1. A method for identifying an entity, comprising the steps of:
- computing, by a portable device, a dynamic identification message for the entity, wherein the dynamic identification message is entirely variable;
communicating the dynamic identification message to an identification station;
receiving, by the identification station, the dynamic identification message; and
interpreting, by the identification station, the dynamic identification message in order to identify the entity.

Abstract
An authentication system is provided that includes a portable device and a decryption node. An individual uses the portable device, such as a portable device like a cell phone to compute a challenge and a response. The challenge and response is sent to a decryption node. In response, the decryption node computes a presumed response and compares the presumed response to the response of the portable device, in order to authenticate the individual associated with the portable device.

9. A method for identifying one of a plurality of entities, comprising the steps of:
-
associating a constant string to at least one of the plurality of entities, wherein the associated constant string is unique to that entity; computing, by a portable device, a dynamic identification message, wherein the computing process of the dynamic identification message uses the constant string associated to the entity; communicating the dynamic identification message to an identification station; receiving, by the identification station, the dynamic identification message; and interpreting, by the identification station, the dynamic identification message in order to identify the entity. - View Dependent Claims (10, 11, 12, 13, 14)
