Kutsimikizira
Chiwonetserochi chikuwonetsa kuyenderera kwa lamulo komwe STSAFE-A110 imayikidwa pa chipangizo chomwe chimatsimikizira munthu wakutali (chochitika cha chipangizo cha IoT), wolandila wakumaloko akugwiritsidwa ntchito ngati njira yodutsa ku seva yakutali. Zomwe STSAFE-A110 imayikidwa pamphepete yomwe imatsimikizira kwa omwe ali nawo, monga kale.ample kwa masewera, zipangizo mafoni kapena consumables, ndi chimodzimodzi.
Command flow Paziwonetsero, ma Host amderali komanso akutali ali ndi zida zomwezo pano. 1. Chotsani, fufuzani ndi kutsimikizira chiphaso cha anthu onse cha STSAFE-A110 chomwe chasungidwa mugawo 0 lachigawo cha data

Yang'anani satifiketi pogwiritsa ntchito chofotokozera chalaibulale ya cryptographic. Werengani satifiketi ya CA (yomwe ikupezeka kudzera mu code). Yang'anirani satifiketi ya CA pogwiritsa ntchito cholembera chalaibulale ya cryptographic. Tsimikizirani kutsimikizika kwa satifiketi pogwiritsa ntchito satifiketi ya CA kudzera mu library ya cryptographic. Pezani kiyi wagulu kuchokera ku satifiketi ya STSAFE-A110 X.509. 2. Pangani ndi kutsimikizira siginecha pa nambala yotsutsa: Pangani nambala yotsutsa (nambala yachisawawa). Hashi vuto. Pezani siginecha pazovuta zachangu pogwiritsa ntchito kiyi yachinsinsi ya STSAFE-A110 0 kudzera pa
STSAFE-A1xx pakati. Sinthani siginecha yopangidwa pogwiritsa ntchito laibulale ya cryptographic. Tsimikizirani siginecha yopangidwa pogwiritsa ntchito kiyi yapagulu ya STSAFE-A110 kudzera mulaibulale yachinsinsi. Izi zikamveka, wolandirayo amadziwa kuti zotumphukira kapena IoT ndizowona.
Kuyanjanitsa
Kodi example imakhazikitsa kulumikizana pakati pa chipangizo cha STSAFE-A110 ndi MCU chomwe chalumikizidwa. Kuphatikizikako kumalola kusinthanitsa pakati pa chipangizocho ndi MCU kutsimikiziridwa (ndiko kuti, kusaina ndikutsimikiziridwa). Chipangizo cha STSAFE-A110 chimatha kugwiritsidwa ntchito pokhapokha kuphatikiza ndi MCU yomwe imaphatikizidwa. Kuphatikizikaku kumakhala ndi MCU yolandila yomwe imatumiza kiyi ya MAC yolandila ndi kiyi yachinsinsi ya STSAFE-A110. Makiyi onsewa amasungidwa ku NVM yotetezedwa ya STSAFE-A110 ndipo iyenera kusungidwa ku flash memory ya chipangizo cha STM32. Mwachisawawa, mu example, wolandira MCU amatumiza makiyi odziwika bwino ku STSAFE-A110 (onani kutuluka kwa lamulo pansipa) omwe amalimbikitsidwa kuti agwiritse ntchito pazowonetsa. Code imalolanso kupanga makiyi osasintha. Komanso, code example amapanga kiyi ya envelopu yakumaloko pomwe malo ofananirako alibe kale mu STSAFE-A110. Malo a envulopu akamakhala ndi anthu, chipangizo cha STSAFE-A110 chimalola MCU yochititsa chidwi kukulunga/kumasula envulopu yakumaloko kuti asunge makiyi kumbali ya MCU yolandila. The pairing kodi example iyenera kuchitidwa bwino musanapereke code yonse yotsatirayiamples.

Ogula akuyenera kupeza zidziwitso zaposachedwa kwambiri pazogulitsa za ST asanapange maoda. Zogulitsa za ST zimagulitsidwa motsatira mfundo za ST ndi zogulitsa zomwe zilipo panthawi yovomerezeka. Ogula ali ndi udindo wosankha, kusankha, ndi kugwiritsa ntchito zinthu za ST ndipo ST sichikhala ndi udindo pa chithandizo cha pulogalamu kapena kupanga zinthu za ogula. Palibe chilolezo, chofotokozera kapena kutanthauza, ku ufulu uliwonse waukadaulo womwe umaperekedwa ndi ST apa. Kugulitsanso zinthu za ST zomwe zili ndi zosiyana ndi zomwe zafotokozedwa pano sizidzathetsa chitsimikizo chilichonse choperekedwa ndi ST pazogulitsa zotere. ST ndi ST logo ndi zizindikilo za ST. Kuti mumve zambiri za zizindikiro za ST, onani www.st.com/trademarks. Mayina ena onse azinthu kapena ntchito ndi eni ake. Zomwe zili m'chikalatachi zimaloŵa m'malo ndi kulowa m'malo zomwe zidaperekedwa kale m'matembenuzidwe am'mbuyomu a chikalatachi.
