摘要：The embodiments relate to methods and apparatuses for producing securetransmission of a message. The methods are based on production of a basic key that isused for producing respective transmitter keys for a plurality of transmitters. For theascertainment of the receiver keys by respective receivers, the basic key is transmitted tothe receivers, which for their part are able to ascertain a receiver key for checking theintegrity of the message from a respective transmitter on the basis of the basic key andan identifier for the transmitter. The receiver ascertains a cryptographic checksum, which,in the course of the integrity check, is compared with a cryptographic checksum that hasbeen produced by the transmitter and sent along by the respective message. Theembodiments may be used within the context of automation and sensor networks.
