Core Technology
QSPARC develops secure, performant implementations of the CHN Cryptosystem — a modern code-based framework for post-quantum encryption.
The CHN Cryptosystem (Can–Horowitz–Naig) underpins QSPARC’s post-quantum technology stack. It enables key encapsulation and public-key encryption that remain stable under quantum-scale adversaries while maintaining practical efficiency for today’s workloads.
Our work focuses on efficient decoders, predictable key handling, and simple hybrid integration paths. The result: conservative cryptography engineered for long-term reliability and deployability.
Projects & Tools
Private engineering efforts built around CHN.
CHN Core
Reference implementation of our CHN key encapsulation and encryption system. Currently private and under evaluation.
CHN SDK
Internal developer tooling for integrating CHN primitives into applications and testing environments.
Validation Harness
Automated benchmarking suite for decoding speed, failure-rate auditing, and reproducibility verification.
These components are currently in private testing. To participate in partner validation programs, contact our engineering team.
Platform Targets
Deployable and efficient across modern environments.
Server & Cloud
mTLS hybrids, certificate profiles, and high-performance key management for datacenter use.
Client & Applications
WASM and native bindings for encrypted messaging, key exchange, and session management.
Embedded & Edge
Optimized constant-time decoding and compact key representations for constrained devices.
Security & Validation
- Constant-time execution paths to prevent timing leaks.
- Side-channel audits for cache, EM, and fault resistance.
- Failure-rate evaluation through large-scale parameter testing.
- Reproducible builds & SBOM for supply-chain transparency.
- Decoder integrity validation across CHN parameter sets.
Interop & Standards
We align our CHN implementations with evolving post-quantum standards and hybrid frameworks. Ongoing work includes TLS, VPN, and secure messaging integration paths.
QSPARC invites collaboration with research groups and enterprises exploring conservative PQC deployments and cross-validation.
