Abstract: The embodiments relate to a near field communication system including a plurality of near field communication devices which communicate with each other via a radio interface. During generation of a common cryptographic key between the near field communication devices of the near field communication system, at least one of the two near field communication devices monitors during generation of the cryptographic key via the radio interface in a generation period whether an additional near field communication device which could be a potential active attacker communicates with one of the near field communication devices via the radio interface. If such a suspicious type of communication is detected, generation of the common cryptographic key is optionally terminated.

Abstract: Method for providing a mesh key which can be used to encrypt messages between a first node and a second node of a mesh network, wherein a session key is generated when authenticating the first node in an authentication server, the first node and the authentication server or an authentication proxy server using a predefined key derivation function to derive the mesh key from said session key, which mesh key is transmitted to the second node.

Abstract: In a system (1) for transmitting RFID identifiers, which can be read from RFID tags (4), to an authentication server (6), at least one RFID protocol message, which is encoded in authentication messages, can be transmitted from an RFID reading unit (2A) to the authentication server (6).

Abstract: A message processing device for processing messages has at least one reception buffer, a message includes at least one authentication element and one message content. The message is received and stored in the reception buffer. A characteristic variable of a priority for security checking of the message is determined as a function of the message content. A processing sequence for further message processing for the security checking, taking into account the at least one authentication element of the messages in the reception buffer is defined and carried out as a function of the characteristic variable.

Abstract: In a method for the access control to an automation unit (01), access rights predetermined by the access control are dependant on the operating state of the automation unit (01), wherein at least during an emergency, expanded access rights in relation to normal operation are granted independently of the access rights during normal operation.

Abstract: A device for authorizing an online service during driving in a vehicle. Contents of an online service are authorized according to the vehicle state. The device includes an electronic control unit, a graphical output apparatus, and a communication interface. A system that includes the device and a server, which is not located in the vehicle and which is connected to the communication interface through a wireless connection for the exchange of data. A method, having the following steps: the vehicle state of the vehicle is detected. According to the vehicle state, it is checked if a requested online service or certain contents of a requested online service are authorized for display during driving. According to available or ascertainable data on the ability of the requested online service to be authorized during driving, the requested online service is either blocked or authorized in a limited or complete manner. The result is depicted on the graphical output apparatus.
