There is no doubt that quantum technology will deliver a magnitude of benefits, solving very specific problems that even the fastest supercomputers cannot solve. Consider the impact quantum applications will have on satellite communications, autonomous driving vehicles, and molecular mapping capabilities.
Yet, many exciting innovations that quantum technology promises may never be realized if we don’t take a proactive posture first to protect our data and systems, and prepare for the future. Collectively, we want to realize all of the benefits of quantum without compromising security.
The fact is, quantum computers will be able to break the cryptography underlying public key infrastructure (PKI), posing an unprecedented problem for encryption and authentication that enterprises put their trust in today. The services and infrastructure that we depend on most for our security, governance, public health, and safety are already at risk for cyber-attacks. That risk will increase exponentially with the advent of quantum computers.
The NIST National Cybersecurity Center of Excellence (NCCoE) has already put in place several practices “to ease the migration from the current set of public-key cryptographic algorithms to replacement algorithms that are resistant to quantum computer-based attacks,” according to its latest update.
