Advanced Encryption Scheme based on AES for Moving Target Defense

An advanced encryption scheme leveraging AES (Advanced Encryption Standard) for Moving Target Defense (MTD) enhances cybersecurity by dynamically altering encryption parameters and keys. MTD aims to increase the complexity and unpredictability of a system's defense mechanisms to thwart potential attackers.

In this scheme, AES, known for its robustness and efficiency, serves as the foundation. Rather than using static encryption keys and parameters, the system periodically rotates AES keys and modifies encryption configurations. This dynamic approach ensures that even if an attacker compromises one set of keys, subsequent encryption sessions use different keys, making it challenging for adversaries to sustain attacks.

The scheme operates by employing a centralized or decentralized controller that orchestrates key rotation and parameter changes across the network or system. This controller may trigger key updates based on predefined conditions such as time intervals, system events, or detected anomalies indicating potential threats.

Furthermore, the AES parameters themselves can be varied, including key length, block size, and modes of operation, thereby further complicating attack vectors and increasing system resilience. Such adaptability not only fortifies data protection but also aligns with the principle of defense-in-depth by adding layers of security through dynamic cryptographic operations.

Key advantages of this approach include enhanced resistance against brute-force attacks, reduced vulnerability to cryptographic compromises, and improved compliance with cybersecurity best practices. By integrating AES with MTD principles, organizations can mitigate risks associated with static encryption methods and maintain data confidentiality and integrity in dynamic and evolving threat landscapes.

In conclusion, an AES-based encryption scheme for Moving Target Defense represents a proactive and sophisticated approach to cybersecurity, leveraging dynamic key management and encryption parameter variation to bolster the security posture of digital systems and networks.
