PERFORMANCE OF QUANTUM BASED IMAGE SCRAMBLING CRYPTOGRAPHY USING QPQ-CD ON 5G NETWORK AUTHENTIFICATION KEY AGREEMENT

Telecommunication engineering

The QPQ-CD (Quantum and PostQuantum CipherKey Dynamic uses a dynamic key after the registration of the mobile at the 5G Network. The algorithm could be divided in two parts : The Quantum Cryptography and Post Quantum Cryptography. The Quantum Cryptography used Quantum Image Scrambling methods with the Red, Green, and Blue Component which are treated separately by the two algorithms QAT and QHT. They change only the position of the image pixel without changing the value of this. QAT and QHT use 2 method different : one is based on the permutation of the pixel position and the others is based on one the space-filling curveIn this article, the performance of the Quantum Cryptography using at the QPQ-CD is analyzed by the PSNR(Peak Signal to Noise Ratio), SSIM (Structural SIMilarity), NPCR(Number of Pixel exchange rate), UACI (Unified Average Changing Intensity), Correlation and the binary entropy. PSNR for the two methods is near than the value 8 which is a good visual quality visualThe SSIM and Correlation also offers a best parameter which is near zero. The image transformed by scrambling methods and originals are no similitude and no correlation. The NPCR give also a good performance because 99% of pixels changed in the image. But the UACI is not more than 20%. So, the intensity light of the new image doesn’t change with the maximum. The algorithm of the scrambling is not resistant to the attack physic using difference power analysis. The binary entropy is less than 50%. There are quite no disorder between the bits one and bit zeros. The QPQ-CD with evaluation of the Quantum Cryptography is simulated to Matlab and all curve for this is represented in this article. The QAT and QHT have quite a similar performance.
