Abstract
A system for protecting data includes a virtual zeroisation device which receives data to be encrypted and key material for encrypting the data. The key material is stored in a storage device. As the encryption unit encrypts the data using the key material, the encrypted data is stored in the storage device and overwrites the key material.
