Circuit arrangement for controlling access to cryptographic function of cryptographic unit, has cryptographic unit for providing cryptographic function and access control interface examines access requirement of application computer program

摘要

The circuit arrangement has a cryptographic unit (206), which provides a cryptographic function. An access control interface examines an access requirement of an application computer program for a cryptographic function. The access control interface examines whether the application computer program is authorized to access the cryptographic function of the cryptographic unit then the cryptographic function of the cryptographic unit is accessed. If the application computer program is not authorized to access the cryptographic function of cryptographic unit, then the access request is declined. Independent claims are also included for the following: (1) a communication device with a circuit arrangement (2) a method for starting a circuit arrangement (3) a method for operating a circuit arrangement (4) a computer program product for starting a circuit arrangement.
