Abstract: An embedded electronic system includes a volatile memory and a processor configured to execute a low-level operating system that manages allocation of areas of the volatile memory to a plurality of high-level operating systems. Each high-level operating system executes one or more of applications. The volatile memory includes a first portion reserved for execution data of a first application and a second portion intended to store execution data of a second application. The system is configured so that once the execution data of the first application are loaded in the first portion, the low-level operating system forbids unloading of the execution data of the first application from the first portion so that the execution data of the first application remain in the volatile memory in case of a deactivation or of a setting to standby of the first application.

Abstract: A tamper resistant device can be used for an integrated circuit card. The device includes memory storing a first security domain that includes a telecommunication profile and a second security domain that includes an application profile. A first physical interface is configured to be coupled to a baseband processor configured to operate with a mobile telecommunications network. A second physical interface configured to be coupled to an application processor. The first physical interface configured to allow the baseband processor to access the telecommunication profile and the second physical interface is configured to allow the application processor to access the application profile. The tamper resistant device is configured to enable accessibility to the application profile if corresponding commands are received at the first interface and to enable accessibility to the telecommunication profile if corresponding commands are received at the second interface.
