Deep dive into a post-quantum key encapsulation algorithm

What this post added

This post introduces the concept of Key Encapsulation Mechanisms (KEMs) and their importance in secure communication, particularly in the context of post-quantum cryptography. It explains the mathematical underpinnings of KEMs, focusing on the Learning With Errors (LWE) problem and its relation to lattices, and details the construction of FrodoKEM as an example. This contributes to the data privacy thread by addressing the future security landscape and the need for quantum-resistant encryption to maintain long-term data protection.
