Overview Paper: Innovative Approaches to Key Management
Key management is an important part of building strong security and even quantum resilience for your organization, especially when implemented with high entropy keys. Indeed, NSA guidelines recommend the use of large, high entropy pre-shared symmetric keys and AES-256 for users who want to deploy quantum resistant systems.
This document shares eleven important guidelines to help define and implement your key management infrastructure and start to build that quantum resilience. They include key management best practices such as proper management of key lifecycles, replication of key material for high availability, as well as the appropriate use of full entropy random numbers, and developing the agility to integrate post quantum encryption algorithms as they become available.
