Post-Quantum Cryptography — encryption algorithms resistant to quantum computer attacks
Quantum-safe encryption for India's defence and financial infrastructure — deployed as a transparent sidecar with zero hardware changes and zero application modifications. At 10% of the cost of hardware replacement.
A software-defined sidecar that wraps any existing system in quantum-safe encryption. Zero hardware changes. Zero application modifications. Deployable in under 15 minutes.
Full Solution DetailTactical radio, banking switch, or satellite terminal sends data normally — zero changes required.
Hybrid KEM: X25519 + ML-KEM-768. AES-256-GCM tunnel. Both algorithms must be broken simultaneously.
Receiving Vajra decrypts and delivers. Backend has zero awareness of the encryption layer.
Every parameter below is measurable, verifiable, and derivable from the source code. No estimates.
Security guarantee — adversary must break both ML-KEM-768 and X25519 simultaneously. Breaking one algorithm yields zero information about the session key.
Protecting classified military communications on HF radios, VSAT terminals, and SDRs against nation-state harvest attacks. Validated on Bharat-Pi Gen 2 (ARM Cortex-A55). Air-gap USB provisioning for forward-deployed units.
Securing SWIFT gateways, RTGS nodes, UPI switches, and CBS inter-bank networks. Stateless OCI containers — 2,000+ TPS, zero CBS application changes, RBI Cyber Security Framework aligned.
Ministry-to-ministry secure communications, NIC data centre interconnects, and G2G gateways. All key material generated and stored in India — full source code audit rights for DRDO and STQC.
State actors are harvesting encrypted data today for future quantum decryption. Vajra stops that now — without touching your hardware or applications. Prapti Labs is seeking defence, BFSI, and critical infrastructure design partners.
