Higher performance secure outer space communications at lower cost utilizing commercial components

In space environments, electronic devices suffer from radiation effects, producing bit flips and upsets. Even a single upset can disrupt the operation and the fidelity of data. Many of the problems encountered in space operations of electronics are overcome by radiation hardening. We present a software based approach as an alternative to the previously common reliance on hardware for radiation hardening. There are clear advantages in using easily available, "off the shelf" electronic components instead of esoteric specialized components. The work presents analysis and methods which highlight technological, logistical and financial advantages of utilizing commercial components. We present a comparative analysis and identify Graphics Processing Units as a viable and attractive route for encrypted data communications with satellites.
