如何使用最新的微控制器來(lái)簡(jiǎn)化嵌入式安全

　　Makers and vendors of microcontrollers， that fundamental element of so many IoT systems and devices， now also recognize the importance of security and are building hooks into their hardware and software libraries that ease development and lighten the developer’s security burden.

　　A prime example is the Synergy Platform from Renesas Electronics America. This not only includes a series of ARM?-based microcontrollers such as the S1， S3 and S7 series， but an entire software package designed to give developers a jump start by providing drivers， an RTOS， middleware， frameworks and libraries right out of the box.

　　Included in the Synergy Software Package （SSP） is a security and encryption module that developers can leverage to properly secure their device. While it’s good to have these software components available， developers still need to understand how to apply these resources to the three primary elements of embedded security： authentication， integrity and availability.
