　　如何用一个芯片来保护物联网设备通信

　　锁定物联网设计需要的不仅仅是加密消息。开发人员需要通过身份验证、安全会话和安全消息来扩展底层机密密钥的安全性。然而，完整的安全链的设计、实现和功能方面的复杂性导致许多项目为了成本和进度而危及安全。

　　然而，这种妥协的需求正在减少，这在很大程度上是因为开发人员可以使用设备轻松地实现物联网设备和其他深层嵌入式系统的全面安全特性。一个这样的设备是集成的maxq1061。

　　此功能将描述物联网安全系统工作之前推出的maxq1061和如何它可以用来快速解决传输层的安全性。

　　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）.
