T5   Secure Communications Over Open Networks  New
Marcus J. Ranum, Network Flight Recorder, Inc.

Who should attend: Programmers, network managers, and individuals who need to develop or deploy secure communication systems. You should have some experience with TCP/IP and UNIX.

Individuals increasingly rely on electronic communications as a daily part of their private lives. Corporations rely on Internet services as essential tools for their business. At the same time, many of the tools lack the most basic protections against snooping and tampering. To make matters more interesting, governments are becoming concerned that civilian use of secure communications may threaten national security and they are pushing for various degrees of regulation.

If you are an experienced network and system manager, you will learn how to build and deploy a wide range of secure communication tools. Tools will be discussed within the overall context of communication security and appropriateness. Topics will range from the highly paranoid (including basic spycraft and covert channels) to the practical (such as building your own VPN router or operating PGP). We will cover actual configurations, set-up procedures, and command lines for software packages on BSD UNIX. Debugging and verifying operation will also be discussed.

Topics will include:

-    The communications security environment
-    Covert operations: introductory spycraft
-    Absolute security: one-time-pads
-    DES encryption
-    Email security: PGP
-    Hiding communications: steganography
-    Virtual private networks: using SSH and IPSEC
-    Privacy: anonymous remailers, anonymizers, and crowds
-    Up and coming technologies
-    The regulatory environment
-    Where to get crypto-munitions
