Abstract
An apparatus receives a signal to perform secure erasure of a storage medium. The apparatus, responsive to reception of the signal, erases the storage medium by performing at least the following operations. An encryption key is erased. The encryption key is stored on the storage medium and is used to encrypt data on the storage medium. The apparatus generates a fake encryption key that is different from the encryption key and stores storing the fake encryption key on the storage medium. The encryption key and/or fake encryption key may be stored on the medium in multiple parts. The encryption key may be generated using random data from the medium. The apparatus may be the storage medium or a computer system that access the storage medium. The erasure can be performed in response to a request by a user. The medium may be an erasure-resistant storage medium.
