Q1 Create a program that will initialise Port2 bits 0 - 7 to outputs. Then in an endless loop perform the sequence of bit manipulations shown below. Your program should use bit masking operations. Here is an outline of the program in pseudo-code and

This project presents FPGA implementations of the DES and Triple-DES with improved security against power analysis attacks. The proposed designs use Boolean masking, a previously introduced technique to protect smart card implementations from these

Abstract—This paper presents a highly effective compactor architecture for processing test responses with a high percentage of x-values. The key component is a hierarchical configurable masking register, which allows the compactor to dynamically ad
