Kutetezedwa kwa MCU kwa ma e-banking ndi chizindikiritso cha e-kukhudzana komanso kusayanjanitsidwa

Imatchedwa ST31P450, imamangidwa pamakina a 40nm ndipo imayang'aniridwa popanda kulumikizana ndi kulumikizana ku banki, chizindikiritso, mayendedwe ndi kulipiritsa televizioni. Ma mawonekedwe a RF akuphatikiza RF UART yopanga maulumikizidwe osagwirizana ndi 848kbit / s omwe amagwirizana ndi ISO / IEC 14443 Mtundu A, palinso mawonekedwe osinthika omwe amagwirizana ndi ISO / IEC 7816-3 (T = 0, T = 1).

Pamtima pake pali 55MHz wapawiri-msingi 32bit Arm SecurCore SC000 yomwe imakumana ndi ISO 7816 ndi ISO 14443 Type A smart-Card and standardless contact, malinga ndi ST, ndipo matembenuzidwe amapezeka kuti amathandizira ku library ya Mifare kuphatikizapo Classic, Plus ndi DESFire. SC000 imamangidwa pa Cortex M0, yokhala ndi zowonjezera zina zothandizira kuteteza motsutsana ndi adani.

"ST31P450 microcontroller otetezedwa, ndi malaibulale ena okhudzana nawo, akuyembekezeredwa kukwaniritsa Common Criteria EAL5 +, komanso EMVCo ndi CUP [China UnionPay] mkati mwa miyezi ikubwerayi," idatero kampaniyo.

450kbyte ya flash ndi 10kbyte ya nkhosa amaphatikizidwa pa-kufa ndipo mabatani azachitetezo cha Hardware amaphatikizapo mathamangitsidwe a AES a AES-128, AES-192 ndi AES256 algorithms; makina atatu ofufuzira a Triple DES accelerator (EDES +) a 'cipher block chaining' (CBC) mode, DES yachangu ndi maulendo atatu patatu kolembetsedwa ndi ma key atatu olembetsera ndi marejista amodzi amodzi; ndi NESCRYPT cryptoprocessor wofalitsa ma key a algorithm yogwira ntchito zakale mpaka 4,096bit.

Ndipo pali timitengo tating'onoting'ono tokwana 16bit ndi timer timadilesi.

Kugwiritsa ntchito kwatha -25 mpaka + 85 ° C ndi 2.7 mpaka 5.5V pamagulu olumikizana ndi ISO / IEC 14443 kutsatira.
