隨著安全漏洞的抬頭，基于硬件的MCU解決方案占據中心舞臺

　　幾乎所有基于MCU的嵌入式系統-汽車，無人機，USB棒，車庫門開啟器，數碼相機，甚至耗材，如打印機墨盒-容易受到安全攻擊。

　　越來越多的記錄的安全漏洞，使用物聯網（物聯網）作為入口點，提高了安全意識，在設計界物聯網連接設備。通常情況下，故事涉及違規影響消費者和最終用戶。然而，其他類型的安全威脅至少同樣重要的設計工程師-最涉及盜竊，篡改，或破壞知識產權。

　　互聯網可能已經成為一個基于MCU的系統中最流行的切入點，但它遠遠不是唯一的一個。無擔保或未充分擔保的診斷端口一直是潛在的脆弱-作為汽車行業發現，主要是通過活動的“調諧器”社區。任何無線（或有線）通信鏈路也可以用作入口點。

　　Even the unattached MCU device （or its associated ROM） are subject to tampering and IP theft. Among other techniques， reverse-engineering specialists have developed techniques in which the chip’s mask layers are carefully ground down until the ROM layer is exposed. By closely analyzing which switches have been blown， the firmware code contained in them can be deduced.

　　MCU vendors have responded with multiple approaches to enhancing security for the firmware that runs their devices. Although these measures make firmware more secure， implementing them requires that the system design team understand how they work – and implement them correctly. This involves the extra effort， time， and cost for the system’s bill of materials （BOM）。 Computer-intensive security measures such as data encryption can require a more powerful MCU.
