Abstract
A selectively encrypted data unit is generated from an unencrypted data unit. This is accomplished by accessing a list of attributes related to the unencrypted data unit that identify classifications of sensitive information within the unencrypted data unit. In addition, a protection key that is responsive to a random number is selected and auxiliary values computed from the attributes of the sensitive information and the random number are produced. The sensitive information is encrypted with the protection key to create an encrypted version of the sensitive information. The encrypted version is associated with the auxiliary values and linked to an attribute vector that classifies the sensitive information in the encrypted version. Data from the unencrypted data unit and the encrypted version of the sensitive information is stored as the selectively encrypted data unit.
