Kuburitswa kwebazi idzva rakagadzikana reTor 0.4.1

Introduced kusunungurwa kwezvishandiso Thor 0.4.1.5, inoshandiswa kuronga kushanda kweTor network isingazivikanwe. Tor 0.4.1.5 inozivikanwa seyokutanga yakagadzikana kusunungurwa kwebazi re 0.4.1, iro rave richigadzirwa kwemwedzi mina yapfuura. Bazi re0.4.1 richachengetwa sechikamu chenguva dzose yekugadzirisa - zvigadziriso zvichamiswa mushure memwedzi ye9 kana mwedzi mitatu mushure mekubudiswa kwebazi re 3.x. Tsigiro yenguva refu (LTS) inopihwa bazi re0.4.2, zvigadziriso zvichaburitswa kusvika Kukadzi 0.3.5, 1.

Zvitsva zvikuru:

• Tsigiro yekuyedza yecheni-level padding yakaitwa kuwedzera dziviriro kubva kuTor traffic yekuona nzira. Mutengi zvino anowedzera padding maseru pakutanga kwemaketani SUMIRA uye RENDEZVOUS, zvichiita kuti traffic pamaketani aya ive yakafanana neyenguva dzose inobuda traffic. Mutengo wekuwedzera kudzivirirwa ndeyekuwedzerwa kwemasero maviri ekuwedzera mune imwe neimwe nzira yeRENDEZVOUS maketani, pamwe chete nepamusoro pemvura uye 10 masero ekudzika kwemaketani eINTRODUCE. Iyo nzira inogadziriswa kana iyo MiddleNodes sarudzo inotsanangurwa muzvirongwa uye inogona kuremara kuburikidza neCircuitPadding sarudzo;
  

• Added rutsigiro rwechokwadi SENDME maseru kudzivirira kubva DoS inorwisa, zvichienderana nekugadzirwa kweparasitic load munyaya iyo mutengi anokumbira kurodha mafaira makuru uye kumbomira kuverenga mashandiro mushure mekutumira zvikumbiro, asi anoenderera mberi nekutumira SENDME mirairo yekudzora ichiraira mapikisi ekuisa kuti arambe achiendesa data. Sero rimwe nerimwe
  Iyo SENDME ikozvino inosanganisira hashi yetraffic yainobvuma, uye yekupedzisira node pakugamuchira SENDME sero inogona kuona kuti imwe bato yakatogamuchira traffic yakatumirwa pakugadzirisa masero apfuura;

• Chimiro chacho chinosanganisira kushandiswa kweiyo generalized subsystem yekutumira mameseji mumuparidzi-munyoreri modhi, iyo inogona kushandiswa kuronga intra-module yekudyidzana;
• Kupatsanura mirairo yekudzora, yakajairika parsing subsystem inoshandiswa pachinzvimbo chekuparadzanisa kupatsanurwa kweiyo data yekupinza yemurairo wega wega;
• Performance optimization yakaitwa kudzikisa mutoro paCPU. Tor ikozvino inoshandisa yakaparadzana inokurumidza pseudo-random nhamba jenareta (PRNG) kune yega yega shinda, iyo yakavakirwa pakushandiswa kweiyo AES-CTR encryption modhi uye kushandiswa kwebuffering inovaka se libottery uye itsva arc4random () kodhi kubva OpenBSD. Kune data diki rekubuda, jenareta yakatsanangurwa inokurumidza kanokwana ka1.1.1 kupfuura CSPRNG kubva kuOpenSSL 100. Kunyangwe iyo PRNG nyowani yakaverengerwa secryptographically yakasimba nevagadziri veTor, parizvino iri kungoshandiswa munzvimbo dzinoda kuita kwepamusoro, senge padding yekunamatira kodhi yekuronga;
• Yakawedzerwa sarudzo "--list-modules" kuratidza runyoro rwemamodule akagoneswa;
• Kune yechitatu vhezheni yeyakavanzika masevhisi protocol, iyo HSFETCH murairo wakaitwa, iyo yaimbove yakatsigirwa chete mune yechipiri vhezheni;
• Zvikanganiso zvakagadziriswa muTor launch kodhi (bootstrap) uye mukuona kushanda kweyechitatu vhezheni yeyakavanzika masevhisi protocol.
