Kuburitswa kweTor 0.4.7.7 toolkit, yakashandiswa kuronga kushanda kweTor network isingazivikanwe, yaratidzwa. Tor version 0.4.7.7 inozivikanwa seyokutanga yakagadzikana kusunungurwa kwebazi re 0.4.7, iro rave richigadzirwa kwemwedzi gumi yapfuura. Bazi re0.4.7 richachengetwa sechikamu chegadziriro yenguva dzose - zvigadziriso zvichamiswa mushure memwedzi ye9 kana mwedzi mitatu mushure mekubudiswa kwebazi re 3.x.
Shanduko huru mubazi idzva:
- Yakawedzerwa kuisirwa kwecongestion control protocol (RTT Congestion Control), iyo inoronga traffic kuburikidza neTor network (pakati pemutengi uye yekubuda node kana hanyanisi sevhisi). Iyo protocol ine chinangwa chekudzikisira saizi yemitsara yekudzosera uye kukunda zvazvino zvinogumira. Kusvika parizvino, kumhanya kwerukova rwekudhawunirodha kuburikidza nekubuda node uye masevhisi ehanyanisi aive akaganhurirwa ku1 MB/sec, sezvo hwindo rekutumira rine saizi yakagadziriswa yemaseru zana parukova uye 1000 bytes yedata inogona kutumirwa musero rega rega (kuyerera mwero. neketani inononoka ye 512 sec = 0.5 * 1000 / 512 = ~ 0.5 MB / sec).
Kufanotaura mabudisiro aripo uye kuona saizi yemutsara wepacket, protocol nyowani inoshandisa Round Trip Time (RTT) fungidziro. Kufananidzira kwakaratidza kuti kushandiswa kweprotocol itsva pakubuda node uye masevhisi ehanyanisi kuchaita kuti kuderedzwa kwekunonoka kwemitsara, kubviswa kwezvirambidzo zvekuyerera, kuwedzera kwekuita kweTor network uye kunyanya kushandisa kwakaringana kwebandwidth iripo. Client-side flow control support ichapihwa muna Chivabvu 31st mukuburitswa kukuru kunotevera kweTor Browser, yakavakirwa paTor 0.4.7 bazi.
- Yakawedzerwa dziviriro yakareruka yeVanguards-lite kurwisa de-anonymization kurwiswa kweanyanisi enguva pfupi, izvo zvinoderedza njodzi yekuona nzvimbo dzekuchengetedza onion kana mutengi wehanyanisi mumamiriro ezvinhu apo sevhisi yanga ichimhanya isingasviki mwedzi (yehanyanisi. masevhisi anomhanya kweanopfuura mwedzi, zvinokurudzirwa kushandisa vanguards kuwedzera). Chinhu cheiyo nzira ndechekuti vatengi vehanyanisi nemasevhisi vanongosarudza 4-refu-running guard nodes ("layer 2 guard relay") kuti ishandiswe pakati pecheni uye node idzi dzinochengeterwa nguva isina kurongeka (paavhareji pavhiki) .
- Kumaseva edhairekitori, zvino zvinogoneka kupa MiddleOnly mureza kune relay uchishandisa nzira nyowani yekuzadzisa kubvumirana. Iyo nzira nyowani inosanganisira kufambisa iyo logic yekuseta MiddleOnly mureza kubva padanho remutengi kuenda kune directory server side. Kune relays yakanyorwa MiddleOnly, iyo Exit, Guard, HSDir uye V2Dir mireza inocheneswa otomatiki, uye BadExit mureza unoiswa.
