Quantum-Based Encryption Model for Satellite Video Images: A Comparative Analysis
摘要
The paper presents a quantum model of encryption to offer a remedy to the increasing demand of data to be securely sent via satellite video images notably in such sensitive operations as custody and security. It is a hybrid between Quantum key distribution (QKD) protocol and visual cryptography, designing a computational encryption protocol providing image data with a highly secure encryption option against both classical and quantum attacks. Mathematical model based on photonic qubit is used to create secure keys, which further used to encrypt the video frames; red, green and blue (RGB) components. The algorithms like Shors or Grover quantum algorithm are incorporated to improve the key management and search efficiency in order to make the cryptographic process further robust. The quality and fidelity of the encrypted images are objectively accessed in terms of PSNR, SSIM, and MSE value. Moreover, there are statistical performance indicators, like NPCR and UACI, showing the model resistance to the differential attack and the noise attack. Comparison between this and traditional methods of encryption concludes that there is better performance in regards to security and computing power.
