It first analyzes the original hybrid combiner construction and identifies security risks, then designs an enhanced scheme using the hybrid algorithm combiner by Nina Bindel et al. Formal analysis verifies unforgeability and 2-non-separability, while forward compatibility is achieved. Experimental results show higher key generation efficiency and signature verification efficiency, with signature verification reaching about 60% of the original under some algorithms. The scheme is implemented in the TLS 1.3 PSK mechanism to resist man-in-the-middle attacks while maintaining forward compatibility and stable time/storage overhead.","cbCaiiqyl1deY8zr","https://ap.wps.com/l/cbCaiiqyl1deY8zr","pdf",1552333,1,15,"English","en","# Introduction\n## Quantum impact on public-key cryptography\n## NIST post-quantum standardization\n## Related work and practical post-quantum protocol integration","[{\"question\":\"What motivates the proposed enhanced hybrid post-quantum digital signature scheme?\",\"answer\":\"The scheme targets threats to traditional public-key cryptography caused by quantum computing, and aligns with NIST’s post-quantum digital signature standardization efforts.\"},{\"question\":\"How does the paper improve the original OQS hybrid signature scheme?\",\"answer\":\"It studies the OQS hybrid construction, finds security risks, and then builds an enhanced scheme using the hybrid algorithm combiner approach proposed by Nina Bindel et al.\"},{\"question\":\"What security properties and performance results are reported?\",\"answer\":\"Formal analysis verifies unforgeability and 2-non-separability and ensures forward compatibility.
