1. A method for securing content to be used by a device comprising designating a plurality of portions of said content;

  • storing a first value on said device;

    generating a first signature on a first portion of said content, said first signature comprising a component which encrypts a second value such that said second value can be recovered using said first value;

    generating a second signature on a second portion of said content, said second signature comprising a component which encrypts a third value such that said third value can be recovered using said second value; and

    if more than two portions, generating other signatures that each include a component which encrypts a next value to be used by a next portion such that said next value can be recovered using a previous value recovered from a signature on a previous portion;

    wherein said first value can be used to recover said second value from said first signature, said second value can be used to recover said third value from said second signature and, if necessary, said next values are recoverable using said previous values, such that a final value recovered from a respective signature on a last of said portions can be compared with said first value to authenticate said plurality of portions simultaneously.
