Abstract
A device and a method of authenticating an electronic device are described. The method may comprise transmitting a token value and a parameter value to the electronic device and selecting a private key within the electronic device using the parameter value. The token value may be processed with a method selected by the parameter value to generate a processed token. The processed token may be compared with an expected processed token and the electronic device may be authenticated if the processed token compares favorably with said expected processed token.
