On the Entropy of Oscillator-Based True Random Number Generators
True random number generators (TRNGs) are essential for cryptographic systems, and they are usually evaluated by the concept of entropy. In general, the entropy of a TRNG is estimated from its stochastic model, and reflected in the statistical results of the generated raw bits. Oscillator-based TRNGs are widely used in practical cryptographic systems due to its elegant structure, and its stocha...
متن کاملEntropy Evaluation for Oscillator-Based True Random Number Generators
True random number generators (TRNGs) are crucial to the implementations of cryptographic algorithms and protocols. The quality of randomness directly influences the security of cryptographic systems. Oscillator-based sampling is popular in the design of TRNGs due to its nice properties of elegant structure and high speed. However, the credibility of randomness generated from high-speed oscilla...
متن کاملSecurity Analysis of Pseudo-Random Number Generators
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 proposed in 2005 by Barak and Halevi (BH). This model involves an internal state that is refreshed with a (potentially biased) external random source, and a cryptographic function that outputs random num...
متن کاملRandom-number Generators Physical Random-number Generators
R andom numbers have applications in many areas: simulation, game-playing, cryptography, statistical sampling, evaluation of multiple integrals, particletransport calculations, and computations in statistical physics, to name a few. Since each application involves slightly different criteria for judging the “worthiness” of the random numbers generated, a variety of generators have been develope...
متن کاملThe Frequency Injection Attack on Ring-Oscillator-Based True Random Number Generators
We have devised a frequency injection attack which is able to destroy the source of entropy in ring-oscillator-based true random number generators (TRNGs). A TRNG will lock to frequencies injected into the power supply, eliminating the source of random jitter on which it relies. We are able to reduce the keyspace of a secure microcontroller based on a TRNG from 2 to 3300, and successfully attac...
