An Introduction to Cryptosystem for Multicast Quantum Based Network

Abstract

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.

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. Therefore, this chapter proposed architecture for implementing a multicast quantum key distribution Schema. The proposed architecture is designed as a Multicast Centralized Key Management Scheme Using Quantum Key Distribution and Classical Symmetric Encryption. In this architecture, a secured key generation and distribution solution has been proposed for a single host sending to two or more (N) receivers using centralized Quantum Multicast Key Distribution Centre and classical symmetric encryption.

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.

Ahmed F. Metwaly, Magdi Z. Rashad, Fatma A. Omara +1 more

Most current implementations of quantum key distribution (QKD) are point-to-point systems with one sender transmitting to only one receiver. Development of these single-receiver systems has now reached a comparatively advanced stage. However, many communication systems operate in a point-to- multi-point (multiple-receiver) 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. In this paper, we suggest a proposed architecture of Point-to-Multipoint QKD (QKDP2MP) Systems and bow it will present in terms of QBB and Quantum layered Architecture.

Enhancement of multicast network security

Sellami Ali, Omer Mahmoud, Zaharah Wahid +1 more

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.

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

Design of Cryptosystem Architecture Based on Quantum Key Distribution

Weijia Xue, Wang Congli, Jingran Wang

Quantum key distribution (QKD) is a promising technique for addressing quantum threats. To enable easy-to-use cryptographic services based on QKD, we designed a cryptosystem that integrates classical cryptographic systems with key generation and distribution using a QKD network. The proposed cryptosystem comprises a centrally deployed cryptography management service platform and distributed key management systems. The paper presents the functional modules, main processes, interface design, and security requirements of the cryptosystem. This cryptosystem provides a secure and efficient way to offer cryptographic services for various business applications, such as identity authentication, application authorization and point-to-point or group session key distribution. By integrating QKD with classical cryptosystems, this approach can improve the security of traditional cryptographic systems by using the random and unconditionally secure keys generated by QKD. Furthermore, combining QKD with classical cryptographic systems can enhance the scalability of QKD and provide more efficient and cost-effective solutions for large-scale cryptographic services.
