  Quantum key distribution (QKD) via satellite links is the only currently
viable solution to create quantum-backed secure communication at a global
scale. To achieve intercontinental coverage with available technology one must
adopt a "flying trusted node" paradigm, in which users fully trust the
satellite platform. Here, inspired by the concept of distributed secret sharing
and the imminent projected launch of several QKD-equipped satellites, we
propose a parallel trusted node approach, in which key distribution is mediated
by several satellites in parallel. This has the effect of distributing the
trust, removing single points of failure and reducing the necessary
assumptions. In addition, we discuss the versatility that an optical ground
station should provide to execute such a protocol and, in general, to be fully
integrated into a multi-party global quantum network.
