COMMUNICATION ARRANGEMENT AND METHOD FOR GENERATING A CRYPTOGRAPHIC KEY

摘要

In various embodiments, a communication arrangement is provided. The communication arrangement includes a first communication device, and a second communication device. The first communication device includes a processing element configured to read out a device-specific number from a component of the first communication device, to mask the device-specific number by the random number and to transmit the masked device-specific number to the second communication device. The second communication device includes a mapping element configured to map the masked device-specific number to a codeword of a code and to transmit the codeword to the first communication device. The first communication device further includes a key generator configured to demask the codeword by the random number and to determine a cryptographic key based on the demasked codeword.
