今年早些时候，埃隆·马斯克 [在 Twitter 上表示](https://twitter.com/elonmusk/status/1519469891455234048)：Twitter 的 <ruby> 私信 <rt>  Direct Messages </rt></ruby>（DM）需要像 Signal 协议这样的 <ruby> 端到端加密 <rt>  End-to-End Encryption </rt></ruby>。


早在 2016 年，**爱德华·斯诺登**就 [要求](https://twitter.com/Snowden/status/808736772830195713) Twitter 的前首席执行官兼联合创始人**杰克·多尔西**添加 Signal 协议类似的安全措施到 Twitter 平台。


但是，这个协议从来没有被添加到 Twitter。它可能经过测试但还未部署实施。


根据最近的公告，Twitter 似乎即将实现这个安全协议 ?。


马斯克分享了他在公司演讲中的几张幻灯片，其中就包括为 Twitter 2.0 路线图规划的“**加密私信**”。


### ? Twitter 通信的 Signal 协议

虽然有一些安全研究员，例如 [黄文津](https://twitter.com/wongmjane)，已经在 Twitter 的 iOS 和 Android 应用程序中发现了对 [Signal 协议](https://github.com/signalapp/libsignal) 的代码引用。


但是直到现在，埃隆·马斯克才在 [推文](https://twitter.com/elonmusk/status/1596718851097755648) 中确认了该计划，该推文介绍了根据 **“Twitter 2.0”** 路线图将对 Twitter 平台进行的改进。


换句话说，埃隆·马斯克正式确认 Twitter 即将推出**加密私信**。


![twitter dm signal protocol](/data/attachment/album/202212/01/094113e66l71a17almf60n.jpg)


**对于那些不知道 Signal 协议的人**，我们简要地介绍一下 Signal 协议：Signal 协议是一种开源的加密协议，它允许以 <ruby> <a href="https://en.wikipedia.org/wiki/Forward_secrecy">  完全前向保密 </a> <rt>  perfect forward secrecy </rt></ruby>（PFS）方式实施端到端加密。


该协议使用 “<ruby> 双棘轮算法 <rt>  Double Ratchet algorithm </rt></ruby>”，通信双方根据不断变化的共享密钥，来交换加密的消息。


这确保没有第三方可以得到通信消息的内容，因为共享密钥仅存在于通信双方的设备上。


[Signal](https://signal.org/en/) 应用程序充分利用了这个方法。但是，进一步来说，还有几个以隐私为中心的替代方案：


（LCTT 译注：Signal 协议是一种真正的端到端加密的通讯协议，号称是世界上最安全的通讯协议。只有参与通讯的用户可以读取并解密信息，而任何第三方（包括服务器）都无法查看到通讯的内容。总的来说，它可以防止潜在的窃听者（包括：通信服务商、互联网服务提供商甚至是该通讯系统的提供者），获取能够用以解密通讯内容的密钥。目前有大量即时通讯软件也使用或借鉴参考了 Signal 协议，例如：Skype、What'sApp、Facebook Messenger）


#### Signal 协议如何帮助 Twitter DM？


它可以防止恶意攻击者和政府去窥探 Twitter 用户的消息，从而使 Twitter 成为一个更加安全的平台。


Twitter 添加加密私信会对举报人、记者和社会活动家有益，因为他们经常会因其工作而面临被审查或成为攻击目标。


诚然，就隐私而言，加密私信可能不是最严格的保护措施。但**有总比没有好**。


### ? 加密消息应该成为通讯软件的标准


在这个动荡的信息时代，我们看到更多的恶意攻击者试图未经授权访问敏感信息。


端到端加密应成为所有通讯软件的必要标准，我希望 Twitter 能够尽快添加它。

Earlier this year, Elon Musk [tweeted](https://twitter.com/elonmusk/status/1519469891455234048?ref=news.itsfoss.com) that Twitter DMs needed end-to-end encryption like Signal.

Even back in 2016, **Edward Snowden** [asked](https://twitter.com/Snowden/status/808736772830195713?ref=news.itsfoss.com) **Jack Dorsey**, former CEO and Co-Founder of Twitter, to add something similar to the platform.

But, it never came to be. It was probably tested but never implemented.

With a recent announcement (kind of), this seems to be coming to fruition😌

Elon shared a few slides from his company talks, which included '**Encrypted DMs**' for the platform with the Twitter 2.0 roadmap.

## 🔒 Signal Protocol to Twitter DMs

![twitter encrypted dms](https://news.itsfoss.com/content/images/2022/11/Encrypted_DM_Twitter.jpg)

[Elon Musk](https://twitter.com/elonmusk?ref=news.itsfoss.com)

While some tinkerers like [Jane Manchun Wong](https://twitter.com/wongmjane?ref=news.itsfoss.com)** **(security researcher) found code references to the [Signal Protocol](https://github.com/signalapp/libsignal?ref=news.itsfoss.com) in Twitter's iOS and Android applications.

Elon Musk confirmed the plan for it in a [tweet](https://twitter.com/elonmusk/status/1596718851097755648?ref=news.itsfoss.com) about the improvements set to come to the platform under the '**Twitter 2.0**' roadmap.

In other words, Elon confirmed that encrypted DMs are coming soon.

**For those who don't know:** Signal Protocol is an open-source cryptographic protocol that allows the implementation of end-to-end encryption in a perfect forward secrecy ([PFS](https://en.wikipedia.org/wiki/Forward_secrecy?ref=news.itsfoss.com)) manner.

The protocol uses a '*Double Ratchet algorithm*' where two parties exchange encrypted messages based on a constantly changing shared secret key.

This ensures that no third party can access the message's contents, as the shared keys only exist on the devices of the two parties.

The [Signal](https://signal.org/en/?ref=news.itsfoss.com) app makes the best of it. However, you do have several privacy-focused alternatives if you want to explore:

**How can it help with Twitter DMs? **

Well, it can make Twitter a more secure platform by preventing malicious actors and governments from snooping around the messages of Twitter users.

The implementation of Encrypted DMs can be beneficial for whistleblowers, journalists, and activists who are constantly at risk of being censored or targeted for their work.

Sure, encrypted DMs may not be the most extreme protection measure in terms of privacy. **But it is better than nothing.**

## 🔏 Encrypted Messaging Should be the Standard

In these turbulent times, we see more malicious actors trying to gain unauthorized access to sensitive information than ever before.

Support for End-to-end encryption should be the de facto standard for all messaging platforms, and I hope that Twitter adds it soon.
