Jeb*ga, nimajo SloTek strokovnjakov.

Uporablja se PRNG algoritme, ki (še) niso bili uspešno napadeni. Kaj več si lahko prebereš kar od avtorja dveh bolj zanesljivih, kar jih poznamo: https://www.schneier.com/academic/fortu...

Kjer je potrebna boljša varnost (bančništvo, določene državne institucije, kdor koli varnost jemlje resno) se uporabljajo strojni generatorji TRNG, pogosto kar v HSM napravah. Čudno, mar ne?

Torej, Slo-Tech "strokovnjaki" so izjemni strokovnjaki zato, ker znajo brati angleško dokumentacijo. Sicer je ne razumejo, niti je ne znajo kritično ovrednotiti, ampak to ni tako pomembno. Če v PHP dokumentaciji piše cryptographically secure, potem bo to že držalo. Škoda le, da niso napisali še military grade... >:D

Dajmo malo bolj resno.

Torej. V OS-u imaš načeloma mehanizem, ki ti omogoča dostop do entropije. V Linuxu je to tipično posebna naprava /dev/random. Seveda pa ti ta vir entropije naključnih števil ne generira kar iz zraka. Tipično se za to uporabljajo razni algoritmi, po možnosti tudi dogodki (npr. dogodki na omrežju ali kakšen drug vir naključnih dogodkov), Intel pa ima pri nekaterih svojih procesorjih tudi extension, kjer lahko naključne podatke generira Intel. Ampak za Intel se sumi, da njihov RNG ni ravno nepristranski.

Opcija 2 je pa, da za input /dev/random uporabiš zunanjo napravo. Na primer ChaosKey.

Skratka, pomembno je, kar je v ozadju /dev/random - od tega je odvisno koliko cryptographically secure ta vir entropije sploh je.

Ko govorimo o determinističnem pridobivanju psevdo naključnih podatkov, se v praksi zanašamo na šifrirne algoritme. Zato pravimo, da je tak vir kriptografsko varen (dokler je algoritem praktično nezlomljen).

Povsem naključni podatki so veliko boljša izbira, dejansko povsem nedeterministični, ker jih ne pridobivamo z deterministično metodo, tj. šifrirnim algoritmom, pač pa opazujemo/zajemamo nek nedeterminističen pojav.

So pa tudi kombinirani načini, ko se iz neke omejene količine (s sejanjem) povsem naključnih podatkv pridobiva s šifrirnimi algoritmi večje psevdonaključne količine.

No, dobro, hvala za info. Sepravi je tista funkcija, ki jo je blackbfm napisal cisto ok? Ja, vem ni "true random". Ampak, ce pravis, da so PRNG algoritmi "zadosti random" bo ok. Ne pravim za military/government grade, bolj "plebs grade".

Pri spletnih streznikih, ki vse seje peljejo po SSL ta zadeva kar razbremeni proc., da ni potrebno računati s PRNG algoritmi. In se občutno pozna.

se profi test s programom iz http://www.fourmilab.ch/random/
Not bad for arduino based TRNG :)

F:\Zacasen\random>ent.exe chaosKey_entropy.txt
Entropy = 7.999638 bits per byte.

Optimum compression would reduce the size
of this 500000 byte file by 0 percent.

Chi square distribution for 500000 samples is 250.83, and randomly
would exceed this value 56.20 percent of the times.

Arithmetic mean value of data bytes is 127.4989 (127.5 = random).
Monte Carlo value for Pi is 3.141996568 (error 0.01 percent).
Serial correlation coefficient is -0.001135 (totally uncorrelated = 0.0).

Koliko bandwidtha?

bom zmeril

okoli 8kB/sekundo

imam pa nadgradnjo za Arduino v naslednji verziji. Zunanji ADC kjer lahko veliko hitreje beres in z vecjo natancnostjo.

p.s. Originalni z STM32 kontrolerjem ima vecji prenos kot arduino.

Če sem prav informiran, naj bi bila idealna Monte Carlo vrednost za Pi enaka pravemu Pi. Torej je "tvoja" vrednost (3.141996568) zelo v redu. Tudi entropija ter kompresija je videti zelo v redu.

Thumbs up!

Sem govoril s kolegom matematikom.

Pravi, da je dobro podatke zajemati kakšen teden in potem nad tistim narediti izračun, da so šele tam ti testi dovolj zanesljivi.

STM32 različica ima pasovno širino kot veliko, veliko dražje naprave! Za Arduino pa vsekakor ni slabo.

Vrnite nam techno!

Ce sem prav zracunal bi naj to bilo okoli 5Gb velik fajl. That's doable. Bom probal zajeti podatke v bljiznji prihodnosti.

Sem pa naredil korak naprej tudi z STM32 verzijo. 3.3V napajanje sedaj dela. elf fajle sem spremenil v bin.
Ni mi se jasno kako program zapect v STM32. Bootloader ni problem, to bom s stlink utility naredil. Samo ne vem pa kaj uporabit za chaoskey program.
Malo testiranja se v prihodnjih dneh.

