To protect communications in a future where quantum computers will be capable of cracking the prime number factoring that is the basis of today's encryption, the National Institute of Standards and Technology has selected 15 promising new approaches to encryption and data protection to form the core of the first post-quantum cryptography standard

In December 2016, NIST issued a call for new algorithms that would be less susceptible to a quantum computer's attack. Within a year, it had received 69 submissions for replacements for algorithms dealing with public key cryptography for encryption, key establishment and digital signatures.

That initial group was narrowed to 26 in January 2019. Because the future capabilities of quantum computers remain unclear, the 26 candidates were built around multiple mathematical approaches.
