Lapho izihlahla ziphakeme kancane, utshani buluhlaza, ilanga likhanya, futhi ngifunda esikhungweni semfundo, nginekhadi lezenhlalakahle labafundi. Ngangiyithanda ngenxa yokusebenza kwayo nokucabangela, kodwa, njengazo zonke izinto ezinhle, isikhathi sayo sokufaneleka siphelelwe yisikhathi futhi kwadingeka ngikhohlwe ngalesi sibusiso sempucuko yaseMoscow isikhathi esingapheli. Ithathelwe indawo yi-Troika, ekwazile ukumunca izinzuzo ze-SCS, kodwa hhayi zonke...
I-Troika + inqubomgomo yomshwalense wezokwelapha oyimpoqo =? noma ukuthi konke kwaqala kanjani
Konke kwaqala lapho ngigula futhi ngithola ukuthi ngangilahlekelwe yikhadi lami lomshwalense wezokwelapha eliyimpoqo. Naphezu kweqiniso lokuthi ngangikhumbula inombolo ngekhanda, ngangidinga okuthile okungaxhunywa ekhadini lolwazi eliluhlaza emtholampilo, ngaphandle kwalokho ngangingeke ngikwazi ukwenza i-aphoyintimenti nodokotela futhi ngithole ikhefu elisemthethweni lokugula. Kwakunezinketho eziningi: buyisela inqubomgomo (ukuze kamuva ukwazi ukuthola endala ekuhlanzeni kokuqala); khiqiza futhi uphrinte ibhakhodi yenqubomgomo (ibhakhodi esiqeshini sephepha ayinasithunzi), noma thatha ikhadi lakho lokuxhumana nabantu elidala... Ngaxazulula le nketho yokugcina. Ukunemba kakhudlwana, nganquma ukungagxili kukho, kodwa ukubhala phansi inqubomgomo yami njengabathathu ngendlela efanayo njengoba kubhalwe ekhadini lezenhlalo le-Muscovite.
Ukulungisa i-Troika
Ngokwazi amakhono e-Mifare Classic - amakhadi ahambisanayo, nganquma ukuhlanganisa i-Troika nekhadi lomfundi elidala ukuze kube lula futhi ngenxa yesithakazelo kumphumela wokuhlolwa.
Njengoba sazi, amakhadi e-Mifare Classic 1K nawe-4K akhishiwe ekusebenzeni ngenxa yokuba sengozini ukuze kuvikeleke kakhudlwana kodwa ehambisanayo i-Mifare Plus S, i-Plus X 2k noma i-Plus EV1 2k. Kodwa ingqikithi ihlala ifana: kokubili amakhadi omphakathi kanye ne-Troika anokugcwalisa okufanayo, umehluko kuphela umthamo (inani lemikhakha evikelekile, okuyinto kithi ayinandaba nhlobo).
Ngihlome ngezindatshana ezimayelana nocwaningo ngokuvikeleka kwe-Troika kanye nohlelo lokusebenza lwe-Android “Ithuluzi Le-Mifare Classic,” nginqume ukuqale ngibheke ngaphakathi kwekhadi lokuxhumana nabantu ukuze ngithole indawo lapho kuqoshwa khona inombolo yenqubomgomo yomshwalense wezokwelapha oyimpoqo. Sibonga u Bengivele ngicabange ukuthi kuzoba emkhakheni wesi-5 wemephu, egcinwe njengohlelo lokusebenza lwezokwelapha lwe-MGFIF, oluqinisekiswe ngokusebenza.
Inombolo yenqubomgomo edingekayo ivele emkhakheni wesi-5 emugqeni wesibili ukusuka kubhayithi yesi-2 ukuya ku-9, okungukuthi, kulesi simo “7700009016811218". Kuhle, kukhona umkhondo (noma kunalokho, kukhona umkhondo)!
Ngokuqondene nekhadi le-Troika, umkhakha we-5 ugcwele ama-zero, okungukuthi, awakasetshenziswa. Okhiye A no-B bahlukile kulawo aku-SCS, kodwa lokhu kuyalungiseka, bangaphinda babhalwe ngendlela efanayo neyalapho.
