Abstract (en)

[origin: WO2007128552A1] In a method for interchanging data between at least two applications stored on a portable electronic data storage medium, particularly a chip card, the applications are application processes (2a, 2b, 2c) during the data interchange, and the communication between the application processes (2a, 2b, 2c) is coordinated by means of an operating system (1) which is capable of multitasking and/or multithreading. In this context, the operating system (1) which is capable of multitasking and/or multithreading checks whether the application processes (2a, 2b, 2c) are authorized to interchange data with one another. Preferably, the data interchange takes place using memory areas which can be used for data interchange only by application processes (2a, 2b, 2c), such as main memory segments which are jointly accessible to the application processes (2a, 2b, 2c), processor registers or a stack memory.
