Baye benza umfuniselo wokulinganisa inethiwekhi yeTor

Zimbalwa iintsuku ezidlulileyo baphandi evela kwiDyunivesithi yaseWaterloo kunye neLebhu yoPhando lwasemanzini yase-US. ibonise iziphumo zophuhliso lweTor network simulator ethelekiseka ngenani leendawo kunye nabasebenzisi kwinethiwekhi yeTor ephambili kwaye ivumela iimvavanyo ezikufutshane neemeko zokwenyani.

I-network modeling toolkit kunye nendlela yokusebenza eyenziwe ngexesha lovavanyo kuvunyelwe ukulinganisa ukusebenza kwenethiwekhi ye-6489 Tor nodes kwikhompyuter ene-4 TB ye-RAM, apho abasebenzisi abangamawaka angama-792 baqhagamshelwe ngaxeshanye.

Kufuneka kuqatshelwe ukuba olu lulinganiso olukhulu lokuqala lwenethiwekhi yeTor, inani leendawo ezihambelana nenethiwekhi yokwenyani. (Inethiwekhi yeTor esebenzayo inama-nodes angama-6 amawaka kunye ne-2 yezigidi zabasebenzisi abaxhunyiwe).

Ukulinganisa okupheleleyo kwenethiwekhi yeTor kunomdla malunga nokuchongwa kwe-bottleneck, imodeli yokuziphatha yokuhlaselwa, ukuvavanywa kobuchule obutsha bokuphucula phantsi kweemeko zobomi bokwenyani, kunye nobungqina beengcamango ezinxulumene nokhuseleko.

Ngesifanisi esipheleleyo, Abaphuhlisi beTor baya kukwazi ukuhamba kude nomsebenzi wokuqhuba iimvavanyo kwi-mainnet okanye kwii-nodes iindawo zokusebenzela zomntu ngamnye, odala imingcipheko eyongezelelweyo yokwaphula ubumfihlo bomsebenzisi kwaye ayiphelisi ukusilela. Ngokomzekelo, kwiinyanga ezizayo, i-Tor ilindeleke ukuba iqalise inkxaso yeprotocol entsha yokulawula ukuxinana, kwaye ukulinganisa kuya kukuvumela ukuba ufunde ngokupheleleyo indlela esebenza ngayo ngaphambi kokuyiphumeza kwinethiwekhi yangempela.

Ukongeza ekupheliseni impembelelo yovavanyo kwimfihlo kunye nokuthembeka kwee inethiwekhi yeTor engundoqo, ubukho beetestnets ezahlukeneyo buya kwenza ukuba kukwazi ukuvavanya ngokukhawuleza kunye nokulungisa ikhowudi entsha ngexesha lophuhliso, ukuhambisa utshintsho ngokukhawuleza kuzo zonke iindawo kunye nabasebenzisi ngaphandle kokulinda ukuthunyelwa kwexesha elide eliphakathi ukugqibezela, ukwakha kunye nokuqhuba iiprototypes ngokukhawuleza ngokuphunyezwa. yemibono emitsha.

Umsebenzi uyenziwa ukuphucula i-toolkit leyo, ngokutsho kwabaphuhlisi, iya kunciphisa ukusetyenziswa kwezixhobo ngamaxesha angama-10 kwaye iya kuvumela ukusebenza kwenethiwekhi ezigqithisa inethiwekhi yangempela ukuba ifaniswe kwikhompyutheni efanayo, enokuthi ibe yimfuneko ukuchonga iingxaki ezinokwenzeka. . kunye neTor yokukala. Ebudeni bomsebenzi, iindlela ezininzi zokubonisa inethiwekhi entsha ziye zadalwa ezenza ukuba kube lula ukuqikelela utshintsho kwimeko yenethiwekhi ngokuhamba kwexesha kunye nokusebenzisa iijenereyitha zendlela yangasemva ukulinganisa umsebenzi wabasebenzisi.

Abaphandi Kwakhona wafunda ipateni phakathi kobukhulu bothungelwano olufanisiweyo kunye nokuthembeka kokubonisa iziphumo yeemvavanyo kuthungelwano lokwenyani. Ngexesha lophuhliso lweTor, utshintsho kunye nokulungiswa kwangaphambili kuvavanywa kuthungelwano oluncinci lovavanyo, oluqulethe iinodi ezimbalwa kunye nabasebenzisi kunenethiwekhi yokwenyani.

Kwafunyaniswa ukuba iimpazamo zezibalo zoqikelelo olufunyenweyo ngexesha lokulinganisa okuncinci kunokubuyiselwa ngokuphinda-phindwa kovavanyo oluzimeleyo kunye neeseti zedatha ezahlukeneyo, ngelixa inkulu inethiwekhi efanisiweyo, ukuvavanya kwakhona okumbalwa kuyafuneka ukufumana izigqibo ezibalulekileyo.

Ukwenza imodeli kunye nokulinganisa inethiwekhi yeTor, abaphandi baphuhlisa iiprojekthi ezininzi ezivulelekileyo ezisasazwa phantsi kwelayisensi ye-BSD:

  • Isithunzi: I-simulator yenethiwekhi yendalo yonke ekuvumela ukuba usebenzise ikhowudi yesicelo senethiwekhi yokwenyani ukuphinda usebenze iinkqubo ezisasazwayo kunye namawaka eenkqubo zenethiwekhi. Ukulinganisa iinkqubo ezisekelwe kwizicelo zokwenyani ezingalungiswanga.
  • Tornettools: Iseti yezixhobo zokuvelisa iimodeli zokwenyani zenethiwekhi yeTor ezinokuqhutywa kwindawo yeSithunzi, kunye nokusebenza kunye nokwenza inkqubo yokulinganisa, ukuqokelela kunye nokubona iziphumo. Iimethrikhi ezibonisa ukusebenza kwenethiwekhi yeTor yokwenyani zinokusetyenziswa njengeetemplates zokwenziwa kwenethiwekhi.
  • TGen: i-generator ye-traffic flows esekelwe kwiiparameters ezisekwe ngumsebenzisi (ubukhulu, ukulibaziseka, inani lokuhamba, njl.). Izikimu zokubunjwa kweTrafikhi zinokusekwa ngokusekelwe kwimiba ekhethekileyo kwifomathi yeGraphML kunye nokusebenzisa imifuziselo yeMarkov enokwenzeka yokusasazwa kwemijelo kunye neepakethi zeTCP.
  • OnionTrace: iseti yezixhobo zokubeka iliso kwintsebenzo kunye neziganeko kwinethiwekhi yeTor efanisiweyo, kunye nokurekhoda kunye nokuphinda udlale ulwazi malunga nokwakhiwa kwamakhonkco e-Tor nodes kunye nokudibanisa ukuhamba kwezithuthi kubo.

Okokugqibela, ukuba unomdla wokwazi ngakumbi ngayo, ungajongana neenkcukacha kwi ukulandela ikhonkco.
