Abstract

This Recommendation provides cryptographic key-management guidance. It consists of three parts. Part 1 (this document) provides general guidance and best practices for the management of cryptographic keying material, including definitions of the security services that may be provided when using cryptography and the algorithms and key types that may be employed, specifications of the protection that each type of key and other cryptographic information requires and methods for providing this protection, discussions about the functions involved in key management, and discussions about a variety of key-management issues to be addressed when using cryptography.
