在(zai)藍牙(ya)、LoRa、WIFI、NB-IOT等無(wu)線(xian)通信模(mo)(mo)塊中(zhong)引入安(an)(an)全(quan)芯片(pian),把密(mi)鑰(yao)存儲(chu)在(zai)安(an)(an)全(quan)芯片(pian)內,會(hui)保障嵌(qian)入式(shi)設備的安(an)(an)全(quan)。因為安(an)(an)全(quan)芯片(pian)可以抗各種物理攻擊,防止密(mi)鑰(yao)被竊取(qu)。為了簡化用(yong)戶開發,可以把安(an)(an)全(quan)芯片(pian)嵌(qian)入無(wu)線(xian)模(mo)(mo)塊中(zhong),這樣開發者只(zhi)要采(cai)用(yong)了該安(an)(an)全(quan)無(wu)線(xian)模(mo)(mo)塊,可以快速簡單的實(shi)現(xian)設備的安(an)(an)全(quan)和知(zhi)識(shi)產權保護(hu)。
1.數據加密傳輸
2.設備防偽認(ren)證
3.密鑰安(an)全存(cun)儲(chu)、防數據外(wai)泄
4.核心代碼(ma)保(bao)護、防破(po)解拷貝
5.固(gu)件更新認證和校驗
