2.3 AUTHENTICATION/INTEGRITY OVERVIEW
2.3,1 GENERAL
Undetected data modification or corruption is a major concern. It could affect the integrity (correctness) of data received either on the ground from the spacecraft or on the spacecraft from the ground (i.e., what was received is exactly what was transmitted or any unauthorized modifications are detected and flagged). Modified or corrupted commands transmitted to the spacecraft could result in catastrophic results such as total mission loss. Modified or corrupted payload data from the spacecraft could result in erratic or wrong science. Modified or corrupted telemetry (e.g.. housekeeping or engineering data) might be acted, upon resulting in a catastrophic event (e.g., telemetry indicates incorrect high onboard temperatures resulting in controller actions that could harm the spacecraft). The spacecraft/instrument must have the ability to recognize and discard unauthorized commands.
