Enhancing Satellite Security by Encrypting Video Data Directly on Payloads

The rapid expansion of low-Earth orbit (LEO) satellite constellations has underscored the need for secure video transmission in satellite communication systems.

Applications such as remote sensing, disaster relief, and secure information exchange rely heavily on video data, which is increasingly vulnerable to security threats like information leakage and data distortion.

To address these challenges, researchers have developed a novel approach to encrypting video data directly on satellite payloads using 1D chaotic maps.

Overcoming Challenges in Real-Time Encryption

Traditional encryption methods, such as DES, AES, and RSA, face significant hurdles in achieving real-time performance due to their computational complexity and the limited resources available on satellite devices.

The harsh environment of space also poses challenges, including power consumption and heat dissipation issues.

To overcome these obstacles, the new encryption scheme employs two novel 1D chaotic maps that are lightweight and efficient, making them suitable for real-time video encryption in resource-constrained satellite communication systems.

Satellite video communication framework and challenges of real-time video encryption on satellite payloads

The proposed algorithm simplifies the encryption process to a single XOR operation, reducing computational complexity and enhancing speed.

Implemented in C++ for high performance, the scheme also stores encrypted data in binary format to minimize storage time and ensure data integrity.

The use of bitwise XOR operations from the OpenCV library further optimizes the encryption process, providing hardware-accelerated operations for binary data.

According to the Report, this approach has been successfully tested on both Field Programmable Gate Array (FPGA) platforms and Raspberry Pi devices, demonstrating its feasibility and stability across different satellite edge devices.

Deployment and Validation

For the first time, a real-time video encryption algorithm has been deployed on a satellite, with experiments confirming its adaptability to the complex space environment.

Comprehensive statistical tests, including the NIST and DIEHARD suites, validate the robustness and security of the encryption system.

Timing and power consumption analyses conducted on the Raspberry Pi 4B show that the scheme can efficiently encrypt high-definition videos in real-time, making it a promising solution for secure data transmission in satellite communication systems.

This breakthrough enhances the security of satellite communications by providing a reliable and efficient method for encrypting video data directly on satellite payloads.
