如何使用最新的微控制器來簡化嵌入式安全

　　物聯網（物聯網）繼續(xù)成為一個現實與設備連接到互聯網每天數以百萬計的基礎上。由于這可能是令人興奮的，與許多機會開放的創(chuàng)新，為物聯網的設備和系統的開發(fā)人員面臨著許多挑戰(zhàn)，其中最關鍵的是確保他們的設備，并確保最終用戶的隱私。值得慶幸的是，新的微控制器（MCU）的出現，大大簡化了安全的任務，但這些功能只是不如開發(fā)商的能力使用他們。

　　這是有點令人驚訝的安全，一直是一個事后的許多開發(fā)商。這是一個錯誤，因為它奠定了家庭，車輛，制造業(yè)，零售業(yè)和關鍵基礎設施易受攻擊。然而，盡管歷史不愿意解決安全，物聯網現在迫使設計師更認真地考慮安全方面，因為他們開發(fā)嵌入式系統，幸運的是，他們發(fā)現他們不是單獨解決它。

　　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.
