該解決方案中的simpler硬化物聯網安全的Wi - Fi的連接設計

　　Wi-Fi連接是許多物聯網設備的關鍵要求和黑客最喜愛的目標。弱安全實現使設備在正在進行的網絡通信中滲透。更糟的是，物聯網設備可以在其生命周期早期遭受攻擊時，該設備試圖加入受信任的網絡。

　　使用從德克薩斯儀器的雙核無線微控制器，工程師可以很容易硬化安全物聯網設備在整個產品生命周期，并支持多層終端到終端的安全策略。

　　Security components

　　Security in any system requires a multilayered approach. Although data encryption often gains the most attention among security measures， it is only one aspect of a robust security policy. Black-hat methods such as man-in-the-middle attacks exploit any weakness well before encrypted data exchange begins. Indeed， secure hosts authenticate clients to ensure that only authorized users， devices， or other systems gain access. Conversely， those clients authenticate the host to verify its identity.

　　This kind of mutual authentication lies at the heart of secure applications， but it ultimately relies on more fundamental mechanisms and policies. Foremost among these， secret keys and an established root of trust are the building blocks of any secure application. In the kind of public key infrastructure （PKI） typically used on the Internet， public keys paired with secret private keys provide essential validation of an entity’s identity. The X.509 certificate standard wraps the entity’s public key in a broader context that documents that identity， building on a chain of certificates to provide a solidly grounded root of trust for the application.
