Abstract: The present invention concerns interprocess communication systems consisting of an arbitrary number of homogeneous or heterogeneous physically connected units, where a central unit executes at least one central process—called Central Process—and at least one of the units executes peripheral process(es), which are connected to the Central Process via at least one standing logical bidirectional connection. The Central Process assigns logical identifications to the connections of the peripheral processes. Using these logical identifications, peripheral processes can communicate independently of the physical units with selected peripheral processes or connections. Peripheral processes of the same kind can be exchanged transparently for other peripheral processes. Peripheral processes can maintain parallel connections to multiple Central Processes and Central Processes can be linked directly or indirectly via links to arbitrary hierachies or topologies.

Abstract: The present invention—called Efficient Description Language EDL—concerns methods to describe, parsers and generators of as well as systems storing, processing, transmitting or using arbitrary hierarchical data structures in a platform independent format and overcomes the prior art limitations using only a single starting respectively terminating character to introduce respectively terminate individual branches and data elements.

Abstract: The presented inventions concern communication systems with services. The services provided by the presented systems are invisible to port scans, allowing security critical data to be stored on units without any permanently open connection endpoints. Existing network systems according to the client/server-principle require the permanent provision of open connection endpoints to be accessible on a 24h base. The large number of services implies a large number of open connection endpoints, where each open connection endpoint presents a potential point-of-attack for malicious clients. The object of the present invention is to securely provide services in communication systems. The present invention overcomes the prior art by triggerable invisible services, which during normal operation do not provide any permanently open connection endpoint. Connection endpoints are only opened after prior client authentication and authorization validated by an independent logon sub-system.

Abstract: The present invention concerns symmetric and asymmetric encryption key management methods and sets of encryption methods to encrypt and decrypt arbitrary data, which can be divided into n (n>=2) data blocks D0, . . . , Dn−1, continuous data streams of known or unknown length or sequences of a known or unknown number of messages between at least two communication partners using variable—in particular arbitrarily selectable and/or randomized one-time—encryption keys.

Abstract: Existing network systems based upon the client/server principle require on the server side the provision of open connection endpoints. The large number of server processes implies a large number of open connection endpoints. Each open connection endpoint is also a potential target for an ill-minded attacker. The present invention minimizes the risk of a break-in into a network with security critical data.
