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.
资源贫乏的Android手机和IoT设备没有使用现代加密服务的处理能力，这使其很容易受到黑客攻击。 这就是Google推出Adiantum的原因，Adiantum是一种针对低资源Android设备的超快速加密标准。
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手机(如Google Pixel或Samsung Galaxy系列的任何产品)都是围绕高级加密标准(AES)构建的。 使用AES，您电话上的所有信息均被加密，只有经过验证的用户才能访问数据。 但是，许多Android手机和智能设备无法使用AES，因为它们没有足够的处理能力来快速加密和解密信息。 另外，它们通常没有内置的安全功能，例如指纹扫描仪或虹膜扫描仪。 这使得资源匮乏的Android设备(包括智能手表和物联网产品)非常容易受到攻击。
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是发展中国家的领先操作系统。 它是免费使用的，已经有很多应用程序，并且在低端设备上受支持。 谷歌甚至提出了创建Android Go OS的观点，该操作系统已针对低资源智能手机进行了优化。 这确实是一件好事，因为便宜的电话将互联网带到了许多发展中国家。 但是在某些方面，这加速了安全问题。
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.
制造商能够将Android OS安装在低资源设备上，例如廉价电话，廉价平板电脑，智能手表，智能电视和智能家居产品。 问题是：这些设备中的大多数功能不足以与高级加密标准一起使用。 这使得资源匮乏的设备容易受到黑客攻击。

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.
显然，在这种情况下，Google有两种选择：忽略该问题或找到一种对廉价设备进行加密的方法。 值得庆幸的是，该公司选择了后者。
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.
铁线蕨是对AES的低资源响应。 它可以比AES快五倍地加密和解密信息，并且几乎不需要电话或智能设备的任何处理能力。 这一新的加密标准将提高发展中国家的廉价电话的安全性，并使您的智能家居产品更不容易受到黑客攻击。
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.
谷歌花了很长时间开发Adiantum，尽管在现实世界中花了很多时间，但开发人员仍对Adiantum是低资源电话和物联网设备的未来充满信心。
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安全团队非常聪明，可以专注于IoT设备。 目前，公众非常关注智能家居产品的安全性，尽管所有手机最终都将具有足以使用AES的强大功能，但对于物联网设备我们不能一视同仁。 智能家居产品越来越小，越来越智能，因此我们将需要安全解决方案，例如Adiantum，以在不消耗过多处理能力的情况下对我们的所有信息进行加密。 要了解有关铁线蕨的更多信息，包括所有技术细节，请点击下面的链接。
