This study aims to increase security during the transition period against the threats posed by quantum computers to existing cryptographic systems. Since it will take time for post-quantum cryptography standards to become fully applicable, especially asymmetric encryption methods face serious security risks. In this context, a hybrid encryption method that is more resistant to quantum computer attacks is proposed in the study. The proposed method aims to increase the security of asymmetric algorithms by using pre-shared symmetric key (PSK). In this approach, key distribution is made secure by using symmetric encryption algorithms resistant to quantum attacks such as AES-256. Thus, existing systems gain temporary protection against quantum threats and the transition process is managed more securely. This study examines the integration of symmetric and asymmetric encryption methods, evaluating the performance and potential security risks of the hybrid approach. It is aimed that the proposed method will contribute to the modernization of national and international cryptographic infrastructure and provide a critical Intermediate solution in the transition process to the post-quantum era.

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.

This paper explores the potential impact of quantum computing in several fields, including medicine, finance, cybersecurity, cryptography, high-performance computing and hacking. Quantum computing has the potential to revolutionize these fields by providing significant advancements in processing power, enabling the development of new algorithms and computing methods that were previously impossible with classical computing. The paper explores the potential risks of quantum computing in the context of hacking, as quantum computers can potentially break through existing security systems and create new threats to privacy and security. Quantum computing has the potential to break through current encryption methods and develop new, more secure encryption techniques. High-performance computing can benefit from quantum computing through faster simulations and optimization of complex systems. In the field of medicine, quantum computing can be used to accelerate drug discovery and personalize medicine by simulating molecular interactions at the atomic level. Finally, in finance, quantum computing can be utilized for portfolio optimization, risk management, and algorithmic trading. This paper concludes that quantum computing has immense potential for improving various fields, but it is important to consider the associated risks and challenges. Moreover, there is a need for further research and development in areas such as post-quantum cryptography, algorithm development and cybersecurity. The potential of quantum computing and its intersection with other technologies highlight the long path towards classical computing's maturation.
