Hash-based signatures (HBS): suitability to use in a firmware, or code-signing application, and limitations in a real-world setting in regards to disaster recovery and survivability.

Sectorization: Addressing Hash-Based Signatures’ Shortcomings

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 regards to disaster recovery and survivability. All of this is in preparation for the introduction of the proposed use of sectorization as a means of addressing some of HBS’ shortcomings.
