Combinatorial Cryptography and Latin Squares

In this chapter, we first overview the applications of combinatorics in cryptography. Then, we take look at some historical applications of non-combinatorial squares and cubes in cryptography. After these preliminary discussions, we study the applications of combinatorial squares and cubes in cryptography with a focus on Latin/magic squares and cubes. Among these constructs, Latin squares will be used to represent perfectly secure encryption-decryption algorithms in the last chapter of this part.
