Abstract Information security has become increasingly critical with the widespread development of wireless technologies. However, current information technologies predominantly rely on either software‐layer or physical‐layer encryption as standalone solutions, both which present fundamental constraints. In this article, a novel architecture for multi‐channel secret sharing and camouflage is proposed by combining software‐ mechanism based programmable metasurface. At software layer, one‐time pad (OTP) algorithm employs exclusive‐OR (XOR) operations dynamic keys predefined data to encrypt share secrets. physical metasurface spatially disperses shared messages through reconfigurable multi‐beam steering polarization control. Over‐the‐air experiments demonstrate that successfully realizes OTP sharing, capability unattainable static metasurface‐based systems. The robustness system also verified, underscoring its potential real‐world applications. Crucially, legitimate users must collaboratively combine all distributed encrypted recovery, whereas eavesdroppers intercepting individual channels obtain only non‐decryptable fragments, correspond data. This work synergistically integrates functionalities metasurfaces, offering transformative future highly secure networks storage architectures.
