Abstract

This paper presents the design and implementation of a digital integrated encryption/decryption circuitry called LAM which is based on Peripheral Component Interconnect (PCI) Architecture for a Personal Computer (PC) communication card. The implementation of a hardware PC cryptography card has been designed using a Field Programmable Gate Array (FPGA) chip in combination with the PCI Bus. The main objective of this paper is to provide the reader with a deep insight of the design of a digital cryptographic circuit, which was designed for a FPGA chip with the use of Very (High-Speed Integrated Circuit) Hardware Description Language (VHDL) for a PCI card. A demonstration of the LAM circuitry will be presented. To see the effect of the LAM cryptography in the operation of the card, it was also simulated and analyzed. The Simulations were run under various conditions, which are applicable to most PCI applications.
