Ngaahi fakahinohino kuo ʻoatu ki he kouti ʻo Siava mo e C, lea ʻi he telinga, vave ʻene hoko ʻi he malohi maʻulalo mo ha ʻiuniti pule fakamamani lahi ʻoku kau ʻi he ngaahi fakalakalaka lahi kehe ʻoku tanaki atu ki he ngaahi fale ʻiloa 80C51. ʻOku ʻomi ʻe he sitepu ki hono feʻaveʻaki ʻo e tekinolosia mei he 0.18 μm ki he 5-ukamea 0.14 μm CMOS e tekinolosia ha ngaahi lelei lahi ange ʻi he ngaahi meʻa fakamaluʻi, ngaahi maʻuʻanga tokoni ki he manatu, crypto ʻa e fikaʻi ʻo e fikaʻi ʻo e RSA mo e ECC pea pehe ki he lava ke maʻu ha tokoni ki he ngaahi meʻangaue ki he 2-ki mo e 3-ki he naunau fakaʻilekitulonika encryption tuʻunga moʻui (TI) mo e tuʻunga encryption fakalakalaka (AES) ngaahi ngāué.
ʻE lava ke maʻu ʻa e interface fetuʻutaki, ʻOku hanga ʻe he contactless Interface mo e S2C ʻoku fili ʻo ʻai ke faingofua hono fakahoko ʻo e ngaahi meʻa tuʻufonua pe fakaava mo e ngaahi founga ngaue fakavahaʻa-taʻu ʻi he ngaahi konga ʻo e maketi hange ko e fakapangike, ʻI-paasipooti, ʻU kaati ID, Kaati moʻui lelei, hu malu, ʻU kaati Siava, Ofi ki he fetuʻutaki ʻi he malaʻe (NFC) connectable e nima toʻotoʻo pea pehe ki he falalaʻanga ʻeni (TPM).
Ngaahi folofola ʻe tolu-TI coprocessor
ʻOku poupouʻi ʻa e TI ʻoku fakaʻaongaʻi ki he symmetric encryption ʻe ha fakatapui, ngaue maʻolunga, ngaahi meʻangaue ʻoku ne fakafepakiʻi lahi coprocessor. Tokotaha teʻeki mali ti mo e tolu-TI, makatuʻunga ʻi ha ki ʻe ua pe tolu, ʻe lava ke tamateʻi ʻi loto ʻi he 40 μs. Ngaahi tuʻunga moʻui mahuʻinga (ISO/IEC, ANSI, FISAME) mo e Kouti fakapapauʻi ʻo e popoaki (MAC) ʻoku poupouʻi kakato. ʻOku lava ke maʻu atu ha konga crypto ʻo e Laipeli malu ki he TI.
AES coprocessor
Ko e SmartMX ko e fuofua kaati poto microcontroller ia ke ne ʻomi ha ngaue maʻolunga kuo fakatapui 128-kiʻi ngaue ʻoku faitatau mo e ngaue ke poupouʻi ʻa e ngaahi meʻa ʻoku maʻu. ʻOku makatuʻunga hono fakahoko ʻi he FIPS197 ʻo hange ko hono fakaleleiʻi ʻe he ʻinisititiuti fakafonua ki he ngaahi tuʻunga moʻui mo e tekinolosia (NIST), pea ʻoku ne poupouʻi ʻa e loloa ʻo e 128, 192-kiʻi, and256-lahi ʻo e ngaahi tuʻunga ʻo e ngaue ʻoku faitatau mo TI. Ko e ngaahi meʻa ʻoku hoko ko e toʻu tangata hoko ki symmetric fakamatala encryption mo fokotuʻu atu ha fetongi ki he TI ʻoku ne ʻomi ha tuʻunga malu lahi ange. ʻOku lava ke maʻu atu ha konga crypto malu ʻo e Laipeli ki he ngaahi meʻa ʻoku ʻikai ke maʻu.
Ngaahi fotunga maluʻi
ʻOku kau ʻi he SmartMX ʻa e ngaahi meʻa maluʻi kehekehe mo e OS ʻo hange ko e countermeasure ki he faʻahinga ʻohofi kotoa pe. NXP Semiconductors fakaʻaongaʻi ʻenau ʻilo lahi ki he maluʻi ʻo e ngaahi pinati, fakatahaʻi mo e tekinolosia ʻo e handshaking, 0.14 μm tekinolosia matolu ʻaupito, kuluuʻi ʻa e fakaʻuhinga mo e shielding founga ki he ngaahi ola lelei ʻi CC EAL5 +, EMVCo mo e faʻahi tolu kehe certifications mo e ngaahi fakangofua.
SmartMX ʻiuniti pule ʻo e manatu (MMU), fokotuʻutuʻu ke fakaʻuhingaʻi ha ngaahi konga kehekehe ʻo e manatu pea vahe ʻa e ngaahi ʻulungaanga maluʻi ʻo fakatatau ki, poupouʻi ha foʻi fakakaukau malohi ʻoku ne taʻofi ʻa e ngaahi founga kehekehe ʻo e fakaʻaongaʻi. Ko e founga pe ʻo e System ʻoku ne maʻu kakato ʻa e ngaahi faingamalie ki he feituʻu kotoa pe ʻo e manatu mo e ngaahi meʻa ʻoku ʻi ai e ngaahi meʻa ʻoku ʻikai ke nau manatuʻi, ʻi he founga ngaue ʻoku fakangatangata pe ʻa e ngaahi faingamalie. ʻOku configurable ʻa e ngaahi fakangatangata ʻo e founga ngaue ʻi he polokalama fakakomipiuta ʻoku lele ʻi he System Mode.
ʻOku fakahaaʻi ʻa e ngaahi meʻa maluʻi SmartMX ko e maʻu ha ngaahi koloa makehe ʻe he kau kasitoma NXP Semiconductors. ʻOku lau ʻa e countermeasures ki he ngaahi ʻohofi ʻo e mama ko e "lelei taha ʻi he kalasi".
Fakafuofuaʻi ʻo e maluʻi mo e ngaahi tohi fakamoʻoni
ʻOku maʻu ʻa e tohi fakamoʻoni maluʻi ʻo e koloa ʻo fakatatau mo CC EAL5 +. ʻIkai ngata ai, fakangofua faʻahi tolu hange ko e EMVCo (VISA, LI), ZKA mo ha niʻihi kehe, ʻo fakatatau mo e ngaahi fie maʻu ki hono fakaʻaongaʻi, ʻoku lava ke maʻu.
