The MEDINA Project Announces Defense-in-Depth Encryption Architecture and Open Challenge to the Quantum Computing Industry

April 15, 2026

The MEDINA Project today announces the public release of MEDINA, a defense-in-depth encryption architecture that adds architectural depth to proven symmetric primitives (AES-256, SHA3-256, HKDF).

What Was Built

MEDINA (Multi-layered Encrypted Deterministic Interlocked Nested Architecture) combines two entangled mechanisms into a two-factor symmetric encryption construction:

  • Matryoshka Chains — sequential, dependent encryption layers where each layer's key derives from the previous layer's output. This forces serial execution, preventing parallel brute-force attacks.
  • Blind Souk Routing — a SHA3-256 hash graph with a 2256 search space and no intermediate oracle feedback. Path verification requires completing the full decryption pipeline.

Open Challenge

The MEDINA Project has issued two public challenges:

  • "Break MEDINA" — an open challenge to any cryptographer, researcher, or team worldwide to find a weakness in the architecture.
  • "The Forever File" — a specific challenge directed at 12 leading quantum computing companies, including IBM Quantum, Google Quantum AI, IonQ, Rigetti, Quantinuum, and others, to decrypt a MEDINA-encrypted file using any quantum hardware or algorithm available.

V2 Hardening

The project has also released a V2 implementation hardening module addressing the six most common ways real-world cryptographic systems fail: weak randomness, key reuse, side-channel attacks, AES mode errors, key storage, and code bugs.

Licensing

MEDINA is released under the MOAL v1.0 license (proprietary). The code may be read, audited, and attacked — but not copied or redistributed.
