Single-pixel imaging shows great potential for parallel perception of multiple objects. However, existing methods face information security risks and lack effective user access control. In this Letter, we propose an access-controlled imaging method based on structured single-pixel illumination. The system introduces phase modulation equivalently into the measurement matrix by applying key-controlled spatial displacements to the projection patterns, without requiring additional modulation devices.

In the 5G network, the core network (CN) has undergone a major architectural change. That is, a flat service-based architecture is introduced into the control plane (CP) of CN to realize network openness, virtualization and cloudification [1]. In this architecture, the decoupling and integration among network functions (NFs) are realized through a modular framework, and NFs are implemented in software and run on commercial off-the-shelf hardware [2].
