Possible NSA Decryption Capabilities
Introduction This document estimates the possible capabilities of the NSA in breaking certain types of cipher by exhaustive key search. It is a theoretical document, and only covers technical ability: in many cases the NSA will use alternative methods to break target cipher systems. The aim of this document is to give some estimates for the security of certain key lengths for some symmetrical (...
متن کاملOptimizing over the split closure
The polyhedron defined by all the split cuts obtainable directly (i.e. without iterated cut generation) from the LP-relaxation P of a mixed integer program (MIP) is termed the (elementary, or rank 1) split closure of P . This paper deals with the problem of optimizing over the split closure. This is accomplished by repeatedly solving the following separation problem: given a fractional point, s...

متن کاملCognitive Hacking
In this chapter, we define and propose countermeasures for a category of computer security exploits which we call "cognitive hacking." Cognitive hacking refers to a computer or information system attack that relies on changing human users' perceptions and corresponding behaviors in order to be successful. This is in contrast to denial of service (DOS) and other kinds of well-known attacks that ...

Believing it a remnant of the incomplete eradication of dogma in the empiricist tradition, Davidson wishes to undermine what he believes is the source of talk of conceptual relativism: the third dogma of scheme-content duality. Building on Quine, he constructs an argument intended to illustrate the peculiar p...
