Network Distribution of Remote Sensing Images Based on Multi-rank Security

With the development of remote sensing technology and network, a wide range of space information civilian use make remote sensing images security more and more attention. On the basis of the characteristics of large amount of remote sensing data but real-time transmission or access, a scheme of authorizing the use of remote sensing images based on multi-rank security through Internet distribution is proposed. The same remote sensing images data after encryption are distributed to different rank users, but different authorization users acquire different important degree information after decryption through their own different decryption keys. Experiment and theoretical analysis prove that the scheme has high confidentiality and high computing efficiency, and can meet the requirements of practical application.
