At present a majority of computer and telecommunication systems requires data security when data is transmitted the over next generation network. Data that is transient over an unsecured Next Generation wireless network is always susceptible to being intercepted by anyone within the range of the wireless signal. Hence providing secure communication to keep the user's information and devices safe when connected wirelessly has become one of the major concerns. Quantum cryptography algorithm provides a solution towards absolute communication security over the next generation network by encoding information as polarized photons, which can be sent through the air security issues and services using cryptographic algorithm explained in this chapter.

Every attempt to access to the Internet through a Web browser, email sent, VPN connection, VoIP call, instant message or other use of telecommunications systems involves cryptographic techniques. The most commonly applied technique is asymmetric cryptography, which is generally executed in the background without the user even being aware. It establishes a cryptographic code based on the computational complexity of mathematical problems. However, this type of cryptography, which is widely used in today’s telecommunications systems, is under threat as electronics and computing rapidly develop. The development of fifth-generation cellular networks (5G) is gaining momentum, and given its wide field of application, security requires special attention. This is especially true faced with the development of quantum computers. One solution to this security challenge is to use more advanced techniques to establish cryptographic keys that are not susceptible to attack. An essential part of quantum cryptography, Quantum Key Distribution (QKD) uses the principles of quantum physics to establish and distribute symmetric cryptographic keys between two geographically distant users. QKD establishes information-theoretically secure cryptographic keys that are resistant to eavesdropping when they are created. In this paper, we survey the security challenges and approaches in 5G networks concerning network protocols, interfaces and management organizations. We begin by examining the fundamentals of QKD and discuss the creation of QKD networks and their applications. We then outline QKD network architecture and its components and standards, following with a summary of QKD and post-quantum key distribution techniques and approaches for its integration into existing security frameworks such as VPNs (IPsec and MACsec). We also discuss the requirements, architecture and methods for implementing the FPGA-based encryptors needed to execute cryptographic algorithms with security keys. We discuss the performance and technologies of post-quantum cryptography, and finally, examine reported 5G demonstrations which have used quantum technologies, highlighting future research directions.
In this modern era, when data communication is a necessity of life, data secrecy and privacy is very important. The concern increases when we communicate over insecure wireless channels because they are vulnerable to various security attacks. The expectation from cryptography is to deliver safe and reliable communication. With the emergence of quantum computers, we can say that quantum computers can perform cryptanalysis calculations much better in comparison with existing system. Quantum computers can crack all the existing security algorithms and protocols. Keeping this in mind, it is the need of the hour to develop new procedures for data security so that intruders remain surprised. So in this paper we want to discuss these issues in brief with some solutions to overcome the related challenges.
Security knowledge is one of the foremost challenges in the present day. When the topic is about Information security, the concept of cryptography comes into the picture. Every day, people and organizations use cryptography to maintain the confidentiality of their communications and data as well as to preserve their privacy. Today, one of the most successful methods used by businesses to protect their storage systems, whether at rest or in transit, is cryptography. Yet, cryptography is an effective technique to secure the data, the modern technology can break the cryptographic techniques. But some data encryption algorithms are several times stronger than today's conventional cryptography and can be constructed using quantum computing. They are "Quantum Cryptographic Algorithms ". Quantum cryptography uses the rules of quantum physics instead of classical encryption, which is based on mathematics, to protect and transmit data in a way that cannot be intercepted. Quantum key distribution is the greatest illustration of quantum cryptography and offers a safe solution to the key exchange issue. The proposed work deals with quantum cryptography and mainly focuses on how the quantum cryptographic algorithm is more secure than traditional cryptography.
Security is crucial for wireless communication networks, especially as quantum computing advances rapidly. It won’t be long before quantum attacks become feasible, potentially crippling large wireless networks within minutes. Current methods for securing connections and transactions—such as keys, certificates, and data—could be compromised by quantum computers. One concern is the use of fake base stations with stronger signal strengths to lure users into connecting with them in wireless communication network. A quantum-powered attacker could easily break traditional encryption algorithms and launch various attacks almost instantly. An example of this is the "bidding down" attack, where an attacker convinces both the user and network entities that security features are not upheld, despite their actual presence. This type of attack exploits the security weaknesses of older mobile networks. This paper explores security advancements and challenges related to contemporary public key cryptography, including RSA algorithms based on factorization and discrete logarithm problems with Diffie-Hellman and Elliptic-Curve Cryptography (ECC). While these methods provide adequate protection today, quantum computers could potentially break these algorithms or weaken cryptographic keys and hashes within minutes. Quantum cryptography, or quantum-resistant cryptography, objectives to develop algorithms and protocols resilient to quantum computing threats. This paper examines security vulnerabilities in wireless communication networks, focusing on key confirmation and authentication mechanisms. We propose a robust authentication and key agreement protocol for 5G networks using quantum-resistant cryptography. Our proposed protocol, verified with a verification tool, enhances the security of the authentication and key agreement procedures in wireless communication networks.
