Abstract: A cryptation system for information transmitted through packet switching networks including masking the digital information data by combining them at the transmitting station with digital data of a certain code of cryptation before transmitting the so encrypted data through the network and performing an inverse decrypting processing at the receiving station using the same code of encrypting, comprises generating at a transmitting station and at a receiving station, starting from a given pair of password codes or user key, a certain discrete chaotic model or map of said pair of codes or key, producing dynamically updated pairs of values of codes or keys every certain number of processing steps of said chaotic map, masking the data to be transmitted by way of a logic combination with said current dynamically updated keys at the transmitting station, demasking the data at the receiving station by way of a logic decomposition of said digital data from said current dynamically updated key returning the digital data to a clear condition.
