Ongororo Yechigadzirwa
Musarudzo, kadhi revavhoti humbowo hwekuti muvhoti ndiani, zvichiratidza kuti muvhoti akanyoreswa zviri pamutemo panguva yekunyoresa kuvhota, uye muvhoti ane chinangwa chekupinda musarudzo.Kadhi revhoti rinoita basa rakakosha mukuvimbisa “munhu mumwe vhoti imwe chete” uye kuona kuti sarudzo dzakachena.Ndiyo huru yeindasitiri kushandisa michina yekuverengera yemagetsi uye smart card ine kuchengetedzwa kwepamusoro, zviri nyore kuverenga nekunyora kutsiva kuzivikanwa kwevavhoti kwechinyakare mukuita kwesarudzo.
Iine IC kadhi tekinoroji seyo musimboti uye komputa uye yekutaurirana tekinoroji senzira, smart kadhi inobatanidza zvivakwa mukati mechivako chakangwara kuita organic yakazara.Iyo IC kadhi inogona kushandiswa seyakajairika kiyi uye inogona kuita mari yekugadzirisa uye kupinda, pamwe nemamwe mabasa ekutonga, sekuvhura musuwo nekadhi, yekudyira, kutenga, varaidzo, musangano, kupaka, patrol, hofisi, kuchaja sevhisi. nekadhi.
Smart makadhi anogona kukamurwa kuita super smart makadhi, CPU makadhi uye memori makadhi.Zvinoenderana nekuverenga nekunyora modhi yesmart kadhi, inogona kukamurwa kuita yekubata IC kadhi uye isina contact IC kadhi.Iyo tekinoroji yekuchengetedza yechip uye COS inopa mbiri yekuchengetedza vimbiso yeCPU kadhi.Iyo CPU kadhi ine yayo inoshanda sisitimu ine zvakaderera zvinodiwa zvekombuta network system uye inogona kushandwa kunze kwenyika.Iyo memori kadhi inofanirwa kushandiswa munzvimbo yakakwana yetiweki.Iyo chaiyo-kadhi-yakawanda-application inogona kuitika, uye yega application yakazvimirira yega uye inodzorwa neyayo kiyi manejimendi system.Iine basa rekusimbisa zvitupa, izvo zvinogona kuratidza kuzivikanwa zviri pamutemo kwemuridzi wemakadhi, chiteshi chemakadhi, uye kadhi.Inogonawo kushandiswa sechishandiso chekubhadhara uye chekugadzirisa kudzivirira kukanganisa kwekutakura mari yakawanda uye shanduko, kuitira kuti uvandudze kushanda kwekutengeserana.Panguva imwecheteyo, yakashongedzerwa neyekuchengetedza module, iyo inoshandisa kiyi inoenderana kuti iwane encryption, decryption uye transaction process, kuitira kuti upedze kuvimbiswa kwekuchengetedza nekadhi remushandisi.Inogonawo kushandiswa semutakuri wedata, uye iyo CPU kadhi inogona kushandiswa seyakachengeteka mutakuri wemafaira emunhu kana data rakakosha, uye iyo data inogona kuchengetedzwa kweanenge makore gumi.
Nekushandisa kuverenga kwemagetsi, tinogona kupa marudzi akasiyana emakadhi esarudzo akangwara ane akasiyana maprotocol, akasiyana ekuchengetedza uye akasiyana mazinga ezvitupa zvekuchengetedza, uye isu tinogona zvakare kushandisa evagari makadhi echitupa akangwara evavhoti kuti vazivikanwe.Tinogona kupa zvizere-maitiro masevhisi ekushandisa makadhi esarudzo, anosanganisira kugadzira chip, kurongedza, system-on-chip (SoC) kugadzirisa, kurongedza application, yakasarudzika kadhi kadhi, anti-yekunyepedzera kudhinda, yakasarudzika data kunyora, sarudzo system yekubatanidza, nezvimwe. Kadhi rakangwara rakapihwa rinosangana nezviyero zvepasi rose.Semuenzaniso, kutaurirana protocol kunoenderana ne ISO7816, ISO14443 uye mamwe mazinga, uye chengetedzo chip inoenderana neCC EAL4, EAL5 chitupa.Inotsigirawo kudzokorora kuverenga nekunyora, uye inogona kushandisa zvakatipoteredza-inoshamwaridzika PET zvinhu nekupfeka kuramba, corrosion kuramba uye hupenyu hwebasa hweanopfuura makore gumi.
Kushandiswa kwemakadhi esarudzo musarudzo kunogona kuzadzikisa chinangwa chekupa makadhi kamwe chete uye kushanda kwenguva yakareba, izvo zvinoreva kuti vavhoti vanokwanisa kushandisa makadhi acho kunyoresa vavhoti uye kuvhota musarudzo imwe neimwe.
