Abstract: Almost every month, there are new reports of hackers who were able to acquire millions of data items and passwords. The problem: even if data are sufficiently encrypted, there must be a key somewhere for decryption. If this key can be stolen, the best encryption is of no use. Instead of conventional keys, the present overall data protection concept uses future events as a secret basis for encryption. Data are coded repeatedly with variable and partly only transient keys which are not permanently stored but are coded with time codes which result from unpredictable future timer events and are therefore impossible to steal. Various measures protect keys against viewing even during the immediate use thereof, and an optional hardware expansion excludes any possibilities of manipulation, with the result that there is no longer any risk even in captured systems.
