1. A method for execution by a computing device of a dispersed storage network (DSN), the method comprises: encrypting a data segment of a data object using a security key to produce an encrypted data segment; dispersed storage error encoding the encrypted data segment to produce a set of encoded data slices; sending the set of encoded data slices to storage units of the DSN for storage therein; encrypting the security key using an encryption key to produce an encrypted security key; dispersed storage error encoding the encrypted security key to produce a set of encoded key slices, wherein a decode threshold number of encoded key slices is needed to recover the encrypted security key; and sending the set of encoded key slices to a set of storage units of the DSN for storage therein.
