Abstract Information security in communication networks is a persistent problem and essentially requires the usage of encryption methods. Quantum computing was first used to break encryption codes in the latter half of the 20 th century with the introduction of the SHOR algorithm. Though the recent developments in QC capabilities have increased confidentiality, integrity, and availability of networks by protecting them against passive attacks like eavesdropping yet the transformation of classical to quantum computation can bear catastrophic implications as it has the potential to put the currently secure methods of transactions in jeopardy. This paper aims at the evaluation and comparison of traditional cryptographic techniques by the application of a SWOT framework. It takes up an exploratory study of the advanced quantum computing capabilities that can pose a massive risk to network security. The various security enhancements that can be adopted in data transmission to curtail these risks post-quantum are also discussed.

"THE EL-RAKHAWI DOCTRINE OF QUANTUM SOVEREIGNTY" by Dr. Mohamed Kamal Arafa El-Rakhawi presents a definitive, mathematically rigorous framework to secure global digital infrastructure against the imminent threat of quantum computing. As "Q-Day" approaches, classical cryptography (RSA, ECC) will collapse, risking catastrophic breaches across finance, healthcare, and national security. This doctrine provides a comprehensive five-part roadmap: analyzing the quantum threat, implementing NIST-standardized Post-Quantum Cryptography (PQC) like CRYSTALS-Kyber and Dilithium, deploying Quantum Key Distribution (QKD), and redesigning internet architecture to be quantum-native. Crucially, it proposes the El-Rakhawi International Treaty on Quantum Sovereignty, mandating a coordinated global migration to quantum-secure systems by 2035. This actionable blueprint ensures a proactive transition, transforming an existential cyber vulnerability into a foundation for resilient, sovereign, and future-proof digital security for all humanity.

"The rapid advancement of quantum computing poses a significant threat to the cybersecurity of our increasingly digitized world. As quantum computers become more powerful and accessible, they have the potential to break many of the cryptographic algorithms that currently secure our sensitive data, financial transactions, and critical infrastructure. This looming “quantum threat” has far-reaching implications for individuals, organizations, and nation-states, as it could lead to widespread data breaches, economic disruption, and compromised national security. Despite the growing recognition of this risk, existing legal and regulatory frameworks are largely unprepared to address the unique challenges of quantum-enabled cyber threats. Moreover, the geopolitical implications of the quantum revolution are complex and multifaceted, with the potential to reshape the global balance of power and exacerbate technological inequalities. To mitigate these risks and promote quantum readiness, there is an urgent need for the international community to develop new legal frameworks and cooperative mechanisms that span technical, economic, legal, and political domains. This article provides an interdisciplinary analysis of the quantum threat to cybersecurity, examines its potential impacts across various sectors and international relations, and offers policy recommendations for developing a comprehensive global governance framework. By proactively addressing this challenge through multi-stakeholder collaboration and quantum-resistant solutions, we can work towards a more secure and resilient digital future in the face of this transformative technology.
