Ba tare da tuntuɓar IC katin RF katin - Philips Mifare daya katin (M1 katin) S50 S70 gabatarwa

I. Bayani
Philips ta Mifare Daya ba tare da tuntuɓar IC katin da aka sani da RF IC katin, M1 katin, shi ne nasarar haɗuwa da RF ganewa fasaha da kuma IC katin fasaha, warware matsalar da ba a yi aiki (babu wutar lantarki a katin) da kuma ba tare da tuntuɓar, shi ne babban ci gaba a fannin na'urorin lantarki.
1, High aminci
Babu lamba ta inji tsakanin katin IC mara lamba da mai karatu, yana guje wa kuskure daban-daban saboda karatu da rubutu na lamba. Bugu da ƙari, ba tare da lamba katin farfajiyar babu tsirara guntu, babu damuwa game da guntu fadowa, static karya, lankwasa lalacewa da sauran batutuwa, duka sauki katin bugawa, kuma inganta amfani da katin aminci.
2, Easy aiki da sauri
Saboda sadarwa mara lamba, mai karatu zai iya aiki a kan katin a cikin kewayon 15cm, don haka ba dole ba ne a saka katin, yana da sauƙin amfani ga mai amfani.
Ba tare da shugabanci ba lokacin amfani da katin mara tuntuɓar, katin zai iya karanta marubucin farfajiyar kowane shugabanci don kammala aiki, wanda ya haɓaka gudun kowane amfani.
3. Kula da rikici
Akwai hanyoyin hana rikici masu sauri a cikin katin da ba a tuntuɓar shi ba, wanda ke hana tsoma baki tsakanin katin, don haka mai karatu zai iya sarrafa katin IC masu yawa a lokaci guda. Wannan yana haɓaka daidaito na aikace-aikace, haɓaka saurin aikin tsarin a hankali.
4, iya dacewa da daban-daban aikace-aikace
Kayan tsarin ajiya na katin mara tuntuɓar yana sa ya zama katin mai amfani da yawa, ana iya amfani da shi ga tsarin daban-daban, mai amfani zai iya saita kalmomin sirri daban-daban da yanayin samun dama dangane da aikace-aikace daban-daban.
5, kyakkyawan aikin ɓoyewa
Serial lambar katin ba tare da tuntuɓar ba ne na musamman, masana'antun sun karfafa wannan lambar jerin kafin samfurin ya fita daga masana'antar, ba za a iya canzawa ba. Tsakanin katin mara tuntuɓi da mai karatu yana amfani da tsarin tabbatarwa na biyu, watau mai karatu yana tabbatar da halattar katin IC, yayin da katin IC yana tabbatar da halattar mai karatu.
Katunan ba tare da tuntuɓar ba dole ne a tabbatar da juna sau uku tare da mai karatu kafin sarrafawa, kuma duk bayanan an ɓoye su yayin sadarwa. Bugu da ƙari, kowane bangare na katin suna da yanayin samun damar kalmar sirri na aiki.

2. M1 tsarin sigogi
Ba tare da tuntuɓar IC katin M1 katin bayanai ajiya lokaci ne shekaru 10, za a iya sake rubuta sau 100,000, karanta Unlimited sau. Katin M1 ba tare da wutar lantarki ba, yana da eriya, wanda ya ƙunshi kewayon ma'ana na sarrafawa da kewayon ma'ana na sadarwa, sadarwa tsakanin katin da mai karatu yana amfani da tsarin tsare sirri na DES da RES na duniya, tare da babban aikin sirri.

3. Ka'idar aiki
Yankin lantarki na katin ya ƙunshi eriya guda ɗaya da ASIC, babu wasu na'urorin waje.
eriya: eriya na katin ne da dama sets na coils da aka kewaye, da kuma dace da kunshe a cikin katin ISO.
ASIC: ASIC na katin ya ƙunshi babban saurin (106KB bandwidth), na'urar sarrafawa da kuma 8K bit EEPROM.
M1 RF katin aiki ka'ida ne: karatu zuwa M1 katin aika da wani set na m mita na lantarki magnetic waves, katin yana da wani LC jerin resonance kewaye, da mita da karatu fitar da mita iri daya, a karkashin karfafa na lantarki magnetic waves, LC resonance kewaye samar da resonance, don haka sa a cikin Capacitive da lantarki caji, a wani karshen wannan Capacitive, sai da wani gudanar da lantarki famfo, aika da kaya a cikin Capacitive zuwa wani Capacitive ajiya, lokacin da tara kaya ya kai 2V, wannan Capacitive za a iya yi a matsayin ikon samar da aiki ƙarfin lantarki ga sauran kewaye, fitar da bayanai a cikin katin ko karɓar karatu data.

