Zusammenfassung:The invention is a method of managing application (AP) execution in an electronic token (ET) comprising at least a first and a second microprocessors (MP1, MP2). One of the microprocessor is the master microprocessor when it has responsibility for application (AP) execution. Said method comprises the step of: selecting (E1) the first microprocessor as master microprocessor, then the step of starting (E2) application (AP) execution by the first microprocessor, then the step of transferring (E4, E12) the responsibility for application (AP) execution to the second microprocessor during the application (AP) execution.
