- 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.
