Abstract
Disclosed is a secure element used in a host terminal, including several communication interfaces for communication with the outside, several applications and a runtime environment. At least two applications are issuer security domains instantiating two GlobalPlatform configurations, typically GP configurations UICC and eSE. The runtime environment is configured to receive a command over a communication interface, to determine a target application for executing that command according to that communication interface and to send, over that same interface, a response to the command. This ensures the independence of the two configurations by providing that the runtime environment only authorizes access to an application resource of the secure element for executing the command by the target application if that application resource is associated with the communication interface for receiving the command.
