Abstract
It is the object of the invention to realize a low-cost, low-effort cryptoanalytically secure encrypting/decrypting method for high data rates and large code key spaces. The solution provides for a message encrypting/decrypting system whereby the keys are contained in a memory in the form of a branching network with cross-linked nodes and branches. For encrypted/decrypted data transmission by process participants, it is possible to realize the cryptological functions "authorization", "identification", "authentication", "electronic signature", "one time key", among others. The solution is especially usable in the application fields "electronic access and data securing", "telecommunication services", and "electronic bank and payment services", for example, for the cash money substitution.
