Abstract
Polymorphic encryption is described in a way to restrict access and enhance security of a data vault. In an example, the data vault has a primary partition with a first subset of records having an encrypted value for each of at least a portion of the fields encrypted according to a first encryption scheme. A secondary partition has a second subset of the records encrypted according to a second encryption scheme that is different from the first encryption scheme. The first encryption scheme is configured to permit a first set of operations on the values when the values are encrypted and the second encryption scheme is configured to permit a second set of operations on the values when the values are encrypted.
