Post-quantum Cryptography

Public-key cryptography is essential for secure communication on the internet (e.g., for e-banking) and for authentication (e.g., digital signatures). A sufficiently powerful quantum computer would be capable of breaking most of the public-key cryptographic methods used today. Post-quantum cryptography (PQC) offers new methods that remain secure even if an attacker has access to a quantum computer.

In this course, we first explore the current state of quantum computing, the resulting risks to today’s cryptographic methods, and how PQC can save the day. In the second part, we examine the new PQC algorithms recently standardized by NIST and look into migration strategies for a secure transition into the post-quantum era.

Target Audience:

This course is intended for anyone who wants to gain a fundamental understanding of post-quantum cryptography.

Prerequisites:

Basic computer skills are required. Prior knowledge of cryptography in computer science (e.g., TLS/SSL) is beneficial but not necessary.
