摘要

Abstract. Quantum Cryptography or Quantum key distribution (QKD) is new method that allows the secure distribution of a bit string, used as key in crypto-graphic protocols. Extensive researches have been undertaken on Quantum Cryptog-raphy since it was noted that quantum computers could break public key cryptosystems based on number theory. Quantum Cryptography offers uncondition-ally secure communication based on laws of quantum physics. Actually, there is a strong need of research to use this technology in the existing communication net-works. We explore in this paper, the possibility of exploiting QKD in the authen-tication process for local area networks (LANs). Precisely, we have elaborated a scheme to integrate the new technique of QKD in the CHAP protocol (Challenge Handshake Authentication Protocol) to enhance the security of the authentication service.
