The embodiments relate to a data storage device for protected data exchange between different security zones including at least a storage unit, a data validation unit, and an access control unit. The storage unit has a first interface to a first security zone, via which the data elements may only be written to the storage unit. The storage unit also has a second interface to a second security zone, via which data elements may only be read from the storage unit. The validation unit is equipped to check the data elements written to the storage unit for agreement with a predetermined pattern. The access control unit is set up to permit the data elements to be read from the storage unit only when the data elements are found to be in agreement and are thus applicably validated. |
