Abstract
A method comprises obtaining a plurality of variable size chunks of data, calculating a first hash for each variable size chunk of data, determining a length representation for each variable size chunk of data, determining a second hash of a subset of each variable size chunk of data, and forming a signature of each variable size chunk of data that is comprised of the first hash, the length representation and the second hash.
