Abstract

One of the biggest concerns among cybersecurity professionals these days is the hype around quantum computing, its incomprehensible power, and its implications. The advancement in quantum computing has the potential to revolutionize our daily lives, but it can also completely break down the Internet as we know it. Mathematicians and physicists have developed algorithms based on quantum computing, which can change the Internet security paradigm. This article discusses quantum computing key concepts, with a special focus on quantum Internet, quantum key distribution, and related challenges.

Cybersecurity and Prevention in the Quantum Era

Abhinav Dwivedi, Gurmeet Kaur Saini, Usma Ibrahim Musa +1 more

Emerging future technologies such as Quantum computer is a serious threat to the privacy and security of user data and organizational security. The speed of outperforming classical computers is a major concern. If quantum computer at scale becomes real it will break current crypto systems such as TDS, DES, AES, etc. While quantum computing has the potential to significantly impact cybersecurity, there are still many challenges that need to be overcome and advancements to be made. One major challenge is producing enough fault-tolerant qubits, which are the basic units of quantum information, to fully utilize the computational power of quantum computers. There are also several key differences between quantum computers and the classical computers and smartphones that are commonly used today. Despite these challenges, quantum computing holds promise for revolutionizing various fields, including cybersecurity.

Quantum Cryptography: The Future of Internet and Security Management

Faisal Abbasi, Pawan Singh

In today’s world, cryptography techniques are used and implemented on the elementary method of finding the prime factor of large integer, which is said to be “Inevitable to Track”. But living in an era where nothing is impossible to achieve, so cryptographic techniques are exposed to both technologies’ advancement in computational power of machines and advancement in the fields of mathematics to break the notion that factoring of large integers into their prime is impossible. To cope up with the threat that cryptography will face is handled by fusion of physics into cryptography, leading to the evolution of Quantum Cryptography. It is one of the fast-growing fields in computer technology. In this paper, I am going to brief the concepts of Quantum Cryptography and how this technology has led to the development of the strategy of complete secure key distribution. The paper covers the loophole present in the modern cryptography techniques, the fundamental principle of quantum cryptography, its implementation in the real world along with the limitation faced in this field, and the possible future of quantum cryptography.
