Vehicle, apparatus, computer program, and method for a data processing circuit and for executing applications

A non-transitory computer-readable medium storing computer-executable instructions which, when executed by a processor, cause a data processing circuit for executing applications including at least one safety-relevant application and at least one non-safety relevant application using a same operating system, OS, and memory, by performing operations comprising:

• obtaining first memory information on a predefined memory space allocated to the safety-relevant application;
• obtaining second memory information on a memory space for the non-safety-relevant application;
• and
• applying a monitoring operation for checking, based on the first and second memory information, if the non-safety-relevant application uses memory space allocated to the safety-relevant application to verify spatial freedom-from-interference, FFI, wherein the monitoring is executed in a Trusted Execution Environment, TEE.

An automotive vehicle comprising:

• one or more interfaces for communication;
• and
• a data processing circuit for executing applications including at least one safety-relevant application and at least one non-safety relevant application using a same operating system, OS, and memory, the data processing circuit being configured to perform operations comprising:
• obtaining first memory information on a predefined memory space allocated to the safety-relevant application;
• obtaining second memory information on a memory space for the non-safety-relevant application;
• and
• applying a monitoring operation for checking, based on the first and second memory information, if the non-safety-relevant application uses memory space allocated to the safety-relevant application to verify spatial freedom-from-interference, FFI, wherein the monitoring is executed in a Trusted Execution Environment, TEE.
