Unlike brute-force search or probabilistic quantum measurement, the method achieves decryption in a single engineered collapse. Hardware embodiments include optical photonic systems, neuromorphic processors, and resonant field architectures. Applications extend to RSA, Diffie-Hellman, elliptic curve cryptography, lattice-based post-quantum protocols, blockchain, and secure messaging frameworks. Proof-of-concept demonstrations on small instances, including factorization of $N=15$, illustrate feasibility at toy scale. Scaling to larger cryptosystems is envisioned through adaptive parameter control, resonance calibration, and experimental implementation.

Resumen de: WO2026006929A2

The invention relates to an identification module (1) for attaching to a physical product (18) and to a system for digitally verifying the authenticity of a physical product (18) using the identification module (1) and a blockchain (5). The identification module (1) has a transponder (2) which generates a transponder-specific physically generated PUF code (4). The transponder (2) is also configured to provide a communication with the blockchain (5) via the Internet using a blockchain communication interface (10). The PUF code (4) is combined with unique product information in order to form a blockchain-based security anchor (e.g. NFT) on a blockchain. After referencing the blockchain, a product-specific identification code correlating, at any time, to the physically generated PUF code (4) is thus produced in the blockchain. The product is authenticated in a user-friendly process, for example, via a verification platform (15) in the form of a browser-based web application. The exchange of data on the basis of the communication rule set facilitates, for example, the process of checking whether the PUF code stored on the blockchain matches a hash which is currently read by the transponder (and which should correspond to the PUF code). The web application then displays one of the possible results, e.g. "authentic", "manipulation risk", "forgery", in real time. The entire process is carried out solely on the browser without an app, without a wallet, and without a registration proc
