Unique Information and Secret Key Agreement [PDF]
Entropy, 2018 The partial information decomposition (PID) is a promising framework for decomposing a joint random variable into the amount of influence each source variable X i has on a target variable Y, relative to the other sources.

Conference key agreement in a quantum network [PDF]
npj Quantum Information, 2023 Quantum conference key agreement (QCKA) allows multiple users to establish a secure key from a shared multi-partite entangled state. In a quantum network, this protocol can be efficiently implemented using a single copy of a N-qubit Greenberger-Horne ...

A SECURE KEY AGREEMENT PROTOCOL [PDF]
Journal of Information and Organizational Sciences, 2001 In this paper we propose a secure protocol for an authenticated key agreement based on the Diffie-Hellman key agreement, which works in an elliptic curve group We prove that our protocol meets the security attributes under the assumption that the ...
