Abstract: This paper presentsa modified Extended Tiny Encryption Algorithm (XTEA). A nonlinear Boolean function called Nmix is used to replace addition modulo 232 .Proposed design has been implemented on a FPGA platform. Simulation result shows that it requires a reasonable hardware and provides an acceptable throughput. It is shown that proposed design requires less hardware compared to XTEA.
Keywords: Extended Tiny Encryption Algorithm (XTEA), Nonlinear Mixing Function, VLSI Implementation.
