Abstract

A method and a system for cheking the integrity of a message, such as software or data, in relation to an original message to which they are supposed to correspond. By applying an algorithm (A) to at least one part of the original message, at least one signature (S1,S2... Sm) of this part is calculated and memorized in a storage area (10) of a portable object (1) which contains processing circuits (11) capable of implementing the algorithm (A). In order to check the integrity of a message, at least one signature of one part of the message is calculated by the processing circuits (11) of the portable object, by implementing the algorithm (A), and is compared with a signature of the original message to which it is supposed to correspond and memorized in the storage area (10).
