Any message written over a fixed set of symbols can be represented as a binary string (a sequence of 0s and 1s)Binary digits 0 and 1 are called bitsTo reduce computation overhead, encryption algorithms should only use operations that are easy to implementFor a binary string X:The length of X, denoted by |X|, is the number of bits in XIf |X| = l, X is an l-bit binary stringLet a be a binary bit and k a non-negative integer. Denote by ak a binary string consisting of k copies of aDenote the concatenation of X and Y by XY or...
