如何用一個芯片來保護物聯網設備通信

　　鎖定物聯網設計需要的不僅僅是加密消息。開發人員需要通過身份驗證、安全會話和安全消息來擴展底層機密密鑰的安全性。然而，完整的安全鏈的設計、實現和功能方面的復雜性導致許多項目為了成本和進度而危及安全。

　　然而，這種妥協的需求正在減少，這在很大程度上是因為開發人員可以使用設備輕松地實現物聯網設備和其他深層嵌入式系統的全面安全特性。一個這樣的設備是集成的maxq1061。

　　此功能將描述物聯網安全系統工作之前推出的maxq1061和如何它可以用來快速解決傳輸層的安全性。

　　Security is fundamental to the IoT

　　Underlying the vision of the IoT， users expect applications to process data streams to provide detailed information about the user， their environment， and their equipment. The ability to protect these applications and ensure the integrity and authenticity of data is inherent in this vision. Yet， well-publicized attacks on systems and data continue to call into question that ability. Accordingly， interest has grown rapidly for more effective solutions for securing data and systems.

　　At the device level， designers can already find MCUs that integrate hardware accelerators for encrypting and decrypting data using a wide variety of ciphers including AES， SHA， and 3DES， among others. Yet， data encryption/decryption is only one piece of a larger set of capabilities required to secure IoT applications using standard security protocols such as TLS （Transport Layer Security）.
