Abstract
A method for execution by one or more processing modules of one or more computing devices of a dispersed storage network (DSN), the method begins by identifying, for data stored within a DSN memory, one or more encryption keys used to encrypt data stored within the DSN memory. The method continues by identifying, for data stored within a portion of the DSN memory requiring sanitization, a master key of the one or more encryption keys that encrypts all of the data stored within the portion to be sanitized. The method continues by determining, if the master key is not used to encrypt data stored outside of the portion to be sanitized. The method continues, if the master key is not used to encrypt data stored outside of the portion to be sanitized, by sanitizing the data stored within a portion of the DSN memory by erasing the master key.
