Abstract
The present invention relates to a method for encryption of the content in a database, for accomplishing increased protection against unauthorised access to the data. The method assures that every row and item is re-encrypted with a valid key. More specifically this process, the so-called KeyLife process, is executed every time a row is inserted, updated or retrieved after a scanning operation. The key life value, defining the number of days a key is valid for each item, could differ for the items, and could typically be between 30 and 90 days. The scanning operation, checking the validity of the presently used keys, the so-called KeyLife checking, is executed each time a new key generation is created.
