Course overview

This course maps out the essential landscape of post-quantum cryptography, guiding you from foundational threats to real-world deployment. It begins by explaining how quantum computers break RSA encryption and how quantum key distribution uses physics for secure communication. The journey progresses through the mathematical core of modern security, focusing on lattice-based problems and the Learning With Errors scheme. You will examine NIST's standardization process, analyze the Kyber key encapsulation mechanism and Dilithium digital signature algorithm, and review real-world adoption strategies by companies like Google and Cloudflare to prepare for Q-Day.

Who this course is for

This course serves IT and security professionals who need to understand how to protect systems against quantum attacks. It is also valuable for developers planning to implement quantum-resistant cryptography. A basic familiarity with public-key encryption is helpful, but the instructors explain complex concepts like lattice mathematics and Shor's algorithm from the ground up, making the material accessible to a wide technical audience preparing for the coming cryptographic transition.

How to study this sequence

Begin with the threat landscape in the opening lessons to understand why current encryption must change. Progress into the mathematical foundations with lessons on lattice-based cryptography and the Learning With Errors problem before diving into the NIST standards. Focus on comparing theoretical concepts with their practical implementations in Kyber and Dilithium. Pay close attention to the final lessons on deployment strategies and hybrid solutions, as they connect academic theory to the current migration plans of major tech firms.

What you should be able to do

You will be able to articulate how quantum computers threaten asymmetric cryptography and explain the operation of leading post-quantum solutions. You will recognize the mathematical logic behind lattice-based standards like Kyber and Dilithium and understand NIST's selection criteria. This prepares you to evaluate quantum-safe migration strategies and discuss practical deployment models for securing communications against the harvest-now-decrypt-later threat.
