Watchdog key system for data security in unmanned undersea vehicles

Abstract:

An underwater vehicle system includes a data security system. The data security system includes a data pod including persistent storage. The persistent storage stores encrypted data. The security system includes a watchdog. The watchdog includes at least one processor. The security system includes a watchdog key. The watchdog key is stored in volatile storage. The watchdog key is configured to be used to decrypt the encrypted data. The data security system is configured to remove the watchdog key from the underwater vehicle system, thereby preventing access to the encrypted data on the data pod.
