The Department of Information Networks at the College of Information Technology – University of Babylon, held the defense of a master’s thesis presented by Alaa Marzah Abdul-Hamzah, entitled:
“Securing Data in Enterprise Network Communications Based on Chaotic Keys and Hybrid Lightweight Encryption Algorithms”, under the supervision of Asst. Prof. Dr. Noufal Turki Abis. The defense took place at 9:00 a.m. on Tuesday, September 9, 2025, at the college.

The thesis addressed the increasing challenges associated with securing data amid the growing reliance on digital communications, particularly in sensitive applications. It proposed an innovative approach that integrates dynamically generated chaotic keys with hybrid encryption systems (RC4 and PRINCE) to strengthen the security of communications between client and server.

The research findings indicated that the proposed system achieved high levels of confidentiality, integrity, and randomness of transmitted data, as demonstrated by entropy values and avalanche effect results that were close to ideal standards. Moreover, the study revealed that cloud-based implementation provided superior efficiency in memory utilization and statistical distribution, while local implementation significantly outperformed in speed, reaching transfer rates of over 600,000 KB/s using RC4, along with a notable reduction in CPU consumption. Although relatively slower, the PRINCE algorithm positively contributed to improving the statistical distribution quality.

The researcher emphasized that these outcomes highlight a critical practical trade-off between different computing environments: while cloud platforms ensure stronger statistical resilience and resource efficiency, local environments deliver maximum speed and higher processing efficiency.
