    摘要: At least one embodiment of the present invention relates to supporting a safety-oriented system, with the safety-oriented system including safety-critical software components and non-safety-critical software components. In this method, a possibility of a safety-critical software component and a non-safety-critical software component influencing each other is identified and a set of technical measures for preventing the possibility of influencing is defined. In this way, an absence of feedback from non-safety-critical software components to safety-critical software components is both verified and also ensured by at least one embodiment of the present invention.

    摘要: A method and system for transmitting a message in real time between users in a closed network of a vehicle (1), in particular a rail-mounted vehicle, are provided, wherein safety-relevant real-time data (D) of a message (N), including a transmitter ID of a transmitter (3) within the closed network, is encrypted (S1) using a private key (KprivA) of the transmitter (3) in order to generate an encrypted message (N′); the encrypted message (N′), together with the unencrypted transmitter ID of the transmitter (3), is transmitted (S2) from the transmitter (3) to a receiver (4) within the closed network via a vehicle bus (2), and the encrypted message (N′) is decrypted by the receiver (4) using a public key (KpublicA) of the transmitter (3) identified by the received, unencrypted transmitter ID in order to retrieve the unencrypted message (N). The received transmitter ID is compared with the transmitter ID contained in the retrieved message (N) in order to determine whether the message (N) has been transmitted correctly.

    摘要: A system for monitoring a security-related system has a monitoring device on which a first process occurs. The monitoring device generates a monitoring result which is transmitted to another device that forms at least part of the security-related system. Accordingly, a second monitored process of the security-related system returns the received monitoring result to the first process for testing in order to calculate a processing result.
