This invention provides a method and apparatus for compressing and encrypting snapshots of multiple 3D color objects based on spatial division multiplexing. The method includes: generating an object beam and a reference beam based on a three-primary-color laser source, and generating multiple composite three-color parallel beams based on the object beam; illuminating each 3D color object and a random phase mask connected to each 3D color object with the multiple composite three-color parallel beams, respectively, and calculating the light field distribution of each 3D color object on the corresponding random phase mask plane; encrypting the light field distribution using each random phase mask, and generating an object light field on a detector plane based on the encrypted light field distribution; and generating an encrypted color hologram of multiple 3D color objects by interfering with the reference beam on the detector plane through the object light field and the reference beam. This method can significantly reduce the crosstalk effect during decoding of different encrypted objects, greatly reduce the leakage of object information, and significantly improve security.

This invention relates to the field of IoT security technology, and in particular to a secure authentication and encryption system for lighting equipment. The system includes a dynamic key hierarchical generation module, a hardware-level secure storage unit, and a multi-factor authentication module. The dynamic key hierarchical generation module generates multi-level dynamic keys based on an initial trust relationship; the hardware-level secure storage unit uses an independent security chip to achieve physical protection and logical isolation of sensitive data; and the multi-factor authentication module combines device fingerprints, user behavior characteristics, and timestamps for multi-level identity verification. This invention improves the security authentication and encryption capabilities of lighting equipment in an IoT environment, reduces the complexity of key management, enhances identity authentication efficiency and resistance to physical attacks, and provides an efficient and flexible security solution for smart home, industrial control, and other scenarios.
