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.
