Abstract (en)
[origin: WO02082389A2] The invention relates to a method and a circuit for extracting a secret datum from an integrated circuit involved in an authentication procedure. The secret datum is obtained at least partially from a network of physical parameters that are linked to the production of the integrated circuit chip. Said secret datum is generated upon request and made ephemeral.
[origin: WO02082389A2] The invention relates to a method and a circuit for extracting a secret datum (s) from an integrated circuit involved in an authentication procedure by means of an external device that takes account of said secret datum. Said secret datum is generated upon request and made ephemeral.
