RUNTIME ENVIRONMENT FOR A MOBILE TERMINAL WHICH ALLOWS A SECURITY SERVICE TO BE PROVIDED

摘要

The invention relates to a runtime environment for a mobile terminal (D), comprising a normal runtime environment (REE) for client applications (CA) and a secure runtime environment (TEE) for trusted applications (TA). Service requests can be transmitted from the normal (REE) to the secure runtime environment (TEE). In response, security services can be transmitted from the secure (TEE) to the normal runtime environment (REE). The secure runtime environment (TEE) is implemented as an external secure runtime environment (TEEaaS) on a server (S) arranged outside of the terminal. The normal runtime environment (REE) and the external secure runtime environment (TEEaaS) are designed to carry out a client/server protocol between the normal execution environment (REE) and the external secure runtime environment (TEEaaS), for example a remote procedure call, in order to establish the communication connection.
