A cryptographic system consists of a one to one enciphering transformation f from a set \(\mathcal{P}\) of plaintext message units to a set \(\mathcal{C}\) of ciphertext message units. For example, for a fixed N- letter alphabet, identified with ℤ/Nℤ, consider the mapping f : \(\mathcal{P}\) = ℤ/Nℤ → 𝑪 = ℤ/Nℤ given by f(P) = \(\mathcal{C}\) ≡ aP + b ...

In this short chapter, we talk a bit about cryptography. First, we discuss some classical sorts of private key methods, and their limitations in the modern world. We then look at the first public key cryptographic method.

Today’s widespread use of electronic networks in the economic world has raised cryptography from a speciality of the military and secret services to a topic of public interest, which concerns international organisations like the UNO ([UNCITRAL, 1998a] and [UNCITRAL, 1998b]) and the EU ([Commission of the European Communities, 1998]).

The problem of key distribution has been mentioned many times in this book. For many years it was strongly believed that this problem has no satisfactory solution, but in the 1970s, an ideal, simple solution was found and has since become the foundation upon which much of modern cryptography is based.

A tutorial on public key cryptography
Computers & Security, 1982Abstract Public key cryptography provides the means for establishing instantaneous, secure communication between any two persons or any two computers. The prior exchange of a secret quantity, called the cryptographic key, is not necessary. In this paper, the underlying mathematical principles of public key (PK) cryptography are informally introduced ...
