A novel optical multi-image data protection schemebased on phase-truncated asymmetric ciphers and2D-CSCCM

Abstract Existing remote sensing platforms often overlook the security of the
remote sensing image acquisition process, creating opportunities for potential attackers
to exploit. To address this issue, this paper proposes a novel optical encryption
framework (ECC DPM) based on elliptic curves and phase truncation to ensure the
secure transmission of optical keys. Furthermore, an optical encryption scheme is
designed based on ECC DPM to enable synchronous secure encryption during the
remote sensing data acquisition stage, ensuring that remote sensing data remains in
a ciphertext state from acquisition to storage and distribution. Finally, the proposed
framework and encryption scheme are evaluated for security using a threat model and
simulation experiments. The experimental results demonstrate that the encryption
scheme effectively resists various statistical analysis attacks.
