The invention discloses a method for protecting a secret key cryptographic scheme including the steps of: generating a set of strong key byte pairs for a given algorithm; selecting from the set a predetermined number of strong key byte pairs to at least partly from a secret key of predefined length; and programming an encoding device with the secret key. The invention extends to programming the secret key on a SIM card operable on a GSM network. |
