Abstract
A quantum attack-resistant system for processes of 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 processes of key exchange to perform quantum attack-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 exchange 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.
