Cyber Security in a Post-Quantum World

by Weronika Wiesiolek

This is the 5^th PRIMER of the FIN-TECH and DIGITAL ASSETS series. 

In this paper we discuss:

• Technical principles and standards of post-quantum cryptography (PQC); 
• Motivations behind the unification approach;
• International governmental initiatives for PQC;
• The curse of cryptographic discovery: Why implementation matters
• Industrial engagement from major private-sector actors;
• The cost of the transition from pre-quantum to post-quantum cryptography; and
• Whether there’s an alternative to PQC.
