SUMMARY:

The course introduces a refreshment summary on discrete mathematics, number theory and the basic contemporary cryptographic algorithms. The review concentrates on modern network security relevant symmetric and asymmetric cryptography including Digital signatures, certificates and authentication protocols. Contemporary network security technology related standards as (X.509, DSS, Kerberos), electronic mail security (PGP, S/MIME) as well as (IPSec, SSL, TLS, SET and others) would be presented showing their design concepts. Web security and protocols for secure electronic commerce, voting systems and other contemporary applications would cover the final concluding part of the lecture. The course concludes with modern trends in network security applications for voting, vehicular, sensor and similar networks.

Perquisites: Knowledge on Basic Communication Networks and Cryptography
