Ofufuza ochokera ku yunivesite ya Waterloo ndi US Naval Research Laboratory adapereka zotsatira za chitukuko cha Tor network simulator, yofanana ndi chiwerengero cha node ndi ogwiritsa ntchito pa intaneti yaikulu ya Tor ndikulola kuyesa pafupi ndi zochitika zenizeni. Zida ndi njira zowonetsera maukonde zomwe zidakonzedwa panthawi yoyeserera zidapangitsa kuti pakompyuta yokhala ndi 4 TB ya RAM, kutsanzira kugwiritsa ntchito maukonde a 6489 Tor node, pomwe ogwiritsa ntchito pafupifupi 792 sauzande amalumikizidwa nthawi imodzi.
Zimadziwika kuti uku ndiko kuyerekezera koyamba kwapaintaneti ya Tor, kuchuluka kwa node komwe kumafanana ndi netiweki yeniyeni (network ya Tor yogwira ntchito ili ndi ma node pafupifupi 6 ndi ogwiritsa ntchito 2 miliyoni). Kuyerekeza kwathunthu kwa netiweki ya Tor ndikosangalatsa kuchokera pamalingaliro ozindikira zolepheretsa, kutsanzira machitidwe owukira, kuyesa njira zatsopano zokwaniritsira munthawi yeniyeni, ndikuyesa malingaliro okhudzana ndi chitetezo.
Ndi simulator yodzaza ndi zonse, opanga Tor adzatha kupewa chizolowezi choyesa pamaneti yayikulu kapena pa node ya munthu aliyense wogwira ntchito, zomwe zimapangitsa kuti pakhale zoopsa zina zophwanya zinsinsi za ogwiritsa ntchito ndipo osapatula kuthekera kwa kulephera. Mwachitsanzo, kuthandizira kwa protocol yatsopano yowongolera kusokonekera kumayembekezeredwa kuyambitsidwa ku Tor m'miyezi ikubwerayi, ndipo kuyerekezerako kudzatilola kuti tiphunzire mokwanira ntchito yake tisanatumizidwe pa intaneti yeniyeni.
Kuphatikiza pakuchotsa kukhudzidwa kwa zoyeserera pachinsinsi komanso kudalirika kwa netiweki yayikulu ya Tor, kukhalapo kwa maukonde osiyanasiyana oyesa kumapangitsa kuti athe kuyesa mwachangu ndikuwongolera ma code atsopano panthawi yachitukuko, nthawi yomweyo sinthani zosintha za node zonse ndi ogwiritsa ntchito popanda. kuyembekezera kukwaniritsidwa kwa nthawi yayitali yapakatikati, pangani mwachangu ndikuyesa ma prototypes ndikukhazikitsa malingaliro atsopano.
Ntchito ikuchitika pofuna kukonza zida, zomwe, monga zanenedwa ndi opanga, zidzachepetsa kugwiritsidwa ntchito kwazinthu ndi nthawi za 10 ndipo zidzalola, pazida zomwezo, kutsanzira ntchito ya maukonde omwe ali apamwamba kuposa maukonde enieni, omwe angafunike. kuzindikira zovuta zomwe zingatheke pakukulitsa Tor. Ntchitoyi idapanganso njira zingapo zatsopano zowonetsera maukonde zomwe zimapangitsa kuti zitheke kulosera zakusintha kwa maukonde pakapita nthawi ndikugwiritsa ntchito majenereta am'mbuyo am'mbuyo kuti ayese ntchito ya ogwiritsa ntchito.
Ofufuzawo adaphunziranso chitsanzo chapakati pa kukula kwa maukonde ofananitsa ndi kudalirika kwa zotsatira zoyesera pa intaneti yeniyeni. Panthawi yachitukuko cha Tor, zosintha ndi kukhathamiritsa zimayesedwa kale pamanetiweki ang'onoang'ono oyesa omwe amakhala ndi ma node ochepa komanso ogwiritsa ntchito kuposa maukonde enieni. Zinapezeka kuti zolakwika zowerengera pazolosera zomwe zapezedwa kuchokera kuzinthu zazing'ono zimatha kulipidwa pobwereza zoyeserera zodziyimira pawokha kangapo ndi magulu osiyanasiyana a data yoyambira, popeza kukula kwa netiweki yoyeserera, kuyezetsa kobwerezabwereza kochepa kumafunikira kuti mupeze ziganizo zofunika kwambiri.
Kuti awonetsere komanso kutsanzira ma network a Tor, ofufuza akupanga ma projekiti angapo otseguka omwe amagawidwa pansi pa layisensi ya BSD:
- Shadow ndi pulogalamu yapaintaneti yapadziko lonse lapansi yomwe imakupatsani mwayi wogwiritsa ntchito nambala yeniyeni yogwiritsira ntchito netiweki kuti mukonzenso makina omwe adagawidwa ndi masauzande a ma network. Kutengera machitidwe otengera zenizeni, zosasinthidwa, Shadow amagwiritsa ntchito njira zotsatsira mafoni. Kulumikizana kwa maukonde pamakina ofananirako kumachitika kudzera pakutumiza kwa VPN ndikugwiritsa ntchito ma simulators a ma protocol wamba (TCP, UDP). Imathandizira kayesedwe kazinthu zapaintaneti monga kutayika kwa paketi ndi kuchedwa kubweretsa. Kuphatikiza pazoyeserera ndi Tor, kuyesa kudapangidwa kuti apange pulogalamu yowonjezera ya Shadow kuti ifanane ndi netiweki ya Bitcoin, koma ntchitoyi sinapangidwe.
- Tornettools ndi chida chopangira zitsanzo zenizeni za netiweki ya Tor zomwe zimatha kuyendetsedwa mu Shadow chilengedwe, komanso poyambitsa ndikusintha kayesedwe, kutolera ndikuwona zotsatira. Ma metric omwe amawonetsa magwiridwe antchito a netiweki yeniyeni ya Tor atha kugwiritsidwa ntchito ngati ma template opangira maukonde.
- TGen ndi jenereta wa kayendedwe ka magalimoto kutengera magawo omwe amafotokozedwa ndi wogwiritsa ntchito (kukula, kuchedwa, kuchuluka kwamayendedwe, etc.). Mawonekedwe amtundu wa magalimoto amatha kufotokozedwa potengera zolemba zapadera zamtundu wa GraphML komanso kugwiritsa ntchito mitundu ya Markov yotheka pogawa mayendedwe ndi mapaketi a TCP.
- OnionTrace ndi chida chowunikira magwiridwe antchito ndi zochitika mu netiweki ya Tor, komanso kujambula ndi kuseweretsa zambiri za mapangidwe a maunyolo a Tor node ndikuwapatsa mayendedwe oyenda.
