在物聯網節點的認證將要求SHA和AES解決方案

　　物聯網是關于共享，是數據，控制或一般訪問。那些完全理解這一點的人聽那些最大聲的安全-也了解需要采取的措施，以確保任何安全問題得到緩解。雖然不可能對所有通過公共網絡傳輸的數據進行加密，但問題仍然在于，有時這些數據可能傳遞給錯誤的代理。出于這個原因，許多人認為，認證將是根本，使物聯網。為了驗證任何代理訪問請求的身份的能力將極大地降低惡意活動的風險。

　　本文著眼于如何認證是實現一般，特別是它是如何實現在嵌入式系統中，突出了硬件和軟件的功能被集成在MCUs就是為了這個目的，以及他們如何可以幫助提高任何嵌入式系統連接到物聯網總體安全。

　　Secret sauce

　　The perceived threat presented by Internet access to sensitive systems is that it may leave those systems open to attack; in commerce that could leave financial data vulnerable， but in the IoT that may well translate to changing operating parameters in a machine， or access to a building. The difference here is that the world of commerce is still predominantly ‘overlooked’ by humans， while the IoT aims to largely remove the need and expense of human interaction.

　　In addition， the speed with which any changes may need to be executed could render human interaction unfeasible. Motor control is often cited as a case in point; being able to modify the parameters of a motor in reaction to varying loads can increase efficiency significantly， an action that needs to be autonomous to be fully effective. Ensuring any new parameters passed to the control circuit are valid requires authentication of the sender， the data， or both.
