Post-Quantum Cryptography

Cornerstone for Security in the Coming Quantum Computing Era

Sponsored by PSW Science Member Frederica Darema

About the Lecture

Cryptography is the cornerstone and foundation of cybersecurity. Public-key cryptography has been deployed successfully to secure communications and establish trusted platforms. However, quantum computers have the potential to undermine current cryptographic defenses.

This lecture will introduce efforts to develop quantum resistant cryptography, post-quantum cryptography, and it will focus on efforts at the National Institute of Standards and Technology (“NIST”) to develop cryptographic standards for the quantum era.

The presentation will highlight challenges in standardizing post-quantum cryptography and will discuss strategies for transition to and adoption and adaption of quantum resistant cryptographic methods and standards.
