Sectorization: Addressing the Shortcomings of HBS
This whitepaper introduces the basic ideas behind hash-based signatures (HBS), discusses their suitability to use in a firmware or code-signing application, and describes some of their limitations in a real-world setting in disaster recovery and survivability. It proposes the use of sectorization as a means of addressing some of HBS’ shortcomings.
High-quality entropy is an important cornerstone of security in an era of complex cloud computing deployments, machine intelligence, and the advent of quantum computers. This white paper walks you through the importance of entropy in the generation of cryptographic keys, why good entropy is difficult to create, and the role of NIST's entropy-as-a-service architecture.
