Upgrading PPP security by Quantum Key Distribution
نویسندگان
چکیده
Quantum cryptography could be integrated in various existing concepts and protocols to secure communications that require very high level of security. The aim of this paper is to analyse the use of quantum cryptography within PPP. We introduce basic concepts of the Point to Point Protocol; we propose a solution that integrates quantum key distribution into PPP. An example is given to demonstrate the operational feasibility of this solution

Enhancing Grid Security using Quantum Key Distribution
Quantum Key Distribution (QKD) is a secure key distribution technology, which provides information theoretic or unconditional security. 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...
متن کاملImproving Tls Security by Quantum Cryptography
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 p...

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 protocol...
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...
متن کاملSecurity of Quantum Key Distribution
We construct a new quantum key distribution scheme and prove its security against the most general type of attacks and the most general type of noises allowed by quantum physics. The novel technique we use is reduction from a quantum scheme to a classical scheme. We first show that, rather surprisingly, the proof of security of our quantum key distribution in the error-free case can be reduced ...
