CRYPTOGRAPHY AND CYBERSECURITY
92359

Description
Objectives
Description of the basic principles of modern cryptography, with reference to both symmetric and asymmetric methods, as well as to the main known cryptanalytic attacks. Description of the problems and solution approaches involved with cryptographic key management and distribution. Again, the problem will be analyzed considering both symmetric and asymmetric cryptographic schemes. Description of the problem of data integrity, authentication, and digital signatures, applied to data transmissions. Description of the emerging topic of physical-layer security of wireless communications.
