Post-quantum public-key encryption: what’s it all about?

Read Original

This technical article provides an introduction to post-quantum public-key encryption, explaining the need to move beyond RSA and Diffie-Hellman due to quantum computing threats. It breaks down a toy cryptosystem to illustrate core concepts, compares it to real proposed systems, and aims to demystify the field for those with a basic understanding of classical cryptography.
