As quantum computing technologies continue to advance, traditional cryptographic schemes based on discrete logarithm problems face increasing security challenges. This paper introduces a novel post-quantum digital signature scheme that combines the PORS approach with Verkle trees, achieving significantly smaller signature sizes compared to traditional Merkle-tree-based PORST constructions.

The proposed scheme reduces authentication overhead through constant-size vector commitment proofs while addressing the subset-resilience limitations of the original HORS signature family. The research contributes to ongoing post-quantum cryptography standardization efforts by offering a scalable and efficient signature solution that balances security, compactness, and verification performance.

This publication represents another important scientific achievement within our NATO SPS project activities focused on advancing next-generation cryptographic technologies for the post-quantum era.
