ABSTRACT:
This invention report describes the architecture of a system, which undertakes in a new way the dynamic generation of symmetrical keys and the confidential synchronization of encryption components which use these keys. The basis is formed by the principle of the one-time-pad, with which absolute confidentiality can be ensured in theory. The difficulties with practical implementation of a pure one-time-pad can be avoided by expansions.
