> I wonder whether the academic publications are growing ever less relevant to practice. Or does the journal usually post such long articles directed at a general audience? limitations under the License. or "What's a seed?" Just to be clear: it's not a cryptography paper, is it? - Fast PRNG is almost a new field again: It's not crypto, but immensely useful. - PCG is not crypto, everybody should understand that. It is clearly not a journal paper and has a ton of extraneous content. Stone, Melissa E. O'Neill, and the student OCM team OOPSLA '11, (PDF, 2 pages). ), or acclaim him as a genius having produced fundamental, discontinuous advances in his field... or we can do both. Muphry's Law. We cannot analyze that, and it's not for cryptanalysts to review every single claim that comes across their desks. https://stackoverflow.com/questions/4720822/best-pseudo-rand... https://www.johndcook.com/blog/2017/08/14/testing-rngs-with-... https://v8project.blogspot.nl/2015/12/theres-mathrandom-and-... https://www.wired.com/2017/02/russians-engineer-brilliant-sl... https://ee.stanford.edu/event/seminar/ee380-computer-systems... http://www.pcg-random.org/posts/history-of-the-pcg-paper.htm... http://www.pcg-random.org/pdf/hmc-cs-2014-0905.pdf.

I feel bad for the poor NLP tokenizer that will process this later and decide that two-to-the-forty-seven is a word, strangely unattested in any corpora. It's not as though they rejected the paper on empirical grounds without a meritocratic review; they rejected it because they have a finite amount of time and (speaking as someone in the field) it's sort of annoying to read after page 10. She didn't have to write in this style to make it more accessible (and the relevant mathematics has a lower bound on how accessible it can be, anyway). distributed under the License is distributed on an "AS IS" BASIS, reproduce the same random sequence later, whereas if we want results that cannot Do the security analysis. Go implementation of Melissa O'Neill's excellent PCG pseudorandom number generator - MichaelTJones/pcg For a hidden variable theory, if Bell's conditions are correct, the results that agree with quantum mechanical theory appear to indicate superluminal effects, in contradiction to the principle of locality. The whole paper had that extra verbiage, everywhere. I think this is clearly true. > But I'll confess to not really understanding what all the fuss is about insecure generators.

The author writes "Meanwhile, at least one influential researcher (whose work I respect) had harsh words publicly for her result", and then quotes some of these words: In the linked test [2] by John D. Cook (who uses PactRand, a test similar to the (obsolete) DIEHARD), xorshift128+ and xoroshir0128+ fail within 3 seconds, while PCG ran 16 hours producing 2 TB of pseudo-random numbers without any suspicious p-value detected. On the latter, academic publication does indeed seem to be getting less relevant. This There was a story in the news the other week about people going around casinos predicting slot machines, so maybe this has already happened! The code does explain exactly what the issue is, i.e. > Bell's theorem states that any physical theory that incorporates local realism cannot reproduce all the predictions of quantum mechanical theory. parameters that set the initial state of the generator are usually known as the seed. Yes she did. Only if it turns out the work is actually good. But I think it's for more than simulation and rendering. The peer review process absolutely produces false negatives, but that doesn't really change the fact that this paper doesn't need to be nearly 60 pages, doesn't sufficiently analyze one of its central premises (6.2.2 Security Considerations) and in general focuses on treatise and levity rather than rigor. I found it interesting. Regardless of her attitude on academic accessibility, it is inappropriate for a paper introducing a novel primitive with proposed security considerations to spend the time explaining why determinism is a concern in functions dealing with randomness. This deterministic behavior is >Ding it for not analyzing her primitives but don't then call that security analysis. If you stripped out all the (weird, random) cryptographic stuff from this paper, it would read pretty much the same and make pretty much the same points, which tells me: it's not a cryptographic paper. WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. (There's an explanation of why in Knuth.) I was not referring to my observation of her own insufficient analysis as if it is a formal analysis on my part, I was observing (correctly) that she didn't do enough of her own formal analysis. I'll just quote it below. That she didn't get published for at best stylistic reasons means nothing.

