Securing Pervasive Connectivity

　　隨著物聯網的演變，隨意連接的前景。這反過來又推動安全性脫穎而出，因為它已經變得越來越重要，它現在觸及的數據和控制路徑的每一步，使其成為所有應用程序的積分。沒有比這更明顯的設備，將坐在‘邊緣’的網絡，節點將形成‘物’在物聯網。

　　如果離開無擔保，每一個這些‘東西’代表容易訪問到另一個私人網絡，提高在每一個垂直部門的關注與生產利用物聯網的希望。因此，集成設備制造商（IDM）正在越來越大的長度，加上先進的安全功能，他們所有的最新產品。

　　就像目前存在的威脅的多樣性，安全功能來在許多形狀和大小，并在那些旨在提供原始處理性能的設備和那些將引入智能從邊緣到網絡之間的變化。這些MCU的目的是使邊緣設備，如智能傳感器和遠程訪問的驅動器，將需要更先進的安全功能，在較小的，低功耗；面臨的一個挑戰，每個IDM想要開發物聯網的潛力。

　　A level of trust

　　The specific requirements of a node on the IoT will be dependent on how it is deployed; a device connected to a wired supply， such as a thermostat， may be less concerned with ultra-low power consumption than， say， a remote sensor. An actuator on a piece of manufacturing equipment would have access to all the power it needs， while a wearable device may need to harvest the energy it uses from its surroundings. What they do have in common， however， is a need to carry out their prime objective securely.

　　Fortunately， the need for security in a microcontroller has not just been ‘forced’ upon the industry; there have always been applications that value security， it’s just that the volume of devices expected to contribute to the IoT in the next decade or so will drive demand for these devices much higher than it has been in the past.
