Post-quantum Cryptography: Protecting Critical Data and Enhancing Cyber Resilience

Abstract

Quantum computing represents a significant threat to the asymmetric cryptographic algorithms currently used to protect the traditional data security infrastructure today’s enterprises depend upon. With Gartner predicting that by 2029 advances in quantum computing will render applications, data and networks protected by asymmetric cryptography unsafe, organisations must begin preparations to transition to post-quantum cryptography (PQC). Organisations that fail to prepare for quantum today risk potentially exposing their sensitive data on a massive scale, as threat actors are already collecting encrypted enterprise data in anticipation of future quantum decryption capabilities. The migration to PQC involves updating risk registers and enabling the crypto agility that supports the rapid implementation of new algorithms and ensures organisations can adapt fast to new regulatory standards.
