Abstract

In a protocol (P) in which no data fields are integrated for transmitting key material (SM), a device can be subsequently integrated to form a key-exchange mechanism (SAM) by introducing the key material (SM) into a random-number field (ZF) present in the protocol (P) and transmitting it to the other computer unit in each case.
