Meta-encryptor with multi-dimensional security architecture for wireless communications.

ABSTRACT: As wireless technologies advance and new applications emerge, ensuring secure and resilient networks is increasingly critical. Here, we propose a wireless security mechanism based on a meta-encryptor (ME) with low-complexity architecture leveraging the unique capability of information metasurface. ME controls electromagnetic waves in time, space, and frequency domains, and, combined with encryption strategies, enables elastic, complementary multi-dimensional security. Three advanced security dimensions are demonstrated: (1) directional beam secure transmission that confines transmissions to intended receivers; (2) dual channel direct and hybrid modulations that distribute information while complementing resilient cryptography; and (3) wide range frequency-hopping transmission to effectivel
