    University essay from KTH/Kommunikationssystem, CoS

    Author : Jens Christian Hillerup; [2013]
    Keywords : ;

    Abstract : Hash functions are a type of mathematical function that takes an input of arbitrary length and gives an output of fixed length, called a hash value. Many consider hash values to be sort of a “fingerprint” of some data, since they can be assumed to have unique outputs for any possible input. READ MORE
