Post-Quantum Cryptography
Advancing code-based cryptography through our CHN cryptosystem — engineered for long-horizon security and practical deployment.
QSPARC’s research centers on the CHN Cryptosystem (Can–Horowitz–Naig), a next-generation code-based framework designed for post-quantum resilience. Built on conservative assumptions and proven decoding theory, CHN delivers durable, performance-aware encryption suitable for large-scale infrastructures.
We emphasize verifiable security, transparent benchmarking, and clean interoperability. Each component of our cryptographic stack undergoes rigorous evaluation to ensure safety under quantum and classical attack models.
Focus Areas
CHN-Based KEMs & PKE
Developing and analyzing code-based encapsulation and encryption under the CHN framework for long-term confidentiality.
Decoder Optimization
Designing constant-time decoding algorithms, side-channel countermeasures, and performance-tuned implementations.
Hash-Based Signatures
Integrating XMSS and SPHINCS+ for stateless, conservative digital signatures.
Migration & Interoperability
Building hybrid deployment models and transition strategies for post-quantum rollout.
Publications & Research Notes
Our current manuscripts and technical briefs on the CHN cryptosystem are undergoing internal and peer review. To maintain research integrity and prevent premature citation, we do not list papers publicly.
Partners and collaborators may request access to preprints or validation data through our secure review process.
Standards & Collaboration
QSPARC contributes to the post-quantum ecosystem through open-source audits, interoperability testing, and standards engagement. Our focus is advancing code-based primitives — particularly the CHN framework — toward scalable and trusted deployment.
We’re currently seeking collaborators for code review, benchmarking, and implementation alignment across industries.
