Abstract

Data cryptography relies on safe commercial standards, such as the Advanced Encryption Standard (AES). These standards are deployed in the higher layers of the Open System for Interconnections reference model (OSI- RM). On the other hand, signal cryptography is implemented in the lowest layer of OSI-RM and is a current and promising research topic. Many proposals for the encryption of optical signals are pointed out in recent literature. However, to the best of our knowledge, the only one able to preserve both the bandwidth and the bit rate of the presently deployed wavelength division multiplexing (WDM) signals is the spectral phase and delay encoding (SPDE) scheme. SPDE also supports the propagation of encrypted signals through longer optical links than other techniques. Nevertheless, SPDE does not assure that the encrypted signals follow the diffusion and confusion properties, established by Shannon, and encompassed by an extensive myriad of data encryption standards. The main goals of this project are to develop and to test a new digital signal processing (DSP)-based strategy that grants SPDE with security features similar to those of data cryptography standards, such as AES. The electronically encrypted signal will further modulate am optical carrier. The performance of the resulting optical signal will be evaluated by means of simulations in VPITransmissionMaker® software. A partnership with CPqD Foundation may allow an experimental evaluation of these optical signals. This proposal is related to the participation of our group in the Photonics for Communications 2 (Fotonicom 2) Program of the National Institutes of Science and Technology, promoted by CNPq. (AU)
