Abstract
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.
Claims16
A method of managing application execution in an electronic token, said token having at least first and second microprocessors, one of the microprocessor being a master microprocessor when it has responsibility for application execution, said method comprising the following steps:
- selecting the first microprocessor as the master microprocessor,
- starting application execution by the first microprocessor, and
- transferring the responsibility for application execution to the second microprocessor during the application execution.
An electronic token containing
- at least first and second microprocessors,
- a memory containing an application, wherein, when the application execution is started by a first microprocessor having the responsibility for application execution, the responsibility for application execution is transferred to a second microprocessor during the application execution.
