Low-resource Android phones and IoT devices don’t have the processing power to use modern encryption services, which makes them vulnerable to hacking. That’s why Google is introducing Adiantum, a super-fast encryption standard for low-resource Android devices.

資源貧乏的Android手機和IoT設備沒有使用現代加密服務的處理能力，這使其很容易受到黑客攻擊。 這就是Google推出Adiantum的原因，Adiantum是一種針對低資源Android設備的超快速加密標準。

Popular Android phones, like the Google Pixel or anything from the Samsung Galaxy line, are built around the Advanced Encryption Standard (AES). With the AES, all of the information on your phone is encrypted and only verified users can access the data. But a lot of Android phones and smart devices can’t use the AES because they don’t have enough processing power to quickly encrypt and decrypt information. Plus, they usually don’t have built-in security features, like fingerprint scanners or iris scanners. This leaves low-resource Android devices, including smart watches and IOT products, very easy to compromise.

流行的Android手機(如Google Pixel或Samsung Galaxy系列的任何產品)都是圍繞高級加密標準(AES)構建的。 使用AES，您電話上的所有信息均被加密，只有經過驗證的用戶才能訪問數據。 但是，許多Android手機和智能設備無法使用AES，因為它們沒有足夠的處理能力來快速加密和解密信息。 另外，它們通常沒有內置的安全功能，例如指紋掃描儀或虹膜掃描儀。 這使得資源匱乏的Android設備(包括智能手表和物聯網產品)非常容易受到攻擊。

As you may know, Android is the leading OS in developing countries. It’s free to use, it already has a lot of apps, and it’s supported on lower end devices. Google has even made a point to create the Android Go OS, which is optimized for low-resource smartphones. This is genuinely a great thing, as cheap phones have brought the internet to a lot of developing counties. But in some ways, this has accelerated a security problem.

如您所知，Android是發展中國家的領先操作系統。 它是免費使用的，已經有很多應用程序，并且在低端設備上受支持。 谷歌甚至提出了創建Android Go OS的觀點，該操作系統已針對低資源智能手機進行了優化。 這確實是一件好事，因為便宜的電話將互聯網帶到了許多發展中國家。 但是在某些方面，這加速了安全問題。

Manufacturers are capable of putting Android OS on low-resource devices, like cheap phones, cheap tablets, smart watches, smart TV’s, and smart home products. Here’s the issue: most of these devices aren’t powerful enough to work with the Advanced Encryption Standard. This leaves low-resource devices?vulnerable to hacking.

制造商能夠將Android OS安裝在低資源設備上，例如廉價電話，廉價平板電腦，智能手表，智能電視和智能家居產品。 問題是：這些設備中的大多數功能不足以與高級加密標準一起使用。 這使得資源匱乏的設備容易受到黑客攻擊。

Obviously, Google has two choices in this situation: ignore the problem or find a way to encrypt cheap devices. Thankfully, the company has chosen the latter option.

顯然，在這種情況下，Google有兩種選擇：忽略該問題或找到一種對廉價設備進行加密的方法。 值得慶幸的是，該公司選擇了后者。

Adiantum is the low-resource response to AES. It can encrypt and decrypt information five times faster than AES, and requires hardly any processing power from the phone or smart device. This new encryption standard should increase the security of cheap phones in developing counties and also make your smart home products less vulnerable to hacking.

鐵線蕨是對AES的低資源響應。 它可以比AES快五倍地加密和解密信息，并且幾乎不需要電話或智能設備的任何處理能力。 這一新的加密標準將提高發展中國家的廉價電話的安全性，并使您的智能家居產品更不容易受到黑客攻擊。

Google has spent a long time developing Adiantum, and even though it hasn’t spent a lot of time in the real world, developers are confident that Adiantum is the future of low-resource phones and IoT devices.

谷歌花了很長時間開發Adiantum，盡管在現實世界中花了很多時間，但開發人員仍對Adiantum是低資源電話和物聯網設備的未來充滿信心。

The Google Security Team is smart for focusing so much on IoT devices. Right now, the public is very concerned about the security of smart home products, and while all phones will eventually be powerful enough to use AES, we can’t say the same about IoT devices. Smart home products are becoming smaller and smarter, so we’re going to need security solutions like Adiantum to keep all of our information encrypted without using up too much processing power.

Google安全團隊非常聰明，可以專注于IoT設備。 目前，公眾非常關注智能家居產品的安全性，盡管所有手機最終都將具有足以使用AES的強大功能，但對于物聯網設備我們不能一視同仁。 智能家居產品越來越小，越來越智能，因此我們將需要安全解決方案，例如Adiantum，以在不消耗過多處理能力的情況下對我們的所有信息進行加密。 要了解有關鐵線蕨的更多信息，包括所有技術細節，請點擊下面的鏈接。
