Describe the exclusive OR function.

What will be an ideal response?


The exclusive OR (XOR) function is used in cryptography as a linear mixing function to combine values. For example, the output of other primitive ciphers can be combined with an XOR function to produce a pseudorandom value on which another cipher performs additional operations. An XOR function is based on binary bit logic and results in a logical value of true if only one of the operands has a value of true. So, for example, if x and y are the same (both true or both false), the XOR output is 0 (false). If x and y are different, the XOR output is 1 (true).
