Abstract
Abstract In this method, at least one common secret key is generated by two terminals (1a, 1b) by means of a PKD (PKD = Public Key Distribution) method. To authenticate the secret key, a public characteristic value is formed in each case in the two terminals (1a, 1b) from the common secret key and these two characteristic values are compared with one another via a separate, public auxiliary channel (4). According to a preferred embodiment, the public characteristic value is generated using a one-way function. The characteristic value is advantageously shorter here than the secret key. <IMAGE>
