-random. This is a simple result that missed our attention for quite a long time. We
show that in long term...

Physical Pseudo Random Function Radio Frequency Sources Security
2015/6/25
There is tremendous market potential for location-based services (LBS), enabled by the rapid growth in the numbers of personal navigation devices and GPS-enabled mobile handsets. One of the major diff...
Security Analysis of Pseudo-Random Number Generators with Input: /dev/random is not Robust
Randomness Entropy
2014/3/12
A pseudo-random number generator (PRNG) is a deterministic algorithm that produces numbers whose distribution is indistinguishable from uniform. A formal security model for PRNGs with input was propos...
VMPC-R Cryptographically Secure Pseudo-Random Number Generator Alternative to RC4
stream cipher distinguishing attack
2014/3/6
We present a new Cryptographically Secure Pseudo-Random Number Generator. It uses permutations as its internal state, similarly to the RC4 stream cipher. We describe a statistical test which revealed ...
Experimental study on non-destructive testing of rock bolts based on pseudo-random signal
Pseudo-random signal Rock bolts Non-destructive testing Correlation analysis
2012/3/28
The quality of rock bolt anchoring is closely related to the stability and safety of underground engineering and slope protection. In this paper, non-destructive testing of rock bolts is proposed base...

The standard approach for constructing a large-stretch pseudo-randomgenerator given a one-way permutation or given a smallerstretch pseudo-randomgenerator involves repeatedly composing the given primi...
How strong is Nisan’s pseudo-random generator
Computational complexity Space bounded Derandomization
2012/11/30
We study the resilience of the classical pseudo-random generator (PRG) of Nisan (1992) [6] against space-bounded machines that make multiple passes over the input. Nisan’s PRG is known to fool log-spa...

Internet Security Chaotic Sequences Statistical Tests
2010/12/28
In this paper, a new chaotic pseudo-random number gen-erator (PRNG) is proposed. It combines the well-known ISAAC and XORshift generators with chaotic iterations. This PRNG possesses im-

2010/12/8
We study the resilience of random and pseudorandom directed graphs with respect to the property of having long directed cycles. For every 0 < < 1/2 we find a constant c = c(
) such that the followin...
