Network Security
monday, may 20, 14.15-18.00

With the advent of Internet, security breaches became a major concern for business applications and network operations. More recently security has also been viewed as a key issue in emerging networking research areas like ad hoc networks, mobile communications and multicast.

This tutorial will address the main communication security requirements and corresponding solutions from the perspective of Internet protocols and in some emerging networking fields. First a detailed overview of basic mechanisms including cryptographic techniques for data protection, authentication, key management, and network access control techniques used in firewalls will be presented.

IPsec protocols and key management schemes will then be introduced as an application of basic security mechanisms along with an overview of the Transport Layer Security protocol (SSL). In the last part of the tutorial, specific security requirements of multicast and related research work will be outlined.
