Low earth orbit satellite-based multicasting technologies are well-suited for secure group communications in a widely distributed, highly mobile environment. We present a novel modular multicasting architecture designed to increase system scalability for secure operations in a low earth orbiting satellite system. Simulation results demonstrate superior per-user average re-keying performance over baseline and clusterized architectures in various modeled scenarios. In scenarios with highly mobile users, the architecture achieved a nine-fold reduction in average user re-keying.
