通過集成到微控制器的技術(shù)提高安全性

　　當(dāng)安全在我們的直接控制之下，這是日常生活中顯而易見的一個(gè)方面；我們鎖上門窗，我們不把貴重物品放在普通的視線里，我們在電子支付時(shí)保護(hù)我們的別針。然而，當(dāng)安全級(jí)別不是我們的直接控制下變得更加模糊；不清楚為什么安全是必要的，事實(shí)上，它是如何實(shí)現(xiàn)的。

　　越來越多的嵌入式電子設(shè)備出現(xiàn)了這種情況，因?yàn)樗鼈儸F(xiàn)在實(shí)現(xiàn)了某種程度的連接，但在歷史上對(duì)安全問題不敏感。

　　如果存在秘密連接，例如在生產(chǎn)能力聯(lián)網(wǎng)的工業(yè)設(shè)備，或醫(yī)療設(shè)備，使病人信息的訪問-危險(xiǎn)可能不清楚，或往往，甚至在當(dāng)?shù)卮嬖?。由于連通性是全球性的現(xiàn)象，遠(yuǎn)程攻擊的危險(xiǎn)也是如此，這增加了遠(yuǎn)遠(yuǎn)超出鄰近地區(qū)的安全問題。來自地球另一端的威脅可能是特定的——或者可能是無意的——瞄準(zhǔn)良性設(shè)備，并將這種威脅擴(kuò)展到它隨后訪問的任何其他設(shè)備。

　　因此，物聯(lián)網(wǎng)很可能會(huì)促進(jìn)嵌入式安全的問題，遠(yuǎn)遠(yuǎn)超出局域網(wǎng)或可見的威脅。

　　What is a security threat？

　　There are many aspects to security in electronic devices today. Predominantly， these can be categorized as threats to either content， intellectual property， or personal data. The trends behind the cost and benefits of adding connectivity are moving positively， but this is only possible thanks to another trend – the use of more diverse hardware solutions and the adoption of open source software.

　　While these are both， ostensibly， also positive， the effect is increased difficulty in guaranteeing security. When networking was first introduced， it was under the control of a small number of providers， which made the need for security almost moot. As connectivity has proliferated， the diversity in hardware and software solutions makes security harder to impose， unless you remain in complete control of your platform （such as Apple）。 Even then， threats can never be entirely mitigated. Security， therefore， is any method by which a threat can be curtailed or controlled. This accepts that threats cannot be entirely avoided but must， instead， have equal and preferably greater countermeasures.
