　　在物联网节点的认证将要求SHA和AES解决方案

　　物联网是关于共享，是数据，控制或一般访问。那些完全理解这一点的人听那些最大声的安全-也了解需要采取的措施，以确保任何安全问题得到缓解。虽然不可能对所有通过公共网络传输的数据进行加密，但问题仍然在于，有时这些数据可能传递给错误的代理。出于这个原因，许多人认为，认证将是根本，使物联网。为了验证任何代理访问请求的身份的能力将极大地降低恶意活动的风险。

　　本文着眼于如何认证是实现一般，特别是它是如何实现在嵌入式系统中，突出了硬件和软件的功能被集成在MCUs就是为了这个目的，以及他们如何可以帮助提高任何嵌入式系统连接到物联网总体安全。

　　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.
