Keeping a dual-interface object in fully simultaneous operation
First Claim
1. A method for sustaining operation of a smart portable object provided with a processor block having at least two communications and/or power supply interfaces that are contact and/or contactless interfaces, said method including a step for reinitializing the processor block wherein said method includes at least one step for delaying and/or faking re-initialization in the event that a call/communication or an application is being processed by the processor block.

Abstract
The invention relates to the operational maintenance of an intelligent portable object (1) which is provided with a processing unit (6) having at least two communication and/or feed interfaces either with or without contacts. The method comprises a reinitialization step (MaZ) for the processing unit (6). The method is characterized in that it comprises at least one delay and/or reinitialization simulation step if a communication or application is in the process of being processed by the processing unit. The invention also relates to an associated device.

13. A device for sustaining fully simultaneous operation of a smart portable object having a dual interface, and provided with a processor block;
- said object being suitable for communicating with at least one electronic data transmission terminal for electronically transmitting data via a contact interface in compliance with Standard ISO7816.3, and also in contactless manner via a contactless interface and in compliance with another, contactless standard;
said device making provision as follows;
the terminal is connected to the object via the contact interface so as to be made secure by the object;
in the dual interface operating state, the contact interface and the contactless interface operate at the same time;
the processor block including reset circuits for the purpose of reinitializing it when the contact interface is reset;
said device wherein it includes at least transaction-sustaining means, including at least one element for delaying and/or faking re-initialization ordered by the contact interface during a reset transition aiming to reinitialize the processor block. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 25, 26)