Izivivinyo
Ngaphezu kwenombolo yenqubomgomo yomshwalense oyimpoqo oyimpoqo, lo mkhakha ubuqukethe enye idatha, inhloso yayo engingayazi. Ngemva kokufunda ama-athikili mayelana nomkhakha we-8 (isikhwama se-electronic) nokuvikelwa kwawo ngokufaka okulingisayo, ngicabange ukuthi lapha le datha ingadlala indima efanayo nokufakwa okulingisayo noma i-checksum ukuze kuqinisekiswe ubuqotho bedatha emkhakheni. Ngakho-ke, nginqume ukuhlola lokhu ngokubhala kabusha wonke umkhakha ku-Troika eyodwa ncamashi njengaku-SKS, kanti kowesibili - inombolo yenqubomgomo kuphela. Kulula ukusho kunokwenza!
Ngithathe ukulahla okugcwele ku-SCS futhi ngabhala phansi wonke umkhakha wesi-5 ku-Troika yokuqala, futhi kwesibili ngabhala phansi ukulahlwa okuhleliwe komkhakha wesi-5, lapho kuvela khona inombolo yenqubomgomo kuphela.
Imiphumela
Ngemva kokuya emtholampilo nokubheka amakhadi womabili, ngakwazi ukuwasebenzisa womabili ukufaka emshinini wolwazi nokwenza isikhathi sokuhlangana nodokotela! Yiqiniso, kufanele ukhethe "Ikhadi Le-Muscovite" noma "Ikhadi Lomphakathi lase-Muscovite" njengendlela yokuqinisekisa (zombili izindlela ziyasebenza) bese ubeka ikhadi kumfundi.
Lokhu kulandela ukuthi imishini yolwazi idinga inombolo yenqubomgomo kuphela esikhaleni esihlinzekiwe kanye nezikhiye zomkhakha wesihlanu abazaziyo.
Manje ungamangaza izisebenzi zasemtholampilo kakhulu ngokubabonisa ukusetshenziswa kwe-Troika njengenqubomgomo yomshwalense wezokwelapha oyimpoqo futhi uthole ukuqinisekiswa okusebenziseka kalula nesimanjemanje, ngoba ngisho nemishwalense yesimanje eyimpoqo yezokwelapha ayisekeli ukushintshaniswa kolwazi ngaphandle kokuthinta - kudingeka ifakwe ne-chip ku-infomat. Futhi "i-Troika" iba ukhiye wedolobha, ikakhulukazi, emitholampilo.
Buyekeza 1: Ngesicelo sabasebenzi, ngizokutshela ukuthi ungayenza kanjani "eminwe yakho". Njengoba ngibhale ngenhla, insiza ye- "Mifare Classic Tool" ye-Android ilungele lokhu.
Okulandelayo:
1. Chofoza okuthi “Funda umaka”
2. Hlola ukuthi std.keys kanye namafayela okhiye we-extended-std.keys akhethiwe
3. Sincika kokuthathu ocingweni bese uchofoza Qala ukwenza imephu bese ufunda ithegi. Ifoni izocabanga isikhashana ngenkathi ithatha okhiye.
4. Lapho sekuqediwe, indawo yokulahla izovuleka (imephu ingasuswa ocingweni ngenkathi ihlelwa). Kuyo sinentshisekelo kunombolo yomkhakha 5. Ibukeka kanje:
00000000000000000000000000000000
00000000000000000000000000000000
00000000000000000000000000000000
FBC2793D540B7C378800D3A297DC2698
Ngezansi kukhona okhiye u-A no-B
5. Umsebenzi wethu ukuhlela lo mkhakha khona lapho futhi siwulethe kuleli fomu:
00000000000000000000000000000000
00888888888888888800000000000000
00000000000000000000000000000000
186D8C4B93F908778F029F131D8C2057
Uphi u-888... - Inombolo yakho yomshwalense wezempilo oyimpoqo. Naka ukunaka okukhethekile lapho ubhala kabusha okhiye bomkhakha: uma kukhona iphutha lokuthayipha, usengozini yokulahlekelwa ukufinyelela okuphelele noma okuyingxenye kumkhakha.
6. Chofoza isithonjana semenyu ekhoneni eliphezulu kwesokudla bese uchofoza okuthi Bhala Lahla -> BHALA UKULAHLA, khetha umkhakha wesi-5 kuphela (ungahloli okunye); namathisela ikhadi ocingweni -> qiniseka ukuthi womabili amabhokisi okuhlola aseduze kwamafayela ayisihluthulelo bese uchofoza okuthi QALA UKWENZA Imephu FUTHI UBHALA UKULAHLA. Ngemuva kwalokho, ngemuva kokulahla, kufanele sibone umlayezo "Idatha ibhalwe ngempumelelo"
Ikhadi selikulungele ukuya emtholampilo!
