Delivering a Quantum Future
白書
More companies are starting to consider the impact that quantum computing will have on their business in the coming years. According to a survey by Deloitte, about half of all companies believe that they are vulnerable to a “harvest now, decrypt later” attack, where encrypted information is stored until a future quantum computer can decrypt the data.2 No wonder, then, that 61% of firms have either conducted an assessment of their readiness or plan to analyze the issue within five years.
In 2022, the National Institute of Standards and Technology (NIST) made a significant decision to help companies prepare for a world where quantum computing is commonplace. The decision was also an effort to help protect today’s data from tomorrow’s quantum computers.1 The U.S. technology agency selected four algorithms for encryption methods to replace public key infrastructure (PKI) algorithms currently in use as a way of protecting data encrypted today against quantum computers developed in the future.
Because data can be saved and archived, classified and sensitive information—which may need to be protected longer than a decade, or more—needs to be protected with quantum-resistant algorithms. The four algorithms selected by NIST represent an early milestone in the development of the post-quantum encryption standard.
