Six-state protocol was introduced by Pasquinucci and Gisin in 1999 in their article "Incoherent and coherent eavesdropping in the six-state protocol of quantum cryptography.". [21]). BB84-PROTOCOL IMPLEMENTATION Maurer's "Universal Normal minimum of 387,840 bits AND SIMULATIOM Statistical" Test To examine the relation between the randomness and the NIST QKD, The BB84 is simulated using a Core i3 (2.4 GHz) processor associated with 4GB of RAM. The Rectilinear states are represented by the " +" symbol and The protocol is provably secure, relying on the quantum property that information gain is only possible at the expense of disturbing the signal if the two states we are trying to distinguish are not orthogonal (see no cloning theorem). Another variant of BB84 is the Six-State Protocol (SSP) proposed by Pasquinucci and Gisin in 1999 . BB84 and Ekert91 protocols. Quantum Key Distribution Protocols and Applications Sheila Cobourne Technical Report RHUL{MA{2011{05 8th March 2011 Department of Mathematics Royal Holloway, University of London In this chapter, I define the BB84 protocol, although I already described it informally in Section 1.1. In this paper, BB84 protocol is used to implement QKD, that deals with the photon polarization states used to transmit the telecommunication information with high level of security using optical fiber. As we said, in real BB84 implementation, they can do it over a public channel - in our case we just do it in process. The performance of a QKD implementation is determined by the tightness of the underlying security analysis. The implementation of BB84 protocol using QKD is . 3.5 Quantum Fourier Transform. In a typical optical implementation of this scheme, the sender uses an active source to produce the required BB84 signal states. There are, of course, more advanced versions of QKD protocols, like the SARG protocol [25], but we will not BB84 is a quantum key distribution scheme developed by Charles Bennett and Gilles Brassard in 1984. The BB84 Protocol was proposed by Bennett and Brassard in 1984. shown in Fig.3. The BB84 protocol implementation as five objects, which are Alice, Bob, Eve, Quantum Channel, Public Channel. In such case, they would abort the protocol and retry again. different polarisations of a photon) transmitted through a quantum channel to carry Alice's random key. The six-state protocol was introduced by Pasquinucci and Nicolas Gisin in 1999 in their article "Incoherent and coherent eavesdropping in the six-state protocol of quantum cryptography.". 59-67 60. is based in its design on Heisenberg's Uncertainty .
