Design and implementation of a universal communication security unit on an FPGA

The paper presents an integration of both encryption and authentication algorithms in one chip. The proposed unit is designed using Mentor Graphics FPGA Adv. Pro tools and implemented on XILINX XC4085XL chip. The encryption system used is based on the synchronous stream cipher algorithm. Both functional and timing simulation are performed. The output of the unit passed the randomness tests performed namely frequency, serial and poker tests.
