Mazuva mashoma apfuura yakaburitswa kuburikidza neTor blog post, uyel kuvhurwa kweTor 0.4.1.5 maturusi yaishandiswa kuronga basa reasina kuzivikanwa Tor network.
Iyi vhezheni itsva ye Tor 0.4.1.5 inozivikanwa seyekutanga vhezheni yakagadzika yebazi 0.4.1, izvo zvakagadziriswa mumwedzi mina yekupedzisira. Bazi 0.4.1 ichave ichiperekedzwa neyakajairwa yekuchengetedza kutenderera: kuburitswa kwemashure kuchamiswa mwedzi mipfumbamwe kana mwedzi mitatu mushure mekuburitswa kwebazi 9 uye mukuwedzera iyo refu yekutsigira kutenderera inopihwa (LTS) yebazi 0.3.5, vane zvinyorwa zvichaburitswa kusvika Kukadzi 1, 2022.
Kune avo vachiri kusaziva nezve iyo Tor chirongwa (Iyo Onion Router). Ichi chirongwa chine tarisiro huru kuvandudza network yekutaurirana yakagoverwa ne low latency uye yakasimudzwa pamusoro pe internet, umo kufambiswa kwemashoko kuchinjana pakati pevashandisi hakuratidze hunhu hwavo, ndiko kuti, iyo IP kero (kusazivikanwa padanho reneti) uye izvo, mukuwedzera, inochengetedza kuvimbika uye kuvanzika kweruzivo rwunofamba napo.
Iyo sisitimu yakagadzirirwa nekuchinjika kunodiwa kuitira kuti ikwanise kuita kuvandudzwa, kuendeswa mune chaiko nyika uye inogona kumira mhando dzakasiyana dzekurwisa. Nekudaro, ine isina kusimba mapoinzi uye haigone kutariswa seyakaoma system.
Chii chitsva mubazi idzva reTor 0.4.1
Nokuburitswa kwebazi idzva rakatsiga, rutsigiro rwekuyedza rwekuwedzera kuzadza padanho reketani rakaitwa, iyo inobvumidza kusimbisa iko kudzivirirwa panzira dzekuona Tor traffic.
Mutengi ikozvino anowedzera padding maseru pakutanga kweIYO INTRODUCE uye RENDEZVOUS tambo, zvichiita kuti traffic mune tambo idzi dzive senge wenguva dzose inobuda traffic.
Ipo iyo kudzivirirwa kudzivirirwa ndiko kuwedzerwa kwemamwe maseru ekuwedzera munzira yega yega yeiyo RENDEZVOUS tambo, pamwe chete nesero hombe uye gumi maseru makuru etambo INTRODUCE. Maitiro anopisa kana MiddleNode yakatsanangurwa musarudzo uye inogona kuremara uchishandisa CircuitPadding sarudzo.
Wakawedzera rutsigiro rwechokwadi SENDME maseru kudzivirira kubva pakurwiswa kweDoS zvichibva pamutoro apo mutengi anokumbira kurodha pasi mafaera mahombe uye inomira kuverenga mashandiro mushure mekutumira zvikumbiro, asi ichienderera ichitumira SENDME yekuraira mirairo iyo inoraira yekuisa node kuenderera kuendesa data.
Imwe neimwe SENDME sero ikozvino inosanganisira traffic hash, iyo inosimbisa uye iyo yekupedzisira node, pakugamuchira iyo SENDME sero, inogona kuona kuti rimwe divi ratogamuchira traffic inotumirwa nekugadzirisa maseru akapfuura.
Icho chimiro chinosanganisira kuiswa kweyakajairika subsystem yekutumira mameseji muye muparidzi-anonyorera maitiro, ayo anogona kushandiswa kuronga kudyidzana mukati meiyo module.
Kuti uongorore mirairo yekudzora, yakajairika ongororo subsystem inoshandiswa pachinzvimbo chekuongorora kwakasiyana kwedata yekuisa yemirairo yega yega.
La mashandiro ekuita Izvo zvakaitwa kudzikisa mutoro pane iyo CPU. Tor ikozvino inoshandisa yekutsanya pseudo-yakasarudzika nhamba jenareta (PRNG) yehova yega yega, inoenderana nekushandiswa kweiyo AES-CTR encryption modhi uye kushandiswa kweanogadzira anovaka senge muraibhurari uye new OpenBSD arc4random () kodhi.
De dzimwe shanduko dzakaziviswa mubazi rino, tinogona kuwana:
- Zvekubuda zvidiki, iyo yakagadzirirwa jenareta ingangoita zvakapetwa ka100 kupfuura OpenSSL 1.1.1's CSPRNG.
- Zvisinei nekuti iyo nyowani PRNG inoongororwa nevatambi veTor seyakavimbika crypto, kusvika parizvino inongoshandiswa munzvimbo dzinoda kuita kwepamusoro, semuenzaniso mukodhi kuronga iyo yekuwedzera padding yekubatanidza.
- Wakawedzera "-list-modules" sarudzo yekuratidza runyorwa rweanosanganisira mamodule
- Kune yechitatu vhezheni yeyakavanzika masevhisi protocol, iyo HSFETCH rairo yakaitwa, iyo yaimbove inotsigirwa chete mune yechipiri vhezheni.
- Fixed bugs muTor yekutanga kodhi (bootstrap) uye kushanda kweyechitatu vhezheni yeakavanzika masevhisi protocol.
