Area of Science:

• Optics and Photonics
• Information Security
• Materials Science

Background:

• Metamaterials offer advanced control over optical waves in spatial and spectral domains.
• Hyperspectral imaging enables multi-channel data acquisition, crucial for advanced applications.
• Traditional image encryption uses 1-to-1 transformations, which can be vulnerable to attacks.

Purpose of the Study:

• To propose a novel 1-to-n image encryption scheme for secure communication systems.
• To leverage metamaterials and hyperspectral imaging for enhanced data security.
• To develop a robust encryption method resistant to brute-force and statistical attacks.

Main Methods:

• A 1-to-n transformation scheme dispersing plain image data across 'n' cipher images.
• Utilizing metamaterials for optical wave manipulation across spectral channels.
• Analyzing key space growth and security against various attack vectors.

Main Results:

• The proposed scheme achieves a double exponential increase in key space size with the number of channels.
• Demonstrated security against brute-force and statistical sampling attacks.
• The multichannel scheme can be cascaded with existing 1-to-1 methods to further enhance security.

Conclusions:

• The 1-to-n encryption scheme offers superior security for image data transmission.
• Metamaterials and hyperspectral imaging provide a powerful platform for next-generation secure communication.
• This approach opens new avenues for secure data transmission in multi-wavelength imaging systems.
