NIST post-quantum cryptography standardization is the process of setting rules for a new kind of security that can protect our information from being accessed by hackers. It's called post-quantum cryptography because it uses something called 'quantum computing' to make the security stronger than ever before. Quantum computing is a type of technology that uses the laws of physics to process information in a faster and more secure way than traditional computers. NIST is a government agency that is responsible for creating standards and giving out information about post-quantum cryptography. They are setting rules so that security companies can use post-quantum cryptography to keep our information safe. They are also working with the public, industry, and other experts to make sure that the standards they set are the best they can be.
