Benze isilingo belingisa inethiwekhi ye-Tor

Zimbalwa izinsuku ezedlule abacwaningi evela eNyuvesi yaseWaterloo kanye nase-US Naval Research Laboratory. yethule imiphumela yokuthuthukiswa kwesilingisi senethiwekhi ye-Tor eqhathaniswa ngenani lama-node nabasebenzisi kunethiwekhi ye-Tor eyinhloko futhi ivumela ukuhlolwa okuseduze nezimo zangempela.

Ikhithi yamathuluzi emodeli yenethiwekhi nendlela yokusebenza eyenziwe ngesikhathi sokuhlolwa ivunyelwe ukulingisa ukusebenza kwenethiwekhi ye-6489 Tor nodes kukhompyutha ene-4 TB ye-RAM, lapho abasebenzisi be-virtual abayizinkulungwane ezingama-792 baxhumeke ngasikhathi sinye.

Kumele kuqashelwe ukuthi lokhu ukulingisa kokuqala okukhulu kwenethiwekhi ye-Tor, inani lamanodi ahambisana nenethiwekhi yangempela. (Inethiwekhi ye-Tor esebenzayo inamanodi angaba yizinkulungwane ezingu-6 kanye nabasebenzisi abaxhunyiwe abayizigidi ezingu-2).

Ukulingisa okuphelele kwenethiwekhi ye-Tor kuyathakazelisa mayelana nokuhlonza izingqinamba, ukuziphatha ngendlela eyimodeli yokuhlasela, ukuhlola amasu amasha okuthuthukisa ngaphansi kwezimo zempilo yangempela, kanye nobufakazi bemiqondo ehlobene nokuvikeleka.

Nge-simulator ephelele, Abathuthukisi be-Tor bazokwazi ukuqhela kumkhuba wokwenza izivivinyo ku-mainnet noma kuma-node izindawo zokusebenzela ngazinye, okudala izingozi ezengeziwe zokwephula ubumfihlo bomsebenzisi futhi akususi ukuba nokwenzeka kokwehluleka. Isibonelo, ezinyangeni ezizayo, i-Tor kulindeleke ukuthi yethule ukusekelwa kwephrothokholi entsha yokulawula ukuminyana, futhi ukulingisa kuzokuvumela ukuthi ufunde ngokugcwele ukuthi isebenza kanjani ngaphambi kokuyisebenzisa kunethiwekhi yangempela.

Ngaphezu kokuqeda umthelela wokuhlolwa ekugcinweni kuyimfihlo nokuthembeka kwe-e inethiwekhi ye-Tor eyinhloko, ukuba khona kwama-testnet ahlukene kuzokwenza kube lula ukuhlola nokulungisa iphutha ngokushesha ikhodi entsha ngesikhathi sokuthuthukiswa, hambisa izinguquko ngokushesha kuwo wonke ama-node nabasebenzisi ngaphandle kokulinda ukuthunyelwa okuphakathi okude ukuqedela, ukwakha nokusebenzisa ama-prototypes ngokushesha ngokuqaliswa. yemibono emisha.

Kwenziwa umsebenzi wokuthuthukisa ikhithi yamathuluzi okuthi, ngokusho kwabathuthukisi, izonciphisa ukusetshenziswa kwezinsiza izikhathi ezingu-10 futhi izovumela ukusebenza kwamanethiwekhi adlula inethiwekhi yangempela ukuba ifaniswe kukhompyutha efanayo, okungase kudingeke ukuhlonza izinkinga ezingenzeka. . ngokukala kwe-Tor. Ngokuqhubeka komsebenzi, kuye kwadalwa izindlela ezimbalwa zokumodela zenethiwekhi ezenza kube nokwenzeka ukubikezela ushintsho esimweni senethiwekhi ngokuhamba kwesikhathi futhi kusetshenziswe amajeneretha ethrafikhi angemuva ukuze alingise umsebenzi womsebenzisi.

Abaphenyi iphinde yafunda iphethini phakathi kosayizi wenethiwekhi elingisiwe kanye nokuthembeka kokuphrojusa imiphumela yokuhlolwa kunethiwekhi yangempela. Ngesikhathi sokuthuthukiswa kwe-Tor, izinguquko nokulungiselelwa kuhlolwa kuqala kumanethiwekhi amancane okuhlola, aqukethe ama-node nabasebenzisi abambalwa kakhulu kunenethiwekhi yangempela.

Kutholwe ukuthi amaphutha ezibalo ezibikezelo ezitholwe ngesikhathi sokulingiswa okuncane anganxeshezelwa ngokuphindaphinda okuphindaphindiwe kokuhlolwa okuzimele ngamasethi edatha ahlukene okuqala, kuyilapho inkulu inethiwekhi elingisiwe, ukuhlolwa kabusha okumbalwa kuyadingeka ukuze kutholwe iziphetho ezibalulekile zezibalo.

Ukumodela nokulingisa inethiwekhi ye-Tor, abacwaningi bakha amaphrojekthi amaningi omthombo ovulekile asatshalaliswa ngaphansi kwelayisensi ye-BSD:

  • Isithunzi: i-simulator yenethiwekhi yendawo yonke evumela ukuthi usebenzise ikhodi yohlelo lokusebenza lwenethiwekhi yangempela ukuze udale kabusha ukusebenza kwezinhlelo ezisabalalisiwe ngezinkulungwane zezinqubo zenethiwekhi. Ukulingisa amasistimu asuselwe kuzinhlelo zokusebenza ezingaguquliwe zangempela.
  • Ama-Tornettools: isethi yamathuluzi okukhiqiza amamodeli angokoqobo enethiwekhi ye-Tor angasetshenziswa endaweni Yethunzi, kanye nokuqalisa nokwenza ngendlela oyifisayo inqubo yokulingisa, ukuqongelela kanye nokubona imiphumela. Amamethrikhi abonisa ukusebenza kwenethiwekhi ye-Tor yangempela angasetshenziswa njengezifanekiso zokwenziwa kwenethiwekhi.
  • TGen: ijeneretha yokugeleza kwethrafikhi ngokusekelwe kumapharamitha asungulwe umsebenzisi (usayizi, ukubambezeleka, inani lokugeleza, njll.). Izikimu zokuma kwethrafikhi zingasungulwa ngokusekelwe kuzimo ezikhethekile kufomethi ye-GraphML futhi kusetshenziswa amamodeli we-Markov okungenzeka ukuthi asabalalise ama-TCP namaphakethe.
  • OnionTrace: isethi yamathuluzi okuqapha ukusebenza nemicimbi kunethiwekhi ye-Tor elingisiwe, kanye nokurekhoda nokudlala kabusha ulwazi olumayelana nokwakhiwa kwamaketanga ama-Tor node nokuxhuma ukugeleza kwethrafikhi kuwo.

Okokugcina, uma ungathanda ukwazi okwengeziwe ngakho, ungathintana nemininingwane ku isixhumanisi esilandelayo.
