在藍牙、LoRa、WIFI、NB-IOT等無線(xian)通(tong)信模(mo)塊(kuai)中(zhong)引入安(an)全(quan)(quan)芯(xin)片(pian)(pian),把(ba)密(mi)鑰存儲在安(an)全(quan)(quan)芯(xin)片(pian)(pian)內,會保障嵌入式設備的安(an)全(quan)(quan)。因為安(an)全(quan)(quan)芯(xin)片(pian)(pian)可(ke)以抗各種物理攻擊,防止(zhi)密(mi)鑰被(bei)竊(qie)取(qu)。為了簡化(hua)用戶(hu)開發(fa),可(ke)以把(ba)安(an)全(quan)(quan)芯(xin)片(pian)(pian)嵌入無線(xian)模(mo)塊(kuai)中(zhong),這(zhe)樣開發(fa)者只要(yao)采用了該安(an)全(quan)(quan)無線(xian)模(mo)塊(kuai),可(ke)以快速簡單的實現設備的安(an)全(quan)(quan)和(he)知識產權保護。
1.數據加密傳輸
2.設備防偽認證(zheng)
3.密鑰安全存(cun)儲、防數據外泄
4.核心代碼保護、防破(po)解拷貝
5.固件(jian)更新認證和校驗
