Vatsvagiri kubva kuYunivhesiti yeWaterloo neUS Naval Research Laboratory vakapa mhedzisiro yekuvandudzwa kweTor network simulator, inofananidzwa nenhamba yemanodhi nevashandisi kune mainTor network uye ichibvumidza kuyedza padyo nemamiriro chaiwo. Zvishandiso uye network modeling methodology yakagadzirirwa panguva yekuedza yakaita kuti zvikwanisike, pakombiyuta ine 4 TB ye RAM, kutevedzera kushanda kwetiweki ye6489 Tor nodes, iyo 792 zviuru zvevashandisi vanobatanidzwa panguva imwe chete.
Zvinocherechedzwa kuti iyi ndiyo yekutanga yakazara-chiyero simulation yeTor network, nhamba yemanodhi mairi inofanana neiyo chaiyo network (iyo inoshanda Tor network ine zviuru zvitanhatu node uye 6 miriyoni yakabatana vashandisi). Iyo yakazara simulation yeTor network ndeyekufarira kubva pakuona kwekuona mabhodhoro, kutevedzera kurwisa maitiro, kuyedza nzira nyowani dzekugadzirisa mumamiriro ezvinhu chaiwo, uye kuyedza pfungwa dzine chekuita nekuchengetedza.
Iine yakazara-yakazara simulator, Vagadziri veTor vanozokwanisa kudzivirira tsika yekuitisa zviedzo panetiweki huru kana pane mumwe mushandi node, izvo zvinogadzira imwe njodzi yekutyora kuvanzika kwevashandisi uye usabvisa mukana wekutadza. Semuenzaniso, kutsigirwa kweiyo nyowani congestion control protocol inotarisirwa kuunzwa muTor mumwedzi iri kuuya, uye simulation ichatibvumira kudzidza zvizere kushanda kwayo tisati tatumirwa kune network chaiyo.
Pamusoro pekubvisa kukanganiswa kwezviyedzo pakuvanzika uye kuvimbika kweiyo huru Tor network, kuvapo kweakaparadzana bvunzo network kuchaita kuti zvikwanise kukurumidza kuyedza uye kugadzirisa kodhi nyowani panguva yekusimudzira, nekukurumidza ita shanduko kune ese manode nevashandisi pasina. kumirira kupedzwa kwekuita kwenguva refu kwepakati, gadzira nekukurumidza uye kuyedza prototypes nekuita kwemazano matsva.
Basa riri kuenderera mberi rekuvandudza maturusi, ayo, sezvakataurwa nevagadziri, anoderedza kushandiswa kwezviwanikwa nekagumi uye anobvumira, pamidziyo imwe chete, kutevedzera kushanda kwemanetiweki ari pamusoro kune network chaiyo, inogona kudiwa. kuona matambudziko anogona kuitika neTor kuyera. Iro basa rakagadzirawo akati wandei nzira nyowani dzekuenzanisira dzinoita kuti zvikwanise kufanotaura shanduko yemamiriro etiweki nekufamba kwenguva uye kushandisa majenareta ekumashure kutevedzera chiitiko chemushandisi.
Vatsvakurudzi vakadzidzawo maitiro pakati pehukuru hwetiweki yakafananidzirwa uye kuvimbika kwekufungidzira kwemigumisiro yekuedza pane network chaiyo. Munguva yeTor budiriro, shanduko uye optimizations inofanoedzwa padiki bvunzo network ine mashoma mashoma node nevashandisi pane chaiyo network. Zvakaonekwa kuti zvikanganiso zvenhamba mukufembera zvakawanikwa kubva mukuenzanisa kudiki zvinogona kubhadharwa nekudzokorora kuedza kwakazvimiririra kakawanda nemaseti akasiyana e data rekutanga, zvichipihwa kuti yakakura inetiweki yakateedzerwa, mashoma akadzokororwa bvunzo anodiwa kuti uwane mhedzisiro yakakosha.
Kutevedzera uye kutevedzera Tor network, vaongorori vari kugadzira akati wandei akavhurika mapurojekiti akagoverwa pasi peiyo BSD rezinesi:
- Mvuri ndeye universal network simulator iyo inokutendera iwe kuti umhanye chaiyo network application kodhi kudzoreredza akagoverwa masisitimu nezviuru zvetiweki maitiro. Kutevedzera masisitimu akavakirwa pane chaiwo, asina kuchinjwa mashandisirwo, Mvuri inoshandisa system yekufona emulation matekiniki. Kudyidzana kwenetiweki kwezvikumbiro munzvimbo inofananidzwa kunoitwa kuburikidza nekutumirwa kweVPN uye kushandiswa kwemasimulators ezvakajairwa network protocol (TCP, UDP). Inotsigira yetsika simulation yechaiyo network maitiro senge kurasikirwa kwepaketi uye kunonoka kuburitsa. Pamusoro pezviyedzo neTor, kuyedza kwakaitwa kugadzira plugin yeShadow kutevedzera iyo Bitcoin network, asi chirongwa ichi hachina kugadzirwa.
- Tornettools chishandiso chekugadzira echokwadi mamodheru eTor network anogona kumhanya munzvimbo yeMvuri, pamwe nekutanga nekugadzirisa maitiro ekufananidza, kuunganidza nekuona mhedzisiro. Metrics anoratidza kushanda kweiyo chaiyo Tor network inogona kushandiswa sematemplate ekugadzira network.
- TGen ijenareta yekuyerera kwetraffic zvichienderana nematanho anotsanangurwa nemushandisi (saizi, kunonoka, nhamba yekuyerera, nezvimwewo). Zvirongwa zvekuumbwa kweTraffic zvinogona kutsanangurwa zvese zvichibva pane akakosha zvinyorwa muGraphML fomati uye kushandisa probabilistic Markov modhi yekugovera TCP inoyerera nemapaketi.
- OnionTrace chishandiso chekutevera mashandiro uye zviitiko mune inoteedzerwa Tor network, pamwe nekurekodha uye kudzokorodza ruzivo nezve kuumbwa kwemaketani eTor node uye kugovera traffic inoyerera kwavari.
