Actions of Authentication Unit Shell

The Authentication Unit Shell is a software component. It contains the complexity of the authentication process and presents only simple interfaces. This makes it easy to integrate into any system that requires authentication facilities, such as:

telecommand encoder of a Spacecraft Control System
telecommand encoder of a Spacecraft Ground Testing System (EGSE)
telecommand decoder of a Spacecraft Simulator

We also provide support for the Authentication Unit as an option for our Telecommand Encoder Shell and Telecommand Decoder Shell packages.

Please contact us for further information on technical questions or licensing conditions for our Authentication Unit software packages.
