This research establishes the existence of uncloneable encryption without relying on computational assumptions, offering a novel security bound of $\widetilde{O}(1/\lambda)$ based on quantum physics principles. The result, published in Nature Physics, provides a theoretical foundation for post-quantum cryptographic schemes that leverage physical unclonability rather than algorithmic hardness. For the tech community, this represents a significant shift toward hardware-intrinsic security models that could redefine long-term data protection strategies.
Uncloneable Encryption from Decoupling
arXiv:2503.19125v3 Announce Type: replace Abstract: We show that uncloneable encryption exists with no computational assumptions, with security $\widetilde{O}\left(\tfrac{1}{\lambda}\right)$ in the security parameter $\lambda$.
