Muva nje ICloudflare Inkampani Yethule I-League of Entropy Service, ngokuhlinzwa lokho Kwakhiwa kuzungeza ukuhlangana kwezinhlangano ezahlukahlukene ezinentshisekelo ekunikezeni izinombolo ezingahleliwe.
Ngokungafani nezinhlelo ezikhona ezikhona, I-League of Entropy ayisuselwe emthonjeni owodwa futhi isetshenziselwa ukukhiqiza ukulandelana okungahleliwe kwe-entropy etholwe kuma-generator amaningi engahlobene ilawulwa abahlanganyeli abahlukile bephrojekthi.
Ngenxa yokusatshalaliswa kwephrojekthi, ukuyekethisa noma ukuqamba amanga komthombo owodwa noma emibili ngeke kuholele ekwenziweni kwenombolo yokugcina engahleliwe.
Kumele kuqashelwe ukuthi izinombolo ezakhiwe ezingahleliwe zingaphansi kwesigaba sokulandelana okutholakala esidlangalaleni lokho akunakusetshenziselwa ukukhiqiza okhiye bokubethela nasezindaweni lapho inombolo engahleliwe kufanele igcinwe iyimfihlo.
Le nsizakalo ihlose ukuhlinzeka ngezinombolo ezingahleliwe ezingenakubikezelwa kusengaphambili, kepha ngemuva kokwenza lezi zinombolo zitholakala esidlangalaleni, ngisho nokuhlola ukunemba kwamanani angahleliwe adluliselwe kuwo.
Isebenza kanjani i-League of Entropy?
Izinombolo zomphakathi ezingahleliwe zenziwa njalo ngemizuzwana engama-60. Inombolo ngayinye ihlotshaniswa nenombolo yayo yokulandelana (nxazonke), ngakho-ke nganoma yisiphi isikhathi futhi kunoma iyiphi i-server yelungu ungathola inani elakhiwe kanye.
Lezi zinombolo ezingahleliwe zingasetshenziswa ezinhlelweni ezisatshalalisiwe, ama-cryptocurrensets kanye nama-blockchains, lapho ama-node ahlukile kufanele akwazi ukufinyelela ku-generator eyodwa wezinombolo ezingahleliwe (ngokwesibonelo, lapho kwakhiwa ubufakazi bomsebenzi owenziwayo), kanye nalapho wenza ama-lotto ahlukahlukene kanye nokwenza amasampula angahleliwe ngesikhathi sokuhlolwa kokuvunywa kokhetho.
Ukusebenza nensizakalo nokuhambisa amayunithi abo amathuluzi we-Drand ahlongozwayo, abhalwe ku-Go futhi athengiswa ngaphansi kwelayisense ye-MIT.
IDrand isebenza ngendlela yenqubo engemuva, ehlotshaniswa nama-generator angaphandle abamba iqhaza kunethiwekhi esatshalaliswayo futhi ngokuhlanganyela bakha inani lesifinyezo elingahleliwe.
Inani le-pivot lenziwa kusetshenziswa i-threshold cryptography nezindlela zokufanisa ze-bilinearl. Ukwenza inani elihlanganisiwe lokungahleliwe kungenziwa ohlelweni lomsebenzisi ngaphandle kokubandakanya abahlanganisi abaphakathi.
IDrand nayo ingasetshenziselwa ukuletha izinombolo ezizimele ezakhiwe endaweni yangakini kumakhasimende.
Ukudlulisa inombolo engahleliwe, kusetshenziswa uhlelo lokubethela lwe-ECIES, lapho iklayenti lenza khona ukhiye wangasese nowomphakathi.
Ukhiye womphakathi udluliselwa kuseva kusuka eDrand. Inombolo engahleliwe ibethelwe kusetshenziswa lo khiye womphakathi futhi kungabonakala kuphela kwiklayenti elingumnikazi wokhiye oyimfihlo.
Isiphakamiso sokugwema ukukhwabanisa
Njengamanje, izinkampani nezinhlangano ezinhlanu zijoyine uhlelo lwe-League of Entropy, olunikeze ukufinyelela kuma-generator alo entropy.
Manje, ungahle ucabange ukuthi ukusebenzisa i-randomization beacon yezinqubo zokukhiqiza okungahleliwe, njengalezo ezidingekayo ekukhetheni i-lottery, kungenza inqubo imelane nokuphazamiseka okungalungile.
Abahlanganyeli bafakiwe kuphrojekthi atholakala emazweni ahlukene futhi sebenzisa izindlela ezahlukahlukene ukuthola i-entropy:
ICloudflare, iLavaRand: amanani angahleliwe akhiwa ngesisekelo sokugeleza okungalindelekile kuketshezi kumalambu e-lava, izithombe ezisebenza njenge-entropy yokufaka ye-CSPRNG (i-Cryptographically Secure Pseudo-Random Number Generator);
IYunivesithi yaseChile isebenzisa inethiwekhi yezinzwa zokuzamazama komhlaba kanye nomthombo we-entropykanye nedatha yomsakazo, umsebenzi we-Twitter, izinguquko ze-Ethereum blockchain, kanye ne-generator ye-hardware RNG eyenziwe ngokwakho.
Ukuphepha kweKudelski, ChaChaRand, inikeza i-CRNG (i-Cryptographic Random Number Generator) ngokuya ngokusetshenziswa kokubethela kwe-ChaCha20.
Ama-Protocol Labs, i-InterplanetaryRand, idatha engahleliwe ikhishwa kwabamukeli bomsindo futhi ihlanganiswe ne-Linux PRNG kanye ne-pseudo-random number generator eyakhelwe i-CPU.
Njengamanje, ababambiqhaza abazimele baqhuba izindawo ezine-8 zomphakathi ze-API, lapho ungafunda ngazo zombili izinombolo ezikhona ezingahleliwe zamanje.
