🚀 TraplessPKE — A New Direction for Post-Quantum Cryptography
How I designed a cryptographic system that abandons algebraic structure and survives quantum attacks

❓ What Is TraplessPKE?
TraplessPKE is a quantum-safe cryptographic system I designed to achieve:
- ✅ Public-Key Encryption
- ✅ Message-Bound Digital Signatures
- ✅ Zero reliance on lattices, primes, elliptic curves, or algebraic traps
- ✅ Compatibility with hardware and embedded systems
- ✅ Epistemic defense: validation is impossible without a secret — not just hard
🧠 What Makes It Different?
Unlike NIST-style PQC schemes based on algebraic hardness (like LWE, lattices, or codes), TraplessPKE is:
A structure-free cryptographic scheme based on entropy, filtering, and deliberate ambiguity.
Core principle:
You cannot break what you cannot recognize.
There is no structure to invert. No equations to solve. Only filtered meaning for those with the key.
🔐 How It Works (Simplified)
TraplessPKE uses:
- A Selector Map — links messages and ciphertexts via a common label space
- A Public Predicate — filters plausible ciphertexts
- A Trapdoor — blinds inputs via XOR masking
- A Hash-Bound Signature — cryptographically binds message + trapdoor
All operations are constant-time and linear-space.
No discrete logs. No modular arithmetic. No vectors.
📐 Use Cases
- Post-Quantum Secure Messaging
- Digital Signatures that can’t be reused or transferred
- Identity-bound credentials (ZK-friendly)
- Hardware authentication in constrained devices
- Defense systems where no cryptographic oracle or structure must exist
💡 Why I Built It
After two decades in banking risk and compliance, I saw firsthand how security often depends on assumptions that attackers eventually break. Quantum computing accelerates that collapse.
TraplessPKE is my answer:
A non-invertible surface designed to survive even when quantum attackers arrive — because there’s no algebra to attack.

“Security through ambiguity. Access through design. Meaning for those who are allowed.”
