NXP MIFARE DESFire EV3 IC ke sehlahisoa se ntlafalitsoeng sa DESFire, phetisetso ea boraro ea lihlahisoa tsa MIFARE DESFire tse se nang mabitso, mme e hlahisa lintlafatso tse ngata tsa ts'ebetso ho ts'ehetsa lits'ebetso tse ngata tse fapaneng tse bohlale tsa toropo. DESFire EV3 chip e na le melemo e mengata, joalo ka mefuta e mengata ea ho skena ho feta ea pele ho eona, lebelo la transaction e potlakileng le ho tsamaellana morao le lihlahisoa tse fetileng tsa MIFARE DESFire. Likopo tse ka bang teng li kenyelletsa ho paka makoloi, taolo ya phihlello le dipalangwang tsa setjhaba, e ka sebelisoang ho likarete tse bohlale tsa setso kapa lisebelisoa tsa mohala. Likarolo tsa ts'ireletso tsa IC li thusa ho thibela bosholu le bosholu.
EV3 IC e tla lumellana le ts'ebeletso ea leru ea MIFARE 2GO, ho bolelang hore likhoebo li tla khona ho e sebelisa ho nolofalletsa lits'ebetso tse bohlale tsa toropo sesebelisoa sefe kapa sefe se kentsoeng ke NFC. Ntle le lisebelisoa tse aparoang, e boetse e kenyelletsa lifono tse bohlale.
Lelapa la sehlahisoa sa MIFARE DESFire le ipapisitse le maemo a bulehileng a lefats'e bakeng sa li-interface tsa RF le mekhoa ea encryption, ho fana ka li-ics tse thehiloeng ho microcontroller tse sireletsehileng haholo. Lebitso DESFire le bolela hore DES, 2K3DES, 3K3DES le lienjineri tsa encryption tsa AES li sebelisoa ho sireletsa data e fetisoang.
Letoto lena le loketse haholo bakeng sa baetsi ba tharollo le basebelisi ba sistimi ho aha ba tšepahalang, tšebelisano 'moho le scalable contactless tharollo. Sehlahisoa sa MIFARE DESFire se ka kopanngoa ka mokhoa o se nang moeli ho tharollo ea selefouno, mme e tshehetsa kananelo ya boitsebiso, taolo ya phihlello, likopo tsa botšepehi le micropayment, hammoho le litharollo tsa likarete tse bohlale tsa lisebelisoa tse ngata molemong oa ho kenya litekete tsa lipalangoang.
Hardware le software ea IC e tšehetsa algorithm e bulehileng ea encryption mme e fetile Mekhoa e Tloaelehileng ea EAL 5+ setifikeiti se tloaelehileng. E boetse e na le nako ea transaction ho ntlafatsa ts'ireletso, 'me e sebelisa NFC e sireletsehileng le e ikhethang(LETSATSI) tshebetso ya melaetsa, e hlahisang molaetsa o ikhethang oa netefatso bakeng sa ho penya ka 'ngoe, ebe o romela molaetsa ho seva bakeng sa netefatso ho thibela cloning.
