Abstract

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.

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

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.

Research on Secure Delivery of Quantum Key Based on Tickets

Yan Feng, Sijiang Xie, Nian Liu +1 more

The Quantum Key Distribution (QKD) network faces challenges in ensuring the confidentiality, integrity, and authenticity of quantum keys during the process of delivering quantum keys from the QKD network to the user application. To address these issues, a quantum key secure delivery scheme based on tickets is proposed. There are four types of tickets in the scheme: the user ticket, which is used for authenticating the identity of the user application; the access ticket, which is employed for granting access to the end-to-end key; and the publishing ticket and subscribing ticket, which are utilized for authorizing access to the group key. Additionally, a security mechanism based on symmetric cryptography for transmitting quantum keys is also proposed. It is used to protect the confidentiality, integrity, and authenticity of key data when quantum keys are transferred from the QKD network to user applications. Security analysis indicates that this scheme can effectively resist common attacks such as impersonation and man in the middle. Furthermore, by employing Secure Sockets Layer/Transport Layer Security (SSL/TLS) to establish a secure channel for the interactions between the user application and the Quantum Key Service (QKS), this scheme provides dual protection for the quantum key delivery process. This approach effectively mitigates potential security threats and enhances the overall security of the process.
