摘要：
An all-optical cryptographic device for security applications, based on the properties of soliton beams, is presented. It is able to codify a given bit stream of optical pulses, changing their phase and their amplitude as a function of one or more encryption serial keys that merge with the data stream, generating an incomprehensible stream. Its great advance is represented by its capability of encrypting in real time, without slowing the data flow that can be transmitted with its original velocity.
