ATECC608: tsarin tsaro don Rasberi Pi

ATECC608 Rasberi Pi

da Ayyukan IoT Suna daɗa shahara sosai tsakanin masu yin da ƙwararru waɗanda suka dogara da allon ci gaba kamar Arduino ko nasu SBC Rasberi Pi. Tsaro a cikin waɗannan ayyukan shine maɓalli, tunda ana iya kai musu hari ta nesa ko canza ayyukansu idan akwai rauni. Wannan shine damuwar da ATECC608 ke zuwa don warwarewa.

Har zuwa yanzu akwai matakan da abubuwa da yawa don ƙirƙirar ayyukan kowane nau'i, amma ƙanƙan da gaske suke don ƙarfafa tsaro har sai wannan ɓangaren kamfanin Microchip, Shahararren mai haɓaka samfuran kamfani na PIC microcontrollers.

Game da ATECC608

Saukewa: ATTEC608

Wannan aikin Saukewa: ATECC608 Yana ba ka damar ƙara chiparfin tsaro na Microchip a cikin Rasberi Pi, don haka zai iya kare ƙirarka ta IoT daga harin jiki da na nesa. Kari akan haka, rukunin kadan ne, kuma yana da sauki hade da Rasbperry Pi, ban da samun farashin $ 10 kawai.

ATECC608 yana da kyau mai sauki don amfani, kawai kuna da haɗa shi zuwa Rasberi Pi yana bin jagorar sauri wanda zaku samu a cikin wannan Adireshin GitHub. Bayan haka, yana shirye don amfani tare da misalan Python akan GitHub ta Microchip za ku samu a cikin wannan mahaɗin. Kuma idan kuna mamakin ƙirarta, tushen buɗewa ne (CERN OHL v1.2).

Ga waɗanda basu sani ba, CERN OHL ko Open Hardware Lasisi lasisi ne na buɗe tushen da aka shirya don ayyukan hardware. CERN ne ya kirkireshi kuma an buga sigar iri daya, kamar wannan v1.2 wanda shine na karshe daya bita a shekara ta 2013.

Duk an tsara su da fasahar Microchip, amma an tsara su ta Kamfanin Faransa mgit. a kuma an kirkireshi ne ta hanyar OTS Security.

La ra'ayin shine ya fara zama sananne don kare ayyukan IoT tare da Rasberi Pi, don amfani da haɗin haɗi tare da TLS, anti-cloning, PKCS11 Token, da dai sauransu.
