Learning with errors: Encrypting with unsolvable equations
Learning with errors scheme.
This video uses only equations, but you can use the language of linear algebra (matrices, dot products) to discuss lattices and learning with errors. Check out the resources below for more information.

How do you keep the messages in a group chat secure? Messaging layer security (MLS). The Double Ratchet algorithm provides end-to-end encryption for text messages between two people. But securing a group chat is much harder. MLS is the first standardized multi-party “key exchange” - a protocol for communication among groups of people or devices.

How do text messaging services like Signal and WhatsApp keep your text messages secure? The Double Ratchet algorithm. Let’s say Alice wants to send Bob an end-to-end encrypted message. She uses a key to lock up the message and Bob uses the same key to unlock the message. But what if they want to send a bunch of messages back and forth? Using the same key the whole time is not very secure. It wo...
