One of the most important elements in cryptography is the bit, the foundation of digital information. Working with bits requires different logical operations, such as OR, AND, or XOR. MATLAB implements these operators automatically, as well as some types of conversions to bits, as you will see in this chapter. Other important aspects of cryptography are arrays or matrices. These have many applications. For example, the elements of a finite group are stored in an array, ...
