Abstract: A quantum computing-threat-resistant system for cryptography key exchange comprises a linear-space computing module, a manifold computing module, and a Banach-space computing module. The system implements the technologies of homotopy morphing and key cloaking for facilitating the key-exchanging processes to perform quantum computing-threat-resistant operations in a mathematics space which is different from the spaces that generic quantum attacks work on, and then retrieve the original key in a Hilbert space after the processes of key exchange. The system not only avoids quantum attacks on key-exchanging processes, but also avoids the defects of current PQC solutions, the vulnerability of the main streamed symmetric & asymmetric encryption systems, and the limitation of quantum key operation in a Hilbert space. Both legacy key solution and quantum key solution are provided and implemented without requiring expensive devices.
