Quantum Computers May Put Internet Traffic at Risk. NIST Is Safeguarding Computers With New Standards. | NIST
Quantum computers present a significant challenge to the digital protections we currently rely on. Modern cryptography secures everything from bank accounts to government secrets by using math problems that today's computers cannot solve. However, as quantum machines advance, they threaten to crack these codes and expose sensitive data. This includes a major risk known as harvest now, decrypt later, where bad actors intercept and store encrypted information today to unlock it once quantum technology matures.
NIST expert Andrew Regenscheid emphasizes that we must prepare now. Even though large-scale, cryptographically relevant quantum computers do not exist yet, the time required to update systems across the global internet is extensive. Organizations and developers need to inventory their systems, identify sensitive data, and plan for the transition to post-quantum cryptography standards. These standards are designed to withstand the processing power of future quantum machines.
The agency has finalized three new post-quantum encryption standards after a decade of open, worldwide public analysis. These standards provide a mathematical foundation for securing future systems against advanced threats. The transition requires collaboration across international standards bodies, hardware manufacturers, and software developers to ensure that the new encryption is integrated effectively into products.
For the average individual, the priority is maintaining updated systems. Setting devices to install security patches automatically ensures that updates reach your hardware as soon as they become available. As technology providers adopt these new standards over the next decade, users will benefit from improved security that shields personal information from future computational risks. Moving to these new methods is a critical step in preserving privacy and data integrity in an era of rapid technological progress.
