Quantum computers will deliver tremendous benefits, but they will also be able to break the cryptography underlying public key infrastructure (PKI). Quantum computing will be able to solve very specific hard problems that even the fastest supercomputers cannot solve in a reasonable amount of time. This poses an unprecedented problem for encryption that enterprises put their trust in today. Cryptography is the foundation of digital trust – a threat to cryptography is a serious threat to digital trust. In today's increasingly connected ecosystem, broken cryptography can result in unauthorized access to sensitive information, lack of control over connected devices, and potentially, pose great dangers. Consider cars, airplanes, satellites, energy grids. These durable, critical devices are highly vulnerable to attack, as these connected devices (IoT) have long in-field lives requiring their certificates to be updated. Imagine a state-sponsored attack hacking into the system and intercepting software security updates for a satellite. Long-lived devices need to be able to handle whatever cryptographic changes come our way.
