There is a very clever and beautiful algorithm that only uses the xor operation. It's the Luby Transform code, the simplest implementation of a Fountain Code. A Fountain Code lets you transmit a file over an unreliable connection (packets can be unordered, and even lost), with just a unidirectional communication. And this can be done just by xoring a random number of blocks from the file over and over! A very good explanation of the algorithm: http://blog.notdot.net/2012/01/Damn-Cool-Algorithms-Fountain-Codes http://blog.notdot.net/2012/01/Damn-Cool-Algorithms-Fountain...
