Corso di L. Specialistica in Ingegneria Delle Telecomunicazioni (Communication Engineering)  Torino 





Obiettivi dell'insegnamento
This course is an introduction to cryptography, the science of secret writing, or in modern terms, the science of communication protection against malicious alterations. The basic intention is to present fundamental concepts, mathematical methods, and characteristic techniques of cryptography. Then, scope of the course is to provide the background necessary for dealing with methods and tools which are indispensable in the broad field of information protection.
The lectures are mainly theoretical, although the abstract speculations have direct practical applications. 
Programma
Cryptography is the science that studies the methods for protecting any kind of data in communication systems, storage systems, and information manipulation systems.
A brief historical excursus from the ancient to modern times culminates with the Shannon model of a cryptographic channel, which is thus analyzed in the framework of information theory. The fundamental notions of privacy, integrity, and authentication that constitute the central targets of modern cryptography are defined and illustrated. Thus, the basic concepts of secretkey and publickey are introduced, motivated, and described along with the indispensable mathematical methods drawn from algebra and number theory.
