WPA2-PSK - chii? Security Type WPA2-PSK

Wireless Lan kubatana zvino haagoni kunzi chinhu kubva zvavo. Zvisinei, zhinji, vanoshandisa (kunyanya varidzi Mobile mano) vari nechinetso wakadii wokudzivirira ezvinhu akashandiswa: WEP, WPA, kana WPA2-PSK. Rudzii zvigadzirwa, tinoona zvino. Zvisinei, vakawanda kuteerera vachapiwa kubhadharwa kwairi WPA2-PSK, sezvo patronage ichi ndiyo akakurumbira.

WPA2-PSK: Chii?

Toti ndangotanga: ino kuchengetedzwa ipi yomunharaunda batanidza kuti Wireless rezvebonde kwakavakirwa WI-Fi. For that no wired hurongwa hunobva samambure makadhi kuti kushandisa zvakananga kubatana nomukombiyuta Ethernet, zviri hazvishandi.

WiFi-Network kuchengeteka uchishandisa WPA2-PSK zvemichina ndiyo "akura". Kunyange dzimwe nzira yechinyakare zvinoda login uye pasiwedhi wobvunzisisa, uyewo zvinobatanidza encryption kuti vasanonoka Data mu mabiko uye yedzimudzangara, tarirai, kutaura mudukusa, zvechihwana prattle. Chikonzero.

howa kudzivirirwa

Ngatitange nepfungwa yokuti kusvikira ichangobva kupfuura yakachengeteka kudzivirira kubatana zvemichina anonzi WEP mamiriro. Rinoshandiswa kuperera kiyi ane Wireless kubatana uye chero devaysa anga mureza IEEE 802. 11i.

WiFi-Network kuchengeteka WPA2-PSK inoshanda musimboti iri rinenge chete, asi achaongorora kuti mapindiro kiyi kunoitika panguva 802. 1x chechetere. Nemamwe mashoko, hurongwa achaongorora zvose zvinobvira dzakasiyana.

Zvisinei, pane kuvatsva zvigadzirwa, rinonzi WPA2 Enterprise. Kusiyana WPA, inopa kwete chete pachako kuwana kiyi achikumbira, asiwo pamberi nharaunda Server ichipa kuwana. Pakazoti kwakadaro authentication algorithm anogona kumhanya mumitauro miviri vakawanda modes (semuenzaniso, Enterprise uye PSK, saka ndine zvaisanganisira AES CCMP encryption pamwero).

Basic kudzivirirwa uye kuchengeteka protocols

Uyewo kusiya kare, ano kuchengeteka nzira vanoshandisa chete Protocol. It TKIP (WEP kudzivirira mamiriro inobva Software update uye RC4 algorithm). Izvi zvose zvinoratidza kwekanguva chinokosha mazano nokuda kuwana pemambure.

Sezvinoratidzwa nemashoko zvinobatsira, pachakwo chaiyo algorithm kuti yakachengeteka kubatana kuti Wireless rezvebonde hakuna kupiwa. kutanga, WPA, WPA2 uye ipapo, vaisanganisa pamwe PSK (pachake anokosha mukana) uye TKIP (nezvenyama Key): Ndokusaka michina matsva dzakabudirira. Uyezve, pano waibatanidzwa encryption kuti mashoko panguva womuchato-yedzimudzangara, nhasi inonzi AES mureza.

chikare Michina

Security Type WPA2-PSK achiri ichangopfuura. Vasati ichi, sezvo pamusoro apa, tinoshandisa WEP hurongwa pachiimbwa TKIP. Protection TKIP chinhu chimwe, senzira kuwedzera zvishoma passkey. Pari zvinofungidzirwa kuti inokosha muoti kiyi kunoita kuwedzera kubva 40 matomu kusvika 128 matomu. With izvi zvose, unogona zvakare rokuchinja chimwe WEP inokosha dzakasiyana vanowanika uye akatuma rwoga kubudikidza Server, generating mukomana aishandisa authentication pa Login.

Mukuwedzera, hurongwa kunosanganisira kushandisa imwe zvacho pakati inokosha kuparadzira, uyewo nzira yavangabata vanonzi dambudziko predictability. Nemamwe mashoko, kana Somuenzaniso, nokuda Wireless rezvebonde kuti anoshandisa dziviriro WPA2-PSK, mumwe pasiwedhi raanotaura sezvo mufananidzo "123456789" urongwa, hazvina kuoma zvokufungidzira kuti zvakafanana zvirongwa, kiyi emagetsi uye mavara echivande, anowanzonzi KeyGen kana zvakadaro, pamunopinda ina digits vokutanga vanogona kungoerekana vaunze mana anotevera. Pano, sezvo vachiti, havafaniri kuva chete zvokufungidzira zvaimirirwa vakashandisa kutevedzana. Asi zvichida nechekare kunzwisiswa, nyore muenzaniso.

Kana musi kuberekwa inodzidzisa ari pasiwedhi, haina kukurukurwa. You nyore zvinogona dzaona aaisitaura kunyoresa Data munzanga network. Pachavo Numeric mavara echivande kwakadai zvachose wokusavimbika. Zviri nani kushandisa, pamwe chete nenhamba, tsamba, uye zviratidzo (kunyange zvichiita nonprinting inopiwa bhuku anofambidzana "inopisa" makiyi) uye nzvimbo. Zvisinei, kunyange izvi, cracking walnut WPA2-PSK anogona kutakura. Pano zvakafanira kutsanangura nzira kushanda wegadziriro.

Typical Access Algorithm

Mashoko Zvino mashomanana pamusoro WPA2-PSK System. Ko panyaya kushanda? Ndicho wemishonga vakawanda algorithms, saka kutaura, ari uchishandisa muoti. Ngationei kujekesa zvinhu pamwe muenzaniso.

