I. Define the concept of an exclusive OR operation (OR) and its importance to cryptography.
II. Comprehend that bit stream methods commonly use algorithm functions like the exclusive OR operation (XOR), whereas block methods can use substitution, transposition, XOR, or some combination of these operations.
III. Identify that XOR is a function of Boolean algebra, and if two bits are identical when compared, the binary result is 0, and when they are not, it is 1. Apply Table 10-3 as part of the discussion.
