UniForum Chicago is proud to announce the topic for the October 9, 2012 SIG meeting: "Steganography Over The Covert Channels Of TCP/IP" by Hal Wigoda.
Our meetings are free and open to the public and begin promptly at 7pm at the IIT Rice Campus in Wheaton, IL. Additional information regarding this presentation can be found at http://www.uniforumchicago.org (http://www.uniforumchicago.org/)
Hope to see you there!
Steganography is about concealing the very existence of a message itself. Like cryptography, steganography is secretive. Data can be hidden in web pages and/or the embedded images that pass over the Internet, a relatively easy task to perform and perhaps just as easy to examine. An even more surreptitious and unique way to hide messages would be in the unused fields of the packet headers of the TCP/IP protocol suite. Such methods involve utilization of a covert channel. A covert channel is a communication channel that allows two cooperating processes to transfer information in a manner that violates the system's security policy. The packets used for carrying the message can appear innocuous and beyond suspicion. But data can be hidden in other data, a picture, an audio or video file, or even in the network packet as it moves across the wire. This is the covert channel of the Internet TCP/IP.
Once we have finished, we will adjourn to nearby Cozymel's Mexican restaurant for food and drinks.