Peer review which is a cornerstone to the academic/scientific community stumbled on style and didn't get to merit. The paper is 58 pages because, "think of the unwashed masses who can't understand our work! That is exactly what peer review should do, to determine whether the idea has merit. It's quite long and takes an eternity to reach this simple point. But the mere use of a 2 Or at least, I think it isn't?

however, with each adding at least some element of additional challenge. Authors introducing novel results with cryptographic considerations typically perform their own analysis and publish that in the paper with the result.

If I don't know these details very well, how can I properly assess the author's results? I do however, care about prediction difficulty, and I don’t like trivially predictable generators. generators, such as the Mersenne Twister [35], we have to go to a little more trouble and Given the PractRand results it makes sense, I guess, but I had read that Vigna's generators were supposed to pass TestU01. There are other ways to tell whether a piece of work is relevant, or credible. For more than 30 years, people used the following example to show the elegance of functional programming: People claimed that this code showed the Sieve of Eratosthenes; unfortunately however, it isn't that algorithm. If you repeatedly take three sequential values from one and treat them as 3D coordinates, the points line up in parallel planes. That she ran into a paper wall doesn't bother her because she's openly publishing is even better. She uses phrases like, "PCG is a middle ground between security and performance." We're already there with Inter-universal Teichmüller Theory (https://en.wikipedia.org/wiki/Inter-universal_Teichm%C3%BCll...), the entire mathematical field singlehandedly created by Mochizuki to prove the ABC Conjecture. are you joking? Describes a new permutation technique, founded on the idea of. Better PRNGs for simulation is definitely in its bailiwick. She purports to introduce a novel result that bridges "medium-grade" performance characteristics and security characteristics in one primitive. be easily reproduced, we should select the seed in some inscrutable (and, ideally, nondeterministic) way, and keep it secret. They are fast, easy to implement, and fairly space efficient. This paper could have been 10 pages. The paper itself[1] is extremely readable by the standards of most cryptography research. to L’Ecuyer’s excellent paper [25], and without reading it closely (who has time to You can always update your selection by clicking Cookie Preferences at the bottom of the page. Maybe some idiot write code for a gambling machine in C++ and use whatever PRNG is to hand.

"Consider the set P {p1, p2, ... pN} representing providers and the set C {c1, c2, ... cN} representing customers". Programmers using OCM simply write code as if they were using the cooperative multithreading model (CM) for uniprocessors. I think academia frequently gets lost in the ivory tower and loses touch with what an accessible paper looks like; this is not an answer to that, it's a swing in the other direction, where papers with truly novel results will suddenly be hundreds of pages and tens of pages of setup. I’ve learn it best never to say “cryptographic security” or “cryptographic properties” when trying to place something on a spectrum of prediction difficulty. If you're not going to sufficiently specify your claims, don't be surprised when the academic community ignores them (even if they're valid!). Learn more. Melissa Crystal O'Neil [citation needed] (born July 12, 1988) is a Canadian singer and actress. (Really!). Could you share the paper? In some sense I think this is a pity: as an academic-turned-practitioner I like academic-style publications. This would also have helped the career of the underlings. I appreciate her attitude on accessibility, which is in keeping with that institution's philosophy. Unfortunately, 204209821 is the

In still other ways, it's a good example of what we might see increasingly, which is a researcher having a lower threshold for the typical bullshit out there. ), meanwhile the thing is 58 pages because she takes the time to explain what "determinism" and "seeds" are to her audience. Do the security analysis. The author's tone in her writing is something I take issue with. If nothing happens, download the GitHub extension for Visual Studio and try again. It took me longer to get through this "accessible" paper than it did for me to get through any of Boneh's papers on constrained and puncturable pseudorandom functions! Mostly that won’t actually help though, because a cryptographer would say “Ha! The basic idea is that teachers also need to be applied psychologists, because our classrooms are a minefield of subtle influences. I'm not going to sit and read your 60 page paper that could have been compressed to 10 pages if you just got to the point and assumed your audience understood the field well enough to assess your results. the algorithm has iterated its state since that point. that I personally think would be really challenging to predict.
