MICROPROCESSOR SYSTEM WITH SECURED RUNTIME ENVIRONMENT

摘要

Microprocessor system that is implemented or can be implemented in a mobile terminal and comprises: a normal operating system designed to generate and maintain a non-secure runtime environment and a security operating system designed to generate and maintain a secured runtime environment, and an operating system interface between the normal operating system and the security operating system, said operating interface being designed to control communication between the non-secure runtime environment and the secured runtime environment on the operating system level, and at least one filter interface that is designed to securely control communication between the non-secure runtime environment and a secured runtime environment on a level different from the operating system level.

1. A microprocessor system, implementable or implemented in a mobile terminal and comprising:
a normal operation system (HLOS), which is designed for generating and maintaining an insecure runtime environment, a security operating system (MobiCore), which is designed for generating and maintaining a secure runtime environment, and an operating system interface (MobiCore driver) between the normal operating system (HLOS) and the security operating system (MobiCore), said operating system interface being designed to securely control communication between the insecure runtime environment and the secure runtime environment at the operating system level, characterized by at least one filter interface (virtual I2C driver; TLC), which is designed to securely control communication between the insecure runtime environment and the secure runtime environment at a level different from the operating system level.
