Abstract
According to one or more embodiments of the present invention, a computer implemented method includes computing a hash value of a page of memory of a computer system and comparing the hash value with a previously computed hash value of the page. A per-encryption value per page can be used in encrypting the page based on determining that the hash value matches the previously computed hash value. A modified value of the per-encryption value per page can be used in encrypting the page based on determining that the hash value mismatches the previously computed hash value.
