Does min-entropy quantify the randomness of a sequence for academic writing

The past outputs of the system generated prior to the break-in, should still be indistinguishable from random to the adversary naturally, this means the past states should not be reconstructable. It is the length of the shortest program generating your file.

See also Shannon—Hartley theorem. Immunity to adversarial entropy: While a PRG can be used to expand a short random sequence into a longer sequence, there are still considerable security vulnerabilities for real PRG systems. The objective of the hider is to survive as many rounds as possible, while the objective of the seeker is to catch a mouse as early as possible, ending the game.

So we've already made the assumption of working with a particular statistical test, because we can't answer the question otherwise. A New Type of Entropy Source Knowing that humans posses the capacity to generate randomness at least to some extent when they are playing some games, we can predict how random they will be.

Following the next "refresh" after the break-inall outputs should be indistinguishable from random to that adversary. For convenience, I'll use the positive value in the remainder of this answer.

For the purposes of randomness extraction, especially for cryptography, a more important measure is the min-entropy, the measure the probability of guessing the source, that is, the most common value.

Nonetheless, such asymmetric entropy measure might also be beneficial in cognitive domains. Our results suggest that humans can adjust both complexity and regularity in different movement types and contexts and that this can be assessed with information-theoretic measures of the symbolic sequences generated from movement trajectories.

In other terms, those sequences which actually present the modal number of alternations expected by chance are not perceived as maximally random because they contain too long runs of the same element.

Modeling the Overalternating Bias with an Asymmetric Entropy Measure

An alternative approach to defining "randomness", called Kolmogorov complexityis based on the data itself, regardless of how it was generated. I'm saying you don't need true random seeds, you just need unpredictable uncorrelated seeds.

The third system is direct gathering. The game matching pennies has two drawbacks. Randomness and induction from streaks: The issue of obtaining good randomness is not one of "send and forget.

The use, distribution or reproduction in other forums is permitted, provided the original author s or licensor are credited and that the original publication in this journal is cited, in accordance with accepted academic practice. Thus unadorned, the hide-and-seek game does not seem to be much more entertaining than matching pennies.

In particular, people consistently show the overalternating bias: Yet, intuitively, we feel that such a sequence is not very complex and in fact rather simple to generate. Randomness - Wikipedia defines it as: > Randomness is the lack of pattern or predictability in events.[1] A random sequence of events, symbols or steps has no order and does not follow an intelligible pattern or.

Kolmogorov complexity is a theoretical generalization of this idea that allows the consideration of the information content of a sequence independent of any particular probability model; it considers the shortest program for a universal computer that outputs the sequence.

A code that achieves the entropy rate of a sequence for a given model, plus the codebook (i.e. the probabilistic model), is one such.

However some stream ciphers are known to have "slow start" issues where initial output statistics show charecteristics that can aid an attacker especialy when part of the "key" or "plaintext" is known or easily guessable to an attacker (which has happened with both network encryption and.

The importance of obtai ning and using highly unpredictable keys is not just an academic question. There the notion of true randomness is hard to define and quantify.

Estimating the entropy rate or measuring the true randomness of an entropy source is difficult. For.
