Germany's National Research Center for Applied Cybersecurity is urging organizations to initiate post-quantum cryptography preparations immediately, as the transition is expected to be complex and time-consuming. Experts warn that delaying this process may result in insufficient protection against quantum computer attacks, which could compromise the security of sensitive information. The center recommends taking short-term measures to prepare for a future where classical cryptography is no longer effective. This includes assessing current cryptographic systems and identifying areas that require post-quantum upgrades. The looming threat of quantum computers rendering existing cryptography obsolete necessitates prompt action, with experts emphasizing that the timeline for cryptographic migration is narrowing due to rapid advancements in post-quantum technologies1. This matters to practitioners because failing to prepare for post-quantum cryptography now may leave their organizations vulnerable to quantum-powered attacks in the near future.
