第2706期:How to Protect Communications through Encryption(2)

Samsung, which sells Android smartphones, also indirectly described the issue in a small area at the bottom of a press release last month. Samsung said about RCS, “Encryption only available for Android-to-Android communication.”出售Android智能手机的三星也间接地描述了上个月新闻稿底部的小区域中的问题。 三星谈到RCS时说：“加密仅用于Android到Android通信。

”To avoid getting caught out when exchanging texts, experts recommend using encrypted messaging apps.为了避免在交换文本时被抓住，专家建议使用加密的消息传递应用程序。

Privacy supporters are big fans of Signal, which uses end-to-end encryption on all messages and voice calls. Signal is an app that is run by an independent nonprofit group based in Mountainview, California. It promises never to sell customer data. The group has also made its source code publicly available so that it can be examined by anyone “for security and correctness.”隐私支持者是信号的忠实拥护者，它在所有消息和语音呼叫上使用端到端加密。 Signal是一个由位于加利福尼亚州MountainView的独立非营利组织运行的应用程序。 它承诺永远不会出售客户数据。 该小组还公开提供了其源代码，以便任何人“为了安全性和正确性”对其进行检查。

Signal’s encryption method is so respected that it has been included into competitor WhatsApp.信号的加密方法非常受尊重，以至于已将其包括在竞争对手WhatsApp中。

End-to-end encryption is also the normal mode for Facebook Messenger, which like WhatsApp is owned by Meta Platforms.端到端加密也是Facebook Messenger的正常模式，就像WhatsApp一样，它归META平台拥有。

Telegram is an app that can be used for one-on-one discussions, group chats and broadcast “channels.” But Telegram does not use end-to-end encryption normally. Users have to turn on end-to-end encryption. And Telegram’s end-to-end encryption does not work with group chats.电报是一个应用程序，可用于一对一的讨论，小组聊天和广播“频道”。 但是电报不正常使用端到端加密。 用户必须打开端到端加密。 Telegram的端到端加密与小组聊天不起作用。

Cybersecurity experts have warned people against using Telegram for private communications.网络安全专家警告人们不要将电报用于私人通信。

Instead of using your phone to make calls through a wireless cellular network, you can make voice calls with Signal and WhatsApp. Both apps encrypt calls with the same technology that they use to encrypt messages.您无需使用手机通过无线蜂窝网络拨打呼叫，而是用信号和WhatsApp进行语音呼叫。 这两个应用程序都使用与它们用于加密消息的技术相同的技术加密调用。

There are other choices. If you have an iPhone, you can use Facetime for calls, while Android owners can use the Google Fi service. Both are end-to-end encrypted.还有其他选择。 如果您有iPhone，则可以将FaceTime用于呼叫，而Android所有者可以使用Google FI服务。 两者都是端到端加密的。

However, with all these choices, the person on the other end will also have to have the app.但是，有了所有这些选择，另一端的人也必须拥有该应用程序。

WhatsApp and Signal users can choose the privacy setting they want in the settings. Such choices include hiding an IP address during calls to prevent your general location from being guessed.WhatsApp和信号用户可以在设置中选择所需的隐私设置。 这样的选择包括在通话过程中隐藏一个IP地址，以防止您的一般位置被猜测。
