Computing networks have fundamentally changed the ways in which we use computers. The ubiquity of networks and their broad range of uses have created substantial challenges in the area of computer communication. Not only must data be delivered quickly and reliably from one computer to another, but in many cases that data must also be secure from eavesdroppers. Moreover, the recipient of the information often needs to be sure of the identity of the sender. Encryption can be used to achieve both security and authentication of information. This course will begin with the problem of communicating between two computers, followed by the problem of building generalized networks for an arbitrary number of computers. Networking topics will include layered network structure, signaling methods, error detection and correction, flow control, routing, and protocol design and verification. We will then examine in detail a variety of encryption schemes, how they can be used, and how secure they are. Cryptographic topics will include classical cryptosystems, the data encryption standard, public-key cryptography, key escrow systems, and public policy on encryption. Offered in alternate years.
