The COMPANY

Security software designed for the quantum era

BLAZING A TRAIL TO THE FUTURE

Quantum Resistant Cryptographic Solutions (QRCS) Corporation is a deep-tech research company specializing in the design and development of sovereign post-quantum cryptography. QRCS builds the foundational technologies required to secure global digital infrastructure against emerging quantum and advanced classical threats. Its portfolio spans the entire cryptographic spectrum, from the low-level RCS and CSX stream cipher suites and the QSC cryptographic library, to advanced protocols for key distribution (HKDS, SKDP), tunneling and transport security (SATP, QSTP, DKTP), secure messaging (QSMP, PQS), distributed trust and anonymity systems (MPDC, AERN), and the Universal Digital Identity Framework (UDIF).

Every component is internally authored in MISRA-compliant C, engineered for constant-time operation, and backed by comprehensive ISO-style specifications. The technologies employ NIST-endorsed primitives including Kyber, McEliece, Dilithium, SPHINCS+, SHA-3, SHA2, AES, and ChaCha, and conform to leading models of authenticated key exchange and forward secrecy. Together, these assets form a coherent intellectual-property portfolio that addresses the complete life-cycle of post-quantum security, from primitive design to deployable protocol.

With a collection of patent-pending systems, transparent public codebases, and verified performance exceeding legacy standards, QRCS represents a unique opportunity for investors or acquirers seeking defensible intellectual property, regulatory alignment, and strategic entry into the rapidly expanding market for quantum-safe infrastructure.

The Details

Protocol suite overview

Core library plus specialized protocols for transport, identity, messaging, and secure tunnels

The QSC Library

The QSC library is a portable MISRA-aligned C library implementing symmetric ciphers, hash and MAC functions,  post-quantum ciphers and signature schemes, a complete sockets library, asynchronous threading, and a extensive set of support functions. Emphasizes deterministic lifecycles, constant-time discipline, secure memory handling, and cross-platform builds with reproducible tests and vectors.

Heirarchal Key Distribution System

HKDS provides quantum-safe keying without reliance on asymmetric primitives primitives. Built as a replacement for DUKPT, and designed for durable security properties using the SHA3 SHAKE XOF function and KMAC authentication, minimal assumptions, and straightforward implementation, with emphasis on verifiable hashing workflows and clear operational guidance.

The Post-Quantum Shell

PQS is a remote shell protocol using post-quantum primitives (e.g., Kyber for encryption, Dilithium for signatures) with SHA3 hashing and the RCS AEAD cipher for authenticated encryption. Incorporates strict message sizing, valid-time windows, and anti-replay checks across the key-exchange and packet flow.

Dual Key Tunneling Protocol

DKTP combines an asymmetric key exchange, and a pre-shared key. Uses Kyber or McEliece asymmetric cipher, Dilithium or SPHINCS+, and SHA3-512 for authentication. True 512-bit per channel post-quantum security makes DKTP the most powerful encrypted tunneling protocol in the world.

Quantum Secure Messaging Protocol

QSMP is a post-quantum framework for low-latency, end-to-end encrypted communication. It has 2 modes, SIMPLEX 256-bit secure server client, and DUPLEX, a 512-bit client to client encrypted tunnel. It uses lattice or hash-based asymmetric signatures in simplex or duplex modes, and McEliece or Kyber encryption, ensuring message integrity, forward secrecy, and resistance to quantum and classical attacks for secure, real-time transmission across distributed systems.

Quantum Secure Tunneling Protocol

QSTP is a post-quantum tunneling protocol providing authenticated, encrypted communication channels. It uses hybrid key exchanges, stream encryption, a lightweight root-anchored certificate scheme, and hash-based authentication to ensure confidentiality, integrity, and forward secrecy for secure data transport across modern network and infrastructure applications.

Symmetric Authenticated Tunneling Protocol

SATP is a symmetric post-quantum tunneling protocol that establishes encrypted, authenticated communication channels using pre-shared symmetric keys and nonce-based initialization. It provides confidentiality, message integrity, and replay protection, enabling high-speed, low-latency secure data exchange across trusted endpoints without requiring asymmetric cryptography or external key infrastructure.

Secure Key Distribution Protocol

SKDP is a post-quantum symmetric protocol for distributing session keys across trusted nodes. It employs authenticated encryption, nonce-based key rotation, and hash-derived key material to ensure confidentiality, integrity, and forward secrecy, enabling secure, lightweight key exchange in constrained or high-performance network environments.

Secure Infrastructure Access Protocol

SIAP is a post-quantum two-factor authentication system for secure infrastructure and device access. It uses a hardware key-tree token with a user passphrase to derive single-use symmetric keys, ensuring offline verification, forward secrecy, and deterministic, auditable authentication in critical embedded and enterprise environments.

Multi-Party Domain Cryptosystem

MPDC is a post-quantum Multi-Party Cryptosystem that establishes authenticated domains across servers, agents, and clients. It combines hybrid asymmetric and symmetric key exchange, deterministic policy enforcement, and hierarchical certification to ensure confidentiality, integrity, and coordinated governance for secure, federated, and large-scale network infrastructures.

Universal Digital Identity Framework

UDIF is a post-quantum identity and authentication architecture that unifies users, devices, and organizations under a cryptographically verifiable model. It employs hash-based identifiers, certificate chains, and secure messaging to ensure authenticity, privacy, and traceability across domains, supporting decentralized identity governance and interoperable trust infrastructures.

Authenticated Encrypted Relay Network

AERN is a post-quantum secure relay architecture enabling private, end-to-end encrypted communication across distributed nodes. It uses authenticated key exchange, encrypted route maps, and session resumption mechanisms to provide anonymity, integrity, and forward secrecy for secure routing, messaging, and data transport across decentralized infrastructures.