Zvakanakisa, kutevedzana kuurayiwa neiyi nzira yokuchengetedza kubatana uye encryption mashoko zvitange kana akagamuchira iri sezvinotevera:

WPA2-PSK (WPA-PSK) + TKIP + AES.

Panyaya iyi, pano mukuru basa reDare vaiita kiyi (PSK) ndiko 8 kusvika 63 vatambi. In worudzii kutevedzana algorithms (kana encryption kunoitika pakutanga, kana pashure kuchinjwa, kana ari mubishi kwokushandisa anongoitika anokosha intermediates, uye zvichingodaro. D.) Ichaita kubatanidzwa, hazvina basa.

Asi kunyange pamberi kuchengeteka uye encryption gadziriro iri pamwero AES 256 (kureva ikakuruma encryption kiyi) kugura WPA2-PSK nokuda hackers, nomazvo munhau iyi, richava basa, kunyange zvakaoma, asi zvinoita.

munjodzi

Kare muna 2008, panguva musangano wakaitwa PacSec chaipiwa imwe nzira inoita kuti Hack munhu Wireless kubatana uye verenga mashoko chinopfuudzwa kubva router kusvika yeGmail.END_STRONG inouraya. Zvakatora anenge 12-15 maminitsi. Zvisinei, hadzisi postback (Client Router) uye akakundikana.

Chokwadi ndechokuti kana QoS router muoti, haugoni chete kuverenga mashoko zvitange, asi kuritsiva nemazita Kunyepa. Muna 2009, masayendisiti vokuJapan kwakamutsa zvigadzirwa kuti anobvumira kuti kuderedza nguva imwe miniti kumbozorora. Uye muna 2010 paiva ruzivo pamusoro Web ndechokuti nyore nzira kumedura kupinda module 196 Hole ndiripo WPA2, uchishandisa kiyi yayo private.

About chero chipingaidzo ari vanowanika kiyi havasi kutaura. First Yaunoti duramashoko kurwisa, pamwe chete "ndakafanana-simba", uye ipapo tarisa Wireless nzvimbo gamha omumasherufu vari zvitange uye kwavakazoita yakarekodwa. Zvakakwana inodzidzisa kuti akwirwe, sezvizvi zvaitika deauthorize kuvhura kwokutanga hutachiwana packet (kugwinha maoko). Pashure paizvozvo, kunyange kuwana munharaunda huru kuwana pfungwa kunodiwa. Unogona chinyararire kushanda is nzira. Zvisinei, kuti aite zvose zviito izvi tichada Software chaiyo.

How kutsemuka WPA2-PSK?

Nezvikonzero pachena, pane algorithm wakakwana vaityora kubatana haringapiwi nokuti rinogona kushandiswa senzira mhando anoperekedza chiito. Nyanya chete huru, uye ipapo - chete zvavo nemashoko.

Kazhinji, vane mbune kuti router inogona dzikwanise inonzi Airmon-Ng nzira nokuda club motokari (airmon-kumar kutanga wlan0 - renaming munhu Wireless adapteri). Zvadaro, kupambwa uye Kuda kutamba kuitika pamwe murayiro motokari airdump-kumar mon0 (date mugero club bhikoni zvazvingava, nokukurumidza uye encryption nzira, uwandu zvitange mashoko uye zvichingodaro. D.).

Uyezve kusashanda murayiro yasarudzwa Kuda kutamba mugero, pakwakanga murayiro ndiye chiyamuro Aireplay-Ng Deauth pamwe kuyeuka tsika (hazvina kuratidzwa pamusana ukoshi tishandise nzira dzakadaro).

Pashure (kana inodzidzisa yakatotanga vakapfuura authentication apo unobatanidza) inodzidzisa anogona kungoti patsanura kubva pemambure. Muchiitiko chino, apo kuzodzosera kupinda kubva kurutivi hacks mugadziriro kudzokorora mazano nemvumo, pashure pacho pachava zvinobvira kunomisa mavara echivande zvose. Next ipapo hwindo ne "nemaoko» (kugwinha maoko). Unogona kushandisa kushanda rinokosha WPAcrack faira kuti zvichaita kutsemuka chero password. Sezvingatarisirwa, sezvazvakaita pakutanga-kumusoro, uye hapana paaiudza munhu kwete. Tinoona chete kuti kuvapo vamwe ruzivo yose muitiro zvinoda kubva maminitsi akawanda kuti mazuva anoverengeka. Somuenzaniso, Intel pamwero processor kushanda panguva aizviti wachi kakawanda 2,8 GHz, anokwanisa kubata hapana anopfuura 500 mavara echivande por yechipiri, kana mamiriyoni 1,8 paawa. Kazhinji, zviri pachena, hatifaniri kutsausa pachedu.

panzvimbo imwe epilogue

Ndizvo zvose kuti anouya WPA2-PSK. Chii, zvichida, kuverenga rokutanga zvakajeka uye haachazovipo. Kunyange zvakadaro, nheyo date kudzivirirwa uye encryption mugadziriro kushandiswa, ndinofunga, kunzwisisa munhu. Uyezve, nhasi, vakasangana pamwe ichi zvinenge varidzi vose Mobile midziyo. Ever akacherechedza kuti kana ukaronga kubatana itsva chete vakachenjera runhare hurongwa anoda kushandisa imwe mhando kuchengeteka (WPA2-PSK)? Vanhu vazhinji havambokwanisi kuriteerera, asi pasina. In akura pazviruva unogona kushandisa vazhinji zvimwe parameters kuitira kuvandudza kuchengeteka.
