Abstract
In one embodiment, an authentication method features the generation of an initialization vector at a first electronic device and the determination at the first electronic device whether the initialization vector falls within a first group of initialization vectors. The first group includes a plurality of initialization vectors solely used in connection with an authentication sequence. Information is encrypted using in part the initialization vector for return to a second electronic device if the initialization vector falls within the first group.
