• Abstract: Conference key agreement (CKA), or multipartite key distribution, is a cryptographic task where more than two parties wish to establish a common secret key. A composition of bipartite quantum key distribution protocols can accomplish this task. However, the existence of multipartite quantum correlations allows for new and potentially more efficient protocols, to be applied in future quantum networks. Here, we review the existing quantum CKA protocols based on multipartite entanglement, both in the device-dependent and the device-independent scenario.

  There are two primary approaches to achieving quantum-resistant security: quantum key distribution (QKD) and post-quantum cryptography (PQC) We introduce the pros and cons of these protocols and explore how they can be combined to achieve a higher level of security and/or improved performance in key distribution. We hope our discussion inspires further research into the design of hybrid cryptographic protocols for quantum-classical communication networks.

  Quantum networks connect and supply a large number of nodes with multi-party quantum resources for secure communication, networked quantum computing and distributed sensing. As these networks grow in size, certification tools will be required to answer questions regarding their properties. We demonstrate a general method to guarantee that certain correlations cannot be generated in a given quantum network.

  Twin-Field Quantum Key Distribution (TF-QKD) enables two distant parties to establish a shared secret key. TF-QKD is the only scheme capable of beating the repeaterless bound on the bipartite private capacity. We propose a practical conference key agreement protocol that only uses WCPs and linear optics and prove its security with a multiparty decoy-state method.

  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-Zeilinger (GHZ) state to distil a secure N-user conference key bit.

  Conference key agreement (CKA) is an extension of key distribution to multiple parties. CKA can also be performed in a way that protects the identities of the participating parties, therefore providing anonymity. We propose an anonymous CKA protocol for three parties that is implemented in a highly practical network setting.
