VULNERABILITY OF “A NOVEL PROTOCOL-AUTHENTICATION ALGORITHM RULING OUT A MAN-IN-THE-MIDDLE ATTACK IN QUANTUM CRYPTOGRAPHY” AYSAJAN ABIDIN and JAN-ÅKE LARSSON

چکیده
In this paper we review and comment on “A novel protocol-authentication algorithm ruling out a man-in-the-middle attack in quantum cryptography”, [M. Peev et al., Int. J. Quant. Inform., 3, 225, (2005)]. In particular, we point out that the proposed primitive is not secure when used in a generic protocol, and needs additional authenticating properties of the surrounding quantum-cryptographic protocol .

RULING OUT A MAN-IN-THE-MIDDLE ATTACK IN QUANTUM CRYPTOGRAPHY” AYSAJAN ABIDIN and JAN-ÅKE LARSSON
Quantum Cryptography, or more accurately Quantum Key Distribution (QKD), is an unconditionally secure key growing technique based on the principles of quantum mechanics. It is unconditionally secure because no quantum state can be copied or measured without disturbing it. However, the practical implementation of QKD protocols requires an immutable public channel. In case the public channel is n...
متن کاملWeaknesses of Authentication in Quantum Cryptography and Strongly Universal Hash Functions
Authentication is an indispensable part of Quantum Cryptography, which is an unconditionally secure key distribution technique based on the laws of nature. Without proper authentication, Quantum Cryptography is vulnerable to “man-in-the-middle” attacks. Therefore, to guarantee unconditional security of any Quantum Cryptographic protocols, the authentication used must also be unconditionally sec...
متن کاملA TESLA-based mutual authentication protocol for GSM networks
The widespread use of wireless cellular networks has made security an ever increasing concern. GSM is the most popular wireless cellular standard, but security is an issue. The most critical weakness in the GSM protocol is the use of one-way entity authentication, i.e., only the mobile station is authenticated by the network. This creates many security problems including vulnerability against m...
متن کاملAttacks on quantum key distribution protocols that employ non-ITS authentication
We demonstrate how adversaries with large computing resources can break Quantum Key Distribution (QKD) protocols which employ a particular message authentication code suggested previously. This authentication code, featuring low key consumption, is not Information-Theoretically Secure (ITS) since for each message the eavesdropper has intercepted she is able to send a different message from a se...
متن کاملAuthentication in Quantum Key Distribution : Security Proof and Universal Hash Functions
Quantum Key Distribution (QKD) is a secret key agreement technique that consists of two parts: quantum transmission and measurement on a quantum channel, and classical post-processing on a public communication channel. It enjoys provable unconditional security provided that the public communication channel is immutable. Otherwise, QKD is vulnerable to a man-in-the-middle attack. Immutable publi...
