1. A method for allocating at least one encryption parameter to at least one user for encryption of data to be stored in an information processing system, the method comprising:

  • requesting the at least one encryption parameter by a data processing system which encrypts the data to be stored, wherein the data to be stored is generated by the at least one user using the data processing system;

    determining, by a key server device, the at least one encryption parameter in response to the request;

    the at least one encryption parameter being a symmetric encryption parameter;

    transmitting the at least one encryption parameter to the data processing system;

    generating, by a database server device, an allocation information configured to associate the at least one encryption parameter with an identifier of the data processing system;

    associating the identifier with the data to be stored or the user; and

    storing, by at least one of a backup key server device and a policy server device, the allocation information so as to be accessible to at least one authorized third party.