Drugace pa zanimivi rezultati v objavi z dne 12. maja.

Sem naredil se malo vecje fajle zdaj k se hitreje berejo podatki

Entropy = 7.999967 bits per byte.

Optimum compression would reduce the size
of this 5000000 byte file by 0 percent.

Chi square distribution for 5000000 samples is 226.51, and randomly

Arithmetic mean value of data bytes is 127.4674 (127.5 = random).
Monte Carlo value for Pi is 3.140079656 (error 0.05 percent).

zgleda da vecji ko je fajl boljse je, kar je zelo dober indikator da je entropy pool random
p.s. to Je se vedno vse z arduinotom zajeto, ne z ARM32, tisto se pride...

Bravo, bravissimo. To je pa za IoT že kar uporabno!

Red_Mamba :: 3. jun 2018, 13:59

Quick update:

Z ARM-om zaenkrat nic uspeha. Mislim da je problem v tem ker uporabljam drugo ohisje kot original nacrt in zato koda, ki jo imam ne dela. Bom ob priliki poizkusil spisati svojo, samo da sprobam hitrost.

Delam pa na nadgradnji arduino verzije vmes ;)

btw, ce kdo hoce arduino verzijo, bo lahko dobil zlotanega kmalu.
Samo nekaj komponent moram se narocit in arduinote k mi je zmanjkalo.
Imel jih bom 10 komadov na voljo :))

se eno vprasanje glede arduinota. Trenutno je tako narejen program, da entropija skoz laufa in nonstop posilja podatke na USB
kljub temu da ni nic priklopljeno.

razmisljal sem da bi naprogramiral AT komande sistem kjer bi lahko vkplapljal izklaplajal entropijo in bi vracal random vrednosti samo na ukaz, ne nonstop. Je ena opcija za software ce komu bolj prav pride. Druhace se pa comport odpre v kateremkoli programskem jeziku in beres byte ven, ki so random iz entropije.

Kot sem ze pri prejsnjih testih videl je 1C najboljsi do sedaj

Daj na en servis, naloži par 8 MB datotek (ime naj bo _bandwidth*). Me zanima kako to ocenijo različni servisi.

*recimo: "random1.8000bps", "random2.6000bps" ali kaj podobnega.

imas url pri roki?

lahko ti pa tudi fajle posnamem in jih sam potestiras ;)

Diehard testi (ali Đorđevi - to smo včasih uporabljali), Monkey,... vsi pravijo, da so zadeve takšne, kot naj bi bile. "Pseudorandom comparison" je .26 (to mi je sumljivo - iz moje strani).

Imaš dober random generator. (Škoda, da nisi napisal bandwidtha. Sicer pa, kaj lahko nastaviš bandwidth? Tako kot pri nekaterih starih PCI karticah, ko smo šli nad neko mejo se je vse podrlo.)

bandwith je 30kB/s. Z malo tuninga prisel na 60kB/s. In zadnji testi so bili vsi zajeti z 60kB/s (tudi dieharder).
Bandwith sem nastavil dovolj nizko v kodi da se randomness ne podre 8-)

en update.

sestavil testno vezje na "vizitki" ki se poveze na rPi. Zadeva dela, ampak je trenutno precej pocasna. samo okoli 12kB/sec.
Overhead predstavlja sam linux driver. Moram zamenjat driver, ker bi morala teoreticno zadeva it precej hitreje kot to :)

Se pa izgram trenutno s svojo verzijo USB kljuca ki ima STM32 mikrokotrnoller. In zadeva zgleda precej obetavna.
Sedaj sem toliko kode za uC napisal, da lahko dejansko kaksen test pozenem ko dumpnem entropy pool v fajl.

A morda že veš koliko bi bila končna cena te RPi vizitke? Sama ploščica je kolikor vem poceni, kaj pa če daš vse skupaj še zalotati?

samo plato dobis zastonj, je delana kot business vizitka za firmo in nisem imel namena prodajati :)

Zlotana je pa v rangu nekje 10-20eur, ker ni na plati nic drugega kot par cipov ter upori in kondenzatorji.
Sem pa trenutni prisel s to vizitko na isto hitrost kot z mojim 1. prototipom ko sem bral z arduinotom (okoli 60kBajtov na sekundo)
Problem je da OS predstavlja precejsen overhead. Moram se potestirat koliko profitiram ce berem z STM32 to vizitko, ker ADC mora laufat z 3MSPS (3 miljone vzorcev na sekundo, 50x vec kot rPi bere trenutno)

Ta drugi test z USB kljucem so tudi precej obetavni. Hitrost branja okoli 250kBajtov, pri nekaterih algoritmih celo prek 350kB/s, samo nisem se dokoncal testov entropije.
Trenutno sem nastavil proto plato na jenkins, da lahko avtomatsko kodo kompilam in nalozim na usb kljuc (ima gor arduino bootloader za STM32F103xx cipe), sedaj moram dodati se
da zajame entropijo v fajle in potem pozene par ent in dieharder testov :)

nekaj kode je tudi ze v GIT: https://github.com/Mambix/ChaosDuino/bl...
