Introduction to Post-Quantum Cryptography (PQC) Fundamentals Training by Tonex
Quantum computing is progressing from theoretical research to real technological capability, creating profound implications for the cryptographic systems that secure today’s digital world. Encryption mechanisms such as RSA, Diffie-Hellman, and Elliptic Curve Cryptography currently protect global communications, financial transactions, software updates, and identity systems, yet these algorithms will eventually become vulnerable to quantum-powered attacks. This course provides a clear introduction to the foundations of quantum computing and explains how emerging quantum algorithms threaten current cryptographic infrastructures.
The program examines Post-Quantum Cryptography (PQC) and the algorithms designed to withstand quantum-based attacks, including those selected through the NIST PQC standardization process. Participants also explore the organizational implications of the quantum transition, including cryptographic inventories, migration planning, and enterprise security architecture adjustments.
From a cybersecurity perspective, the emergence of quantum computing introduces long-term data confidentiality risks and new attack models such as “Harvest Now, Decrypt Later.” Organizations must begin preparing today to protect sensitive information that may remain valuable for decades. This course highlights how cybersecurity programs, governance frameworks, and cryptographic infrastructures must evolve to remain resilient in the post-quantum era.
