- Abstract: Quantum key distribution (QKD) is the most used protocol in the context of
quantum cryptography for sharing a private encryption key between two parties.
Covid-19 pandemic has raised the ever-increasing need for online communications
a lot; this requires enhanced security protocols. QKD has the potential to meet
a global scale network's security requirements. Despite considerable progress,
all ground-based QKD approaches have distance limitations due to atmospheric or
fiber attenuation. A global network scheme can use intersatellite links to
establish a trusted node network with constellations. This enables key elements
for quantum internet which allows secure exchange of information between
quantum computers. The most cost-effective and iterative approach for this goal
is to exploit CubeSats. This paper summarizes technical challenges and possible
solutions to enable a global QKD network using CubeSats. We discuss practical
concerns and alternative paths involved with implementing such systems.

Byzantine agreement (BA) enables all honest nodes in a decentralized network to reach consensus.
We propose a quantum signed Byzantine agreement (QSBA) protocol based on the quantum signed message (QSM) scheme.
Our protocol achieves information-theoretic security using only QKD-shared key resources between network nodes.

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.