IV. Sirri
Sirrin M1 katin RF yana da kyau saboda: tabbatarwa uku kafin karantawa da rubutu, lambar jerin katin na musamman, ɓoye-ɓoye na bayanai na watsawa, kalmar sirri ta watsawa da kuma kare kalmar sirri ta damar shiga.
Kalmar sirri a katin tana da kariya, ba za a iya karantawa ba, kuma kawai masu amfani da suka san kalmar sirri za su iya gyara shi. Kayan ajiya na EEPROM a katin ya bambanta zuwa bangarori 16, kowane bangare yana da kalmar sirri mai damar shiga, mai amfani zai iya saita kalmar sirri daban-daban dangane da aikace-aikace daban-daban na bangare (amfani da katin ɗaya). Kalmomin sirri na samun damar bangaren an raba su zuwa rukunin kalmomin sirri daban-daban na KEY A da KEY B, don samun damar ƙwaƙwalwar ajiya ne kawai bayan tabbatar da KEY A ko KEY B dangane da yanayin samun damar.
Kodayake yanzu akwai fasahar fashewa ta fashewa ta Mifare One, duk da haka, idan aka yi maɓallin tsarin tsarin tsarin tsarin tsarin tsarin tsarin tsarin tsarin tsarin tsarin tsarin tsarin tsarin tsarin tsarin tsarin tsarin tsarin tsarin tsarin tsarin tsarin tsarin tsarin tsarin tsarin tsarin.

5. ajiya yankin
An rarraba 8K bit EEPROM na katin M1 zuwa bangarori 16, kowane bangare ya ƙunshi 4 bangarori da 16 bytes a kowane bangare.
Block 3 (watau na huɗu block) na kowane bangare yana ƙunshe da kalmar sirri A (6 bytes), sarrafa damar (4 bytes), da kalmar sirri B (6 bytes) na wannan bangare, wani bangare ne na musamman kuma sauran bangare uku sune bangaren bayanai na gaba ɗaya. Duk da haka, block 0 na bangare 0 ne na musamman, wanda aka yi amfani da shi don adana lambar masana'antun, wanda ya riga ya karfafa, ba za a iya canzawa ba, wanda ake kira "block 0".
1, lamba IC katin ne wani irin katin da ya bayyana kusan shekaru goma bayan katin maginadisu. Yana haɗa duk bayanai sarrafawa sassa, ciki har da kalmar sirri tabbatarwa da ajiya da kuma ayyuka a kan wani kananan silicon chip, sanya a katin girman katin maginadis, musayar bayanai ta hanyar da dama lamba katin da kuma mai karatu kewayawa.
Touch IC katin shawo kan rashin amfani kamar Magnetic katin aminci da rashin tsaro. Amma har yanzu akwai rashin amfani:
1) katin lamba na IC katin, tsirara a kan farfajiyar IC katin, a wasu lokuta (kamar karkata, lalacewa, da dai sauransu) sa IC katin lalacewa ko karatu da rubutu kuskure ya faru.
2) katin zama na mai karatu da rubutu saboda gurɓataccen gurɓataccen gurɓataccen gurɓataccen katin, shigar da kayan waje na katin, da sauran dalilai, ya sa mai karatu ya lalace ko ba zai iya aiki yadda ya kamata ba, yana buƙatar kulawa sau da yawa.
3) Saboda a lokacin amfani, katin da katin wurin aiki ne directional, a lokacin amfani, saboda katin wurin aiki ne mai ƙuntatawa, yana da wuya a saka katin IC. Amfani da lamba IC katin ne sosai m.
4) Duk da cewa akwai wasu matakan sirri a kan katin IC, tsaro na sirri na katin IC ya rage saboda universality na mai karatu.
5) Ko da lamba IC katin a halin da ake amfani da al'ada, sa ma'amala tsari na dogon lokaci, tsawaita fasinja tafiya lokaci da kuma motoci juyawa, sa kamfanin saka hannun jari mafi karfin aiki, kara aiki kudin.

6. Babban fasali na katin IC mai lamba:
1) Non-inji tuntuɓar tsakanin katin da mai karatu.
2) katin surface babu tsirara na'ura, ba zai lalata IC katin saboda lalacewa, lankwasawa. Katin kanta ne inactive sassa, karamin girma, m da abin dogaro.
3) Mai karatu ba ya buƙatar katin matsayi, za a iya rufe shi gaba ɗaya a cikin akwatin.
4) No directionality lokacin amfani, katin za a iya fadi a kan karatu surface a kowane shugabanci, za a iya kammala
Karanta da rubuta aiki.
5) Karatu da rubutun sadarwa tare da katin IC ta hanyar eriya.
6) Mai karatu da kuma rubutu tare da katin IC aiwatar da tsarin ganewar kalmar sirri ta hanyar biyu. Mai karatu zai iya gane halal IC katin
Jima'i, katin IC zai iya gane shi "master" (mai karatu), ya gane "master" karatu da rubutu damar.
7) Bayar da katin IC mara tuntuɓi bisa ga takamaiman ka'idoji - saboda alamun da ba za a iya canzawa ba (wanda ke nuna masana'antun, lambar lasisi mai amfani da takardun shaida), a bayyane matakin gudanarwa. Kuma tare da duk masu karatu da katin IC dole ne a fara da kuma ayyana damar samun damar ta hanyar katin MASTER wanda kawai mai wallafawa ke da shi.
8) MIFARE 1 nau'in katin IC mara tuntuɓi yana da ƙarfin 8K bit, yana da sassa 16, yana tallafawa aikace-aikace daban-daban, adana bayanai na shekaru 100, yana iya sake rubuta sau 100,000, karantawa mara iyaka, katin ba tare da wutar lantarki ba, yana da eriya, yana ƙunshe da kewayon ma'ana na sarrafa ɓoye-ɓoye, sadarwa tsakanin katin da mai karatu tana amfani da tsarin tsare-tsaren tsare-tsaren tsare-tsaren tsare-tsaren tsare-tsaren tsare-tsaren tsare-tsaren
