Abstract

By relying upon the laws of quantum physics, quantum cryptography is reaching an extremely high level of security guarantee. It allows establishing a secret and perfectly random key material between two network nodes. It improves the contemporary cryptographic methods based only on computational security by integrating a quantum cryptographic solution. Since quantum technology becomes an attractive prospect, our overriding objective is to provide a quantum key agreement scheme that properly authenticates users in 802.11i networks. In this paper, we introduce a quantum scheme, for mutual authentication and key establishment for the integration within IEEE 802.11 networks towards absolute communication security. The key issued from the quantum algorithm authenticates the two endpoints and will be used for building the pairwise key and the group key hierarchies. To analyze the security of our approach, a formal verification of some security properties is performed using PRISM as a model checker tool.

Using Quantum Cryptography for Securing Wireless LAN Networks

Abolfazl Falahati, Hadi Meshgi

Quantum cryptography is an emerging technology in which two parties may simultaneously generate shared, secret cryptographic key material using the transmission of quantum states of light. Key distribution is the problem of classical cryptography algorithm, and tends to provide safe channel to transport key. Quantum cryptography could distribute key in quantum channel. Eavesdropper can not access to key on quantum channel. If Eve attack on quantum channel QBER increases and she is detected. While the application of quantum cryptography in fiber network has significant advances, research on the application of quantum cryptography in mobile networks is still premature. In this paper, we analyze the interests of using quantum technique for the distribution of encryption keys in 802.11 wireless networks. We also propose a scheme for the combination of quantum cryptography and 802.11i security mechanisms for the establishment of the PTK (Pairwise Transient Key).

High performance quantum cryptography architectures in IEEE 802.11 WLAN

Hongyang Ma, Shumei Wang

Quantum Key Distribution (QKD) is an ingenious application of quantum mechanics in information field. Wireless Local Area Network (WLAN) is gaining popularity as they are fast, cost effective, flexible and easy to use. They are, however, faced with some serious security challenges and the choice of security protocol is a critical issue for IT. In this paper, it analyzes the IEEE 802.11i wireless networking amendment with respect to data confidentiality, integrity, mutual authentication and availability. It provides novel high-performance quantum cryptography architectures in IEEE 802.11 WLAN by establishing a quantum key over a long distance. The supplicant sends qubits to the authenticator server by sharing EPR. Compared with the classical network architecture, it is proved in theory that an eavesdropper (Eve) invariably introduces errors within communication network if it wants to gain useful information. Quantum cryptography guarantees the security of the network.

Integration of a quantum scheme for key distribution and authentication within EAP-TLS protocol

Aymen Ghilen, Mostafa Azizi

The extensive deployment of wireless networks has led to a significant progress in security approaches that aim to protect confidentiality. The current method for exchanging a secret key within 'extensible authentication protocol-transport layer security' (EAP-TLS) protocol is based on public key infrastructure (PKI). Although this technique remains one of the most widely implemented solution to authenticate users and to ensure secure data transmission, its security is only computational. In other words, by the emergence of the quantum computer, the existing cryptosystems will become completely insecure. Improving the contemporary cryptographic schemes by integrating quantum cryptography becomes a much more attractive prospect since its technology does not rely on difficult mathematical problems such as factoring large integers or computing discrete logarithms. Thus, we propose a quantum extension of EAP-TLS that allows exchanging a cryptographic key and authenticating a remote client with unconditional security, ensured by the laws of quantum physics. PRISM tool is applied as a probabilistic model checker to verify specific security properties for the new scheme.

Integration and formal security analysis of a quantum key distribution scheme within CHAP protocol

Aymen Ghilen, Mostafa Azizi, Ridha Bouallègue

In a security context, to render a cryptosystem more resistant against man-in-the-middle and impersonation attacks, an authentication mechanism has to be considered. CHAP protocol (Challenge Handshake Authentication Protocol) is among the most widely spread authentication technique used within Local Area Networks. To offer greater robustness and privacy, we intend through our present paper to introduce a new quantum extension of CHAP that integrates quantum cryptography and takes advantage of its benefits such as eavesdropping detection, random secret key generation and unconditional security. A new scheme using a previously shared entangled qubits pairs with quantum unitary operators to ensure key agreement and mutual authentication is performed. To analyze the security of the proposed protocol, we use the PRISM tool as a model checker. We particularly focus on the security property of minimizing the quantity of information about the key that an enemy can obtain from applying a “man in the middle” attack. If we act on the parameters of the channel and the eavesdropper, we prove that this security property is affected by varying the efficiency of the channel as well as the power of the enemy. More interestingly, we show that the enemy could never be able to retrieve the value of the key.

Integration of a quantum authenticated key distribution scheme in the EAP-TLS protocol

Aymen Ghilen, Mostafa Azizi, Ridha Bouallègue

The expanded use of wireless networks has led to significant improvement in security approaches that aim to protect information. Providing secure communication for wireless local area network (WLAN) has become one of the prime concerns. The current standard for exchanging a secret key to authenticate users and ensure secure data transmission within EAP-TLS protocol relies on Public Key Infrastructure. This technique remains secure only in case of limited computational power of eavesdroppers. Thus, we propose a quantum extension of EAP-TLS which allows exchanging a cryptographic key and authenticating a remote client peer with absolute security, ensured by the laws of quantum laws.
