摘要
The invention concerns a method for protecting a logic circuit (11) contained in a logic unit (1) against attacks external to said unit. Said method comprises the following operations: generating in the unit (1) a programming instruction of a programmable logic circuit (12) comprised in the logic circuit (11); loading in the programmable logic circuit (12) in response to the programming instruction, a specific programming configuration (C1) selected among a plurality of configurations different from one another (C1, , C4); programming the programmable logic circuit (12) in accordance with the specific configuration (C1).
