The Native-Signature Boundary in Post-Quantum Distributed Authorization
This paper defines the design trade-off between native and wrapper-based approaches to post-quantum threshold signatures—a key architectural decision for enterprises planning PQC migration of multi-party authorisation.

arXiv:2609.03547v1 Announce Type: new Abstract: Post-quantum signature migration poses a distinct systems problem when authorization is distributed among multiple parties. In native threshold signing, the signature algorithm may determine key generation, share state, preprocessing, interaction, combination, refresh, and recovery. Architectures that evaluate threshold policy outside the native signing relation can reduce this coupling, but their authorization evidence is not accepted by an uncha
Editorial Analysis
Enterprises planning post-quantum migration must choose between native threshold and wrapper approaches for distributed authorisation; this framework clarifies the security and performance trade-offs.
Include native-vs-wrapper threshold signing analysis in your PQC migration roadmap for any distributed authorisation system.
