What happens to keys stored in the EPLRS if the power source fails?

When the power source of the Enhanced Position Location Reporting System (EPLRS) fails, the keys stored in the system are lost. This is because the keys are often kept in volatile memory, which requires a constant power supply to maintain their integrity. When the power is cut off, the data held in this type of memory is erased or becomes inaccessible.

Options related to the keys remaining intact, being automatically restored, or being sent to backup do not accurately reflect the nature of data stored in a volatile memory system such as that used in EPLRS. Without an uninterrupted power supply, the data cannot be preserved, thereby resulting in the loss of the keys. Understanding this characteristic of volatile memory is crucial for managing data security and system integrity in military communication systems like EPLRS.
