How to prepare for post-quantum computing security

With quantum computers on the horizon, businesses are preparing for a potential security impact on cryptographic data protections. The potential for quantum computers to crack traditional encryption algorithms is prompting urgent work to establish quantum-resistant cryptographic standards. Organisations should begin preparing for post-quantum migration, including conducting a data inventory and risk assessment of future exposure to quantum computing. It is recommended that businesses consider multiple PQC algorithms for added security and also make use of quantum key distribution (QKD).
