How End-to-End Encryption works | The Signal Protocol and Privacy Vs Security

English subtitles are available now!
This video talks about End-to-End Encryption, and basically why governments should not break it,
trying to get chat records and traces of fake messages.
Privacy is a big issue these days, and encryption is the cornerstone of all internet security and privacy.
In this video, See how it works in somewhat detail, where I will explain basics of encryption with Caesar cipher, then we will ramp it up and talk a bit about AES, talk a lot about Key Exchange protocols and Asymmetric Encryption techniques like Diffie Hellman Key Exchange and RSA, respectively.
We will also talk a bit about Trap door / one way functions, especially prime factorization.
Finally we will see the overview of Signal Protocol (and its two parts: Extended Triple Diffie Hellman and Double Ratchet), the method used by Whatsapp and Signal to encrypt its messages.
TOO MUCH TECHNICAL STUFF?
Well I end the video with a monologue about privacy and security, and why governments shouldn't break it.
Wow, I just described my whole video here.
Wish to read further about how WhatsApp's encryption works?
(There would be a link around the bottom of the page to a PDF in the following link)
faq.whatsapp.c...
Signal Protocol:
signal.org/docs/
Anyway, here are timestamps!
00:00 - 01:31 Introdution to the topic
01:32 - 02:31 Encryption Basics with Caesar Cipher
02:32 - 03:56 Problems with basic encryptions (strength and key sharing)
03:57 - 05:00 The Maths of Trap Door
05:01 - 06:40 RSA and Diffie Hellman
06:41 - 09:02 The Signal Protocol
09:03 - 12:37 Privacy Vs Security and Conclusion

    Hate maths and science? You can always skip ahead, even though I recommend you watch the technical stuff. But still, if you really don't want it, I would highly suggest to watch from 09:00 onwards, you really should not miss that.

    As someone who works in infosec, I really appreciate how you explained encryption is such simple language, and make the concept so much easier for everyone to grasp. ofcourse one might want to argue that "encryption is a lot more complicated than that", but I honestly think that people understanding at the level you explained would already solve so much misunderstanding about encryption and why letting governments have back-doors aren't worth the cost to us as a society.

  • @HarshitRautela

    @HarshitRautela

    Жыл бұрын

    That all happens before you hit send and before encryption kicks in. All the processing is done on the phone in that case, you can try this: If you paste a link and quickly send it without giving WhatsApp on your phone a chance to get a preview of your link, it will be sent as plain text link without any extra stuff. Instagram isn’t end-to-end encrypted, and it generates the preview of the link after you send the message.

    Even your keyboard knows what you are typing. WhatsApp or any other app like Telegram/signal can identify links, but that processing and data fetch is done on the phone, not on the servers of companies. That data isn’t stored and sent to the servers.
