Abstract

The aim of this paper is to analyse the use of quantum cryptography
within PPP. We propose a solution that integrates quantum key
distribution into PPP.

Improving TLS Security By Quantum Cryptography

Mohamed Elboukhari, Mostafa Azizi, Abdelmalek Azizi

Quantum Cryptography or Quantum Key Distribution (QKD) solves the key distribution problem by allowing the exchange of a cryptographic key between two remote parties with absolute security, guaranteed by the laws of quantum physics.Extensive studies have been undertaken on QKD since it was noted that quantum computers could break public key cryptosystems based on number theory.Actually, the progress of research in this field allows the implementation of QKD outside of laboratories.Efforts are made to exploit this technology in the existing communication networks and to improve the performance and reliability of the implemented technologies.Some research is in progress for the integration of QKD with the protocols in different layers of OSI model.The examples of such research effort are the integration of QKD in point-to-point protocol (PPP) OSI layer 2 and the integration of QKD with IPSEC at OSI layer-3.All these works are moving towards the utilization of QKD technology for enhancing the security of modern computing applications on the internet.In this paper, we present a novel extension of the TLS protocol based on QKD.We introduce a scheme for integrating Quantum Cryptography in this protocol.Our approach improves the security of the process of authentication and data encryption.Also, we describe an example to illustrate the feasibility of our scheme's implementation.

Enhancing ip security by integrating quantum key distribution into communication processes

Mohamed Ali Sfaxi, Solange Ghernaouti-Hélie, G. Ribordy +1 more

The applications of quantum cryptography are linked to telecommunication services that require very high level of security. Quantum cryptography could be integrated in various existing concepts and protocols to secure communications. One of the possible use of quantum cryptography is within IPSEC or IPv6. The aim of this paper is to analyse the use of quantum cryptography within IPSEC to secure communications and to present the estimated performances of this solution. In this paper, we introduce basic concepts in quantum cryptography, we propose a solution that integrate quantum key distribution into IPSEC. A performance analysis is done to demonstrate the operational feasibility of this solution.

QKD Technology For High Performance Computing And Wireless Network

S Jonisha, Sureka

: Abstract - Quantum Key Distribution (QKD) is a point to point secure key generation technology which provides unconditional security. To exploit the security of QKD for large scale practical communication, it must be used in a network fashion. BBN DARPA quantum network and SECOQC network of secrets are the examples of such networks. Research is also in progress for the integration of QKD with the protocols in different layers of OSI model. Integration of QKD in point-to-point protocol (PPP) OSI layer 2 and the integration of QKD with IPSEC at OSI layer-3 are the examples of such research efforts. All these steps are moving towards the utilization of QKD technology for enhancing the security of modern computing applications on the internet. This paper presents a model for the exploitation of QKD security networks in high performance distributed computing applications, such as grid computing.
