A Robustness-Agile Encryptor (RAE) provides confidentiality services for each Asynchronous Transfer Mode (ATM) virtual circuit at an arbitrary strength (or cryptographic robustness). This enhances ATM’s flexibility, particularly in cases where political or policy constraints limit the choices for encryption algorithms. It may also reduce operational costs,(More)
With the build-out of large transport networks utilizing optical technologies, more and more capacity is being made available. Innovations in Dense Wave Division Multiplexing (DWDM) and the elimination of optical-electrical-optical conversions have brought on advances in communication speeds as we move into 10 Gigabit Ethernet and above. Of course, there is(More)
This document describes the design, fabrication, and testing of the SNL Data Encryption Standard (DES) ASIC. This device was fabricated in Sandia's Microelectronics Development Laboratory using 0.6 μm CMOS technology. The SNL DES ASIC was modeled using VHDL, then simulated, and synthesized using Synopsys, Inc. software and finally IC layout was performed(More)
