When you are developing security systems, new penetration techniques seem to appear as responses to new security measures but in general the flow is the other way around: security exists and evolves because of the evolution of threats. Beginning with the rise of radio in the 20th Century attacks on communication networks have shown two forms: those that go for the big kill—- such as the breaking of Enigma—- and those that assemble small seemingly innocuous leaks of information into a comprehensive understanding of the target’s behavior.

We will analyze the way in which these trends interact with others to create a situation in which what is possible in security and even the meaning of security in communication networks needs reexamination.
