In digital era A.L.U. methodologies are utilised to evaluate system performance. Due to the fact that the Arithmetic Logic Unit (ALU) is a necessary component of any Central Processing Unit, its significance is equivalent to that of the computer (CPU). Due to the rarity of devices lacking an ALU, ALU encryption is crucial for the security of the device. This article covers the design of an n-bit ALU using the HDL hardware description language to maximise the flexibility and reusability of the device. In addition, by utilising quantum dot cellular autumn, the maximum efficiency of the device and the logic of obfuscation used to enhance security without compromising operation are offered. Xilinx verifies and analyses the findings, indicating that the addition of the obfuscation module has no significant impact on the amount of space or power consumption of the ALU implemented in VERILOG HDL and synthesised by Xilinx.
