Abstract
Polymorphic encryption is described to protect data in a vault. In one example, a method includes associating operations with at least a portion of the fields of a data set to form a plurality of operation field combinations, attaching an encryption scheme to each operation field combination, to enable the attached operation on values in the field when the values are encrypted without decrypting the values, associating a role with at least one operation field combination, encrypting the values in the at least a portion of the plurality of different fields in accordance with the attached encryption scheme, and providing access through the role to perform an operation that is associated with the role on a stored encrypted value in a field that is associated with an operation field combination that is associated with the role.
