Adaptive encryption protocols

Some new ideas are presented for the improvement of the known QKD protocols and their application to an Internet environment. The full automatization of a technological setup is considered, as a result of the property of most basic QKD protocols to have the appearance of step by step algorithmic procedures and thus to offer themselves to materialization as computer code applications. This is the basis for the creation of a computer network connecting various users to be developed, working as an expert system and making decisions on the best strategy to recognize and counter especially dangerous eavesdropper attacks. The use of robotic technology, knowledge based simulation of the most dangerous and complicated attacks, game theory and neuronal networks to make these decisions, permits the system to adapt its behavior in the face of adverse situations. An elementary example of adaptivity of QKD protocols, by the use of game theory, is given.
