Abstract: A method of securely booting a computer system includes executing program code of at least one boot loader to load a kernel; verifying, during loading of the kernel, the program code of the boot loader after at least a part of the program code of the boot loader has been executed; and interrupting the booting if a result of the verifying of the program code of the boot loader indicates a manipulation of the program code of the boot loader.

Abstract: A method of executing a security-relevant application on a computer system in a secured environment includes establishing a data network connection via an internal network of the secured environment between the computer system and a server arranged in the secured environment; searching, by the computer system, for at least one predetermined file on the server after the data network connection has been established; verifying, by the computer system, a signature of the at least one predetermined file, if the at least one predetermined file has been found; executing, by the computer system, the at least one predetermined file if the verification of the signature was successful, wherein a system file is modified through the execution of the at least one predetermined file; and starting the security-relevant application after the at least one predetermined file has been successfully executed.

Abstract: A method of authenticating a user at a security device includes providing a first pattern on an authentication device capable of wireless data transmission; searching for authentication devices by the security device via a wireless data connection; loading the first patterns of all found authentication devices in a memory of the security device via the wireless data connection; detecting a second pattern by a detection device of the security device; comparing the detected second pattern to the loaded first patterns; and positively authenticating the user when the detected second pattern matches one of the loaded first patterns.

Abstract: A method for an autonomous rights administration component of a computer system includes recording devices of the computer system, determining unique identifiers for each recorded device, permanently storing the unique identifiers, defining a usage rights contingent and a usage rights requirement and activation of at least one application function on the basis of a comparison of the usage rights contingent with the usage rights requirement. The invention furthermore relates to an autonomous rights administration system and a device for a rights administration of this type.
