XOR swap algorithm

In computer programming, the exclusive or swap (sometimes shortened to XOR swap) is an algorithm that uses the exclusive or bitwise operation to swap the values of two variables without using the temporary variable which is normally required. The algorithm is primarily a novelty and a way of demonstrating properties of the exclusive or operation. It is sometimes discussed as a program optimization, but there are almost no cases where swapping via exclusive or provides benefit over the standard, obvious technique. (Wikipedia).

Bitwise Operators 3: The XOR Operation

This computer science video describes the bitwise operation XOR. It explains how the XOR (eXclusive OR) operation works with unsigned integers and how the XOR operation can be used with a bitmask to manipulate the contents of a register containing bit flags. It also demonstrates how the

Table Of Ordered Pairs: Substitution | Algebra | Maths | FuseSchool

In this video we’re going to look at how to use substitution in equations to generate a table of ordered pairs. Ordered pairs (coordinates) can be used to solve equations, to plot graphs, and so we come across them a lot in Maths. You should already know how to substitute into equations,

27c3: News Key Recovery Attacks on RC4/WEP (en)

Speaker: Martin Vuagnoux In this paper, we present several weaknesses in the stream cipher RC4. First, we present a technique to automatically reveal linear correlations in the PRGA of RC4. With this method, 48 new exploitable correlations have been discovered. Then we bind these new b
