Abstract
The invention relates to a method for interchanging data between a secure runtime environment (SWd), in which a number of secure applications (TL) can be executed, and a non-secure environment (NWd) of a microprocessor unit (MP), in particular in a mobile terminal, in which application data (AD) and control data (MCP, NQ) are transmitted via different buffers.

A method for interchanging data between a secure runtime environment (SWd), in which a number of secure applications (TL) can be executed, and a non-secure environment (NWd) of a microprocessor unit (MP), in particular in a mobile terminal, in which application data (AD) and control data (MCP, NQ) are transmitted via different buffers.
A microprocessor unit with a secure runtime environment (SWd) and a non-secure environment (NWd), which unit is configured in such a manner that application data (AD) and control data (MCP, NQ, FC) are transmitted via different buffers in order to interchange data between the secure runtime environment (SWd) and the non-secure environment (NWd).
