Migration to Post-Quantum Cryptography

The advent of quantum computing technology will compromise many of the current cryptographic algorithms, especially public-key cryptography, which is widely used to protect digital information. Most algorithms on which we depend are used worldwide in components of many different communications, processing, and storage systems. Once access to practical quantum computers becomes available, all public-key algorithms and associated protocols will be vulnerable to criminals, competitors, and other adversaries. It is critical to begin planning for the replacement of hardware, software, and services that use public-key algorithms now so that information is protected from future attacks.

Initiating the development of practices to ease migration from the current set of public-key cryptographic algorithms to replacement algorithms that are resistant to quantum computer-based attacks.

These practices will take the form of white papers, playbooks, and demonstrable implementations for organizations. In particular, the audience for these practices is intended to include organizations that provide cryptographic standards and protocols and enterprises that develop, acquire, implement, and service cryptographic products. This effort complements NIST's postquantum cryptography standardization activities.

Project Abstract

The initial scope of this project is to demonstrate the discovery tools that can provide automated assistance in identifying where and how public-key cryptography is being used in hardware, firmware, operating systems, communication protocols, cryptographic libraries, and applications employed in data centers whether on-premise or in the cloud and distributed computer, storage, and network infrastructures. The audience for the project includes developers of products that use public-key cryptographic algorithms, as well as product integrators, customer organizations that acquire or configure these products, and bodies that standardize protocols that employ or are dependent on public-key cryptographic algorithms.

The recommended project will engage industry in demonstrating use of automated discovery tools to identify all instances of public-key algorithm use in an example network infrastructure’s computer and communications hardware, operating systems, application programs, communications protocols, key infrastructures, and access control mechanisms. The algorithm employed and its purpose would be identified for each affected infrastructure component.

Once the public-key cryptography components and associated assets in the enterprise are identified, the next element of the scope of the project is to prioritize those components that need to be considered first in the migration using a risk management methodology informed by “Mosca’s Theorem” and other recommended practices.

Finally, the project will provide systematic approaches for migrating from vulnerable algorithms to quantum-resistant algorithms across the different types of assets and their supporting underlying technology.

It is critical to begin planning for replacement of hardware, software, and services that use public-key algorithms now so that the information is protected from future attacks.

Post-Quantum Cryptography: the Good, the Bad, and the Powerful

This video featuring NIST’s Matthew Scholl emphasizes how NIST is working with the brightest minds in government, academia, and industry from around the world to develop a new set of encryption standards that will work with our current classical computers—while being resistant to the quantum machines of the future.
