在WhatsApp部署关键的透明度

WhatsApp has launched a new cryptographic security feature to automatically verify a secured connection based on key transparency.
WhatsApp推出了一项新的加密安全功能，根据密钥透明度自动验证安全连接。
The feature requires no additional actions or steps from users and helps ensure that a conversation is secure.
该功能不需要用户的额外行动或步骤，有助于确保对话的安全性。
Key transparency solutions help strengthen the guarantee that end-to-end encryption provides to private, personal messaging applications in a transparent manner available to all.
密钥透明度解决方案有助于加强端到端加密以所有人都可使用的透明方式为私人、个人信息传递应用提供的保障。
We have published an open-source library called Auditable Key Directory (AKD). This enables anyone to verify audit proofs of the directory’s correctness. This underpins our key transparency deployment.
我们发布了一个开源的库，叫做可审计的密钥目录（AKD）。这使得任何人都可以验证目录的正确性的审计证明。这支撑了我们的密钥透明度部署。

End-to-end encryption is the foundation of private messaging on WhatsApp, helping to ensure that only you and the person you’re communicating with can read what’s sent, and nobody in between, not even WhatsApp. It is among the most widely used deployments of end-to-end encryption and relies on public key cryptography first developed in the 1970s. From a technical point of view, for end-to-end encryption to be trusted, the “ends” of a conversation need to know that one another’s encryption keys are authentic and valid.

端到端加密是WhatsApp上私人信息的基础，有助于确保只有你和与你交流的人可以阅读发送的内容，而中间没有人，甚至WhatsApp也不能。它是最广泛使用的端到端加密的部署之一，并依赖于20世纪70年代首次开发的公钥密码学。从技术角度看，要使端到端加密得到信任，对话的 "两端 "需要知道彼此的加密密钥是真实和有效的。

To do so, our most security conscious users have always been able to take advantage of our security code verification feature available under a user’s contact info. When in person, keys can be validated with a quick QR code scan or, if remote, sharing the unique 60-digit code.

为此，我们最具安全意识的用户一直能够利用我们的安全代码验证功能，该功能在用户的联系信息下可用。当面时，可以通过快速的二维码扫描来验证钥匙，如果是远程，可以分享独特的60位数字代码。

This is the one of the strongest ways of verifying if a connection is secure. But in reality we know that double checking a long code is cumbersome, and our team has been look...
