How End-to-End Encryption works | The Signal Protocol and Privacy Vs Security
Показать описание
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)
Signal Protocol:
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
