Real-time images are challenging to process with conventional technologies because they include a diversity of information with significant prolixity, high correlation among neighboring pixels, and high uncertainty due to sensor noise and environmental conditions. Therefore, the present work focuses on the secured transmission of real-time satellite images with a high Signal-to-Noise ratio. In this work, we have developed a novel hybrid encryption method that combines a six-dimensional (6D) hyper-chaotic system with the BB84 quantum key distribution (QKD) protocol for secure and efficient image transmission. The hyper-chaotic system enhances pixel scrambling and diffusion, reducing correlations in the image data, while BB84 ensures secure key exchange during transmission over Free Space Optics (FSO) channels. The integration of a 6D hyper-chaotic system with BB84 QKD protocol is capable of transmitting multichannel information in a single secured channel. The proposed technique is corroborated using a set of satellite images, as satellite images possess highly correlated information. In the proposed model, the original satellite images are taken for Gunupur, Odisha during the period of November 22, 2023, to January 23, 2024. These images’ information is confused by the hyper-chaotic system. Then, the permuted images are diffused to generate the scrambled image using the BB84 protocol. On the receiver side, the same information is recovered with reduced information loss using the proposed receiver module, which consists of an optical hard limiter followed by a low pass filter. The performance of the proposed scheme is tested via various quantitative assessments including entropy, mutual information, histogram, cross-correlation, and differential attack analysis. Performance metrics reveal robust security and high-quality reconstruction, achieving an entropy of 7.9976, a &lt;span&gt;&lt;math&gt;&lt;mrow&gt;&lt;mi&gt;P&lt;/mi&gt;&lt;mi&gt;S&lt;/mi&gt;&lt;mi&gt;N&lt;/mi&gt;&lt;mi&gt;R&lt;/mi&gt;&lt;/mrow&gt;&lt;/math&gt;&lt;/span&gt; of 8.9967, and a &lt;span&gt;&lt;math&gt;&lt;mrow&gt;&lt;mi&gt;B&lt;/mi&gt;&lt;mi&gt;E&lt;/mi&gt;&lt;mi&gt;R&lt;/mi&gt;&lt;/mrow&gt;&lt;/math&gt;&lt;/span&gt; of 0.1111 for the Pepper image.
