A novel chaotic system based on coupled map lattice and its application in HEVC encryption

Area of Science:

• Computer Science
• Information Security
• Cryptography

Background:

• Traditional cryptographic systems are inadequate for large-volume video data due to its redundancy and relevance.
• Existing chaotic systems face challenges in meeting the demands of modern video encryption standards like HEVC.

Purpose of the Study:

• To introduce a novel chaotic system for secure and efficient video encryption.
• To apply this system to High Efficiency Video Coding (HEVC) for enhanced data protection.

Main Methods:

• Development of the logistic-iterative chaotic map with infinite collapses-coupled map lattice (L-ICMIC-CML) system.
• Generation of stream ciphers using L-ICMIC-CML for encrypting HEVC syntax elements.
• Evaluation of the encryption scheme's security, encryption time, and efficiency.

Main Results:

• The L-ICMIC-CML generated stream cipher demonstrates strong randomness, passing the SP800-22 Rev1a test.
• The proposed HEVC encryption scheme shows superior security, encryption time, and efficiency compared to other chaotic encryption methods.
• The system provides a safe and efficient solution for video encryption.

Conclusions:

• The L-ICMIC-CML system offers a robust and effective approach to video encryption.
• This novel method significantly improves upon existing chaotic system-based encryption schemes for HEVC.
• The developed video encryption system is both secure and computationally efficient.
