TrajectoryCrypt: Behavior-based encryption without traditional keys

https://github.com/YukiyamaShizuka/TrajectoryCtypt
1•YukiyamaShizuki•7mo ago

Comments

YukiyamaShizuki•7mo ago
I’ve just open-sourced a structural encryption system I call TrajectoryCrypt. It's not an algorithm in the conventional sense—it's a framework for how information exists.

Core idea:

Rearranged binary data is injected into logic gate networks under entropy noise;

The output vectors form a spatial path;

A function f(x) is fitted from this path and made public;

Decryption isn’t about guessing keys—it’s about matching the original trajectory: Tangents, projections, and behavior-specific deviation.

It creates encryption as a path memory, not as a mathematical secret.

Source and whitepaper are public. Non-commercial usage is free; commercial use requires a license.
