By connecting computers
together, very large and surprisingly reliable systems can be built. At the
fundation of all these endeavors is networking. The course is about properties
and technologies for connecting computers together. As the systems are applied
in ever more important environments, properties related to authenticity and
possibly privacy becomes paramount. The latter implies cryptography.
The course focuses on
properties of communication between computers, and the machinery needed to
faciliate the communication. Among the properties are those arising from the
uncertainty of delivery, the omnipresence of errors, and lack of global
consistence and authority. There are many technical solutions; their design and
implementation is discussed. As computers are used to manipulate real world
valuables ever more demands are placed on Authentication, Authorization, and
Auditing. Across a network, only cryptographic technology can assist in
upholding interesting properties. Both symmetric- and asymmetric encryption
will be presented and discussed.
