Abstract

The need for communications networks is quite evident in the world today, multicasting has becomes a major way of transferring digital data to huge number of audience. The advantages of multicast in multi-party communications, such as saving bandwidth, simplicity and efficiency, are very essential for new services that combine voice, video and text over Internet. It has many applications in online multimedia and sensor networks and so on. The multicast networks distribute sensitive or private information, therefore they must be provided via secure communication channels. In this paper, the security of multicast network has been reviewed. A method has been presented to improve the security of multicast network (SMN) using quantum key distribution (QKD) network. This technique protected multicast network against internal and external impersonation. The QKD has been added to multicast network architecture to generate the secure keys. The keys are in the authentication and encryption processes. The proposed scheme aimed to provide a secure end to end communication for multicast network.

Multicast network security using quantum key distribution (QKD)

Sellami Ali, Omer Mahmoud, Aisha A. Hasan

We reviewed the confidentiality and authentication for multi-party applications. A conceptual model of a secure multicast network has been presented by adding a quantum key distribution (QKD) network to its architecture. The model is divided into three phases, the first phase, QKD network generate secure keys to encrypt not only data but also authentication process. The second phase, authentication making sure that no one except the legitimate user receive the message and making sure that nobody except the legitimate sender writes or modifies it. In the last phase, Multicast network encrypt the data by secure key and send it to receivers. The proposed scheme amid to provide a secure end to end communication for multicast network.

Secured IPsec Multicast Architecture Based on Quantum Key Distribution

Ahmed Farouk, Magdi Zakria Fatma Omara

Multicasting reveals to the delivery of a message or information from one source to multiple recipients simultaneously through a single transmission channel. Securing the transmitted multicast information can be achieved through IPsec multicast architecture. The process of IPsec involves the sender and destinations to agree on IPsec keys. These keys are used for protection transmitted information among communicated peers over IPsec network. IPsec depends on classical algorithm for key generation and distribution. These algorithms proved their conditional security which means intruder can break the algorithm and intercept the communication process. In this paper, a new IPsec multicast architecture is proposed. The proposed architecture is divided into five main processes. The most important process is key generation and distribution. The key generation and distribution through IPsec multicast network is achieved using quantum algorithms. Quantum keys proved their unconditional security according to their physical characteristics. Sender and receivers communicate through two channels which quantum and classical. Encryption and decryption processes depend on agreed quantum keys and classical cryptographic algorithms. IPsec depends on quantum key distribution for creating keys for IPsec security associations. The confidentiality and authentication of proposed architecture is analyzed

An Introduction to Cryptosystem for Multicast Quantum Based Network

Ahmed Farouk, Fatma A. Omara, Magdy Zakaria

Most existing realizations of quantum key distribution (QKD) are point-to-point systems with one source transferring to only one destination. Growth of these single-receiver systems has now achieved a reasonably sophisticated point. However, many communication systems operate in a point-to-multi-point (Multicast) configuration rather than in point-to-point mode, so it is crucial to demonstrate compatibility with this type of network in order to maximize the application range for QKD. Although encryption algorithms can be used to secure transmitted messages among group members, there are many security aspects for designing a secured multicast cryptosystem are needed to investigate. The most important aspects of multicasting are key generation and management. The researchers have proposed several approaches for solving problems of multicast key distribution and management. Therefore, we proposed four different architectures for implementing a multicast quantum key distribution with supportive protocols for generating and securing the transmitted messages among the communicated participants.

Enhancing Data Security in Transmission Through Quantum Key Distribution in Cryptography

Sulakshana Sagar Malwade, Shilpa Choudhary, Santosh H. Lavate +3 more

As the world becomes more computerized, keeping data transfer safe has become very important. Quantum computers and other strong computers have the ability to break classical encryption methods, even though they are widely used. Quantum Key Distribution (QKD) is a new way to protect data. It uses quantum physics to make sure that the sharing of cryptographic keys is safe. The aim of this study is to look into how QKD can be used to improve the security of data transfer. The suggested method combines QKD with current encryption standards to create a safe and effective way to send data. The method includes setting up a key sharing system based on QKD and then using symmetric encryption algorithms to keep the data being sent safe. The system is tried in different communication settings to see how well it protects against spying and "man-in-the-middle" attacks. The study's results show that QKD greatly improves the safety of sending data by keeping the cryptography keys secret. The results show that QKD has the potential to stop people from getting in without permission and find any attempts to change the keys while they are being sent out. The table below shows performance numbers that show how well QKD works in real-world situations. It shows how well communication speeds and security measures compare.

Securing SDN Communication through Quantum Key Distribution

Marian Hanashiro Rempola, Andrew D. Smith, Yan Li +1 more

Software-Defined Networking (SDN) is an emerging networking paradigm that decouples the control and data plane in order to enable programmable and flexible networks, optimizing its applications and advancing computer systems. It does so through its architecture, a key part of which is a centralized network management through open interfaces that revolutionizes the way in which networks are designed and makes them more agile and versatile to the evolving needs of modern and future applications services. This also means, however, that there is now a centralized point of attack that is a major vulnerability, threatening the security of the entire network. With such an advanced network paradigm, it requires a security system that will mitigate these risks and warrant long-term security. In attempts to allow secure communications within the network, this research proposes the implementation of Quantum Key Distribution (QKD), leveraging quantum mechanics to secure the network against any computational advancements in the future. QKD is a recent cryptographic system that includes a traditional-computational channel and a physical-quantum channel to generate and distribute keys between parties. It uses the principles of quantum mechanics including entanglement and superposition to ensure that the physical layer cannot be compromised computationally. QKD provides confidentiality and privacy of information and communication. Moreover, it is resistant to technological advancements. The implications of QKD significantly enhance SDN security through its protection against attacks, efficient key distribution, reliable network orchestration, and data integrity, creating an architecture that establishes stable communication channels that are resistant to cyber threats.
