Efficient Tiny Hardware Cipher under Verilog

Embedded hardware security has been an increasingly important need for many modern general and specific purposes electronic systems. Minute security algorithms with their expected low-cost and high-speed corresponding hardware realizations are of particular interest to fields such as mobile telecommunications, handheld computing devices, etc. In this paper, we analyze and evaluate the development of a cheap and relatively fast hardware implementation of the extended tiny encryption algorithm (XTEA). The development will start by modeling the system using finite state machines (FSMs) and will use Verilog hardware description language to describe the design. Minimizing the chip area will be our primary target rather than the construction of a multi-way massively parallel implementation with its expected high-speed and large silicon area. Many hardware design tools are used to try reaching the best possible optimized syntheses. The targeted hardware systems are the reconfigurable Altera’s Stratix II and Xilinx Virtex II Pro modern field programmable gate arrays (FPGAs).
