This includes key identification, key serialization, and key compression. The purpose is to provide guidance such that the adoption of quantum-safe algorithms is not hampered with the fragmented evolution of necessary key management standards. Early definition of key material standards will help expedite the adoption of new quantum safe algorithms at the same time as improving interoperability between implementations and minimizing divergence across standards.
