Security of EPR-based Quantum Key Distribution
We propose a proof of the security of EPR-based quantum key distribution against enemies with unlimited computational power. The proof holds for a protocol using interactive error-reconciliation scheme. We assume in this paper that the legitimate parties receive a given number of single photon signals and that their measurement devices are perfect.
متن کاملSecurity of EPR-based Quantum Key Distribution using three bases
• m, the length (in bits) of the private key to be generated. • ǫ, the maximum threshold value for the error rate during the quantum transmission (ǫ < 1/4). • τ , a security constant such that ǫ 1−ǫ < ǫ 1−ǫ + τ < 1. • the security parameter r. It must be large enough so that Alice and Bob can find a binary matrix K of size m × r such that any linear combination of rows of K that contains at lea...
متن کاملEntropy Security in Quantum Cryptography
Quantum mechanics is the basic principle which is applied in the cryptographic scenario of quantum cryptography. Present paper provides a conceptual framework on the high level security protocol in Quantum cryptography. This is used as a base for data security through quantum computing in modern cryptosystem. In this paper first of all a detailed description of BB84 protocol with noise and with...
متن کاملEntropic security in quantum cryptography
We present two new definitions of security for quantum ciphers which are inspired by the definition of entropic security and entropic indistinguishability defined by Dodis and Smith. We prove the equivalence of these two new definitions. We also propose a generalization of a cipher described by Dodis and Smith and show that it can actually encrypt n qubits using less than n bits of key under re...
متن کاملNetwork Security Using Quantum Cryptography
Network security and cryptography is a subject about how to protect information in digital form and to provide security services. The purpose of a digital signature is to provide a means for an entity to bind its identity to a piece of information. The common attacks on digital signature were reviewed. The first method was the RSA signature scheme, which remains today one of the most practical ...
