A Framework for Stateful Digital Signatures with Post-Compromise Recovery — Cryptographic Commitment v2.0

Key Points

The aim is to establish a framework for digital signatures that remain secure even after exposure to vulnerabilities.
Describes a framework using cryptographic commitment techniques
Utilizes SHA-256 hash for verification
Includes a list of claim areas related to the technology
Presents a theoretical framework for improved digital signature security
Offers a method for verifying the integrity of confidential documents through hashing

Abstract

Cryptographic commitment (SHA-256 hash) for a confidential technical disclosure describing a framework for post-quantum digital signatures with post-compromise security (PCS). This document contains no technical details — only the SHA-256 hash of the confidential disclosure and an abstract list of 12 claim areas. The full document is held privately by the author and will be disclosed upon request for patent prosecution, litigation, or regulatory review. Verification: obtain the original document from the author and compare its SHA-256 hash with the one published herein.
