Secret Key Agreement by Soft-decision of Signals in Gaussian Maurer's Model

, 2008
We consider the problem of secret key agreement in Gaussian Maurer's Model. In Gaussian Maurer's model, legitimate receivers, Alice and Bob, and a wire-tapper, Eve, receive signals randomly generated by a satellite through three independent memoryless ...

A New Key-Agreement-Protocol

, 2009
A new 4-pass Key-Agreement Protocol is presented. The security of the protocol mainly relies on the existence of a (polynomial-computable) One-Way-Function and the supposed computational hardness of solving a specific system of equations.Comment: 4 ...

Conference Key Agreement and Quantum Sharing of Classical Secrets with Noisy GHZ States

, 2004
We propose a wide class of distillation schemes for multi-partite entangled states that are CSS-states. Our proposal provides not only superior efficiency, but also new insights on the connection between CSS-states and bipartite graph states.

An Improved GN-AK Protocol Using Double-Base Scalar Multiplication and Point Halving over Elliptic Curves

Applied Sciences
Starting from the basic form of GN-authenticated key agreement (GN-AK), the current research proposes an improved protocol by integrating a new scalar multiplication technique based on a dual-base chain representation with bases 1/2 and 3.

Multipartite Quantum Key Agreement Over Collective Noise Channels

IEEE Photonics Journal, 2018
In this paper, two classes of multiparticle entangled states are constructed to resist against the collective-dephasing noise and collective-rotation noise, respectively.
