YYC delivers tailored cryptographic solutions?ranging from Post-Quantum Cryptography (PQC) and Zero Trust cyberdefense systems to enterprise blockchain wallet infrastructures and real-world O2O store management SaaS (EchoQR).
High-performance defense systems engineered against quantum threats and advanced intrusion
Secures national and enterprise data communications against quantum attacks through Q-Bridge virtual appliances using Lattice-based Cryptography (LWE) and NIST-standard PQC algorithms.
Powered by an Immutable OS and eBPF kernel packet isolation engine, immediately blocking Zero-Day intrusions and volumetric DDoS attacks directly at the kernel level.
Implements HSM-grade key lifecycle management algorithms (Soft HSM) along with IUWT tokens?a proprietary next-generation authentication standard engineered to replace legacy JWT.
Enterprise Web3 infrastructure backed by verified cryptographic key management algorithms
A high-security HD Wallet architecture supporting Solana, Tron, Ethereum, and other major mainnets. Secures the entire deterministic key derivation process from seed generation to key management within an encrypted kernel.
An institutional-grade digital asset settlement and exchange engine featuring strict privilege separation, multi-signature security modules, and immutable ledger integrity.
Proven technical assets spanning from foundational cryptography research to commercial deployments
Proprietary implementations of NIST PQC, LWE, Soft HSM, ECC/RSA Hybrid Cryptography, and the IUWT token issuance framework.
Linux Kernel eBPF packet filtering, Read-Only Immutable OS, and high-availability HAProxy L7 load balancing architectures.
Enterprise HD Wallet, SPL-Token infrastructure, OTC Exchange Engine, and EchoQR No-App O2O SaaS Platform.
