摘要： The invention relates to a method for securely transmitting data, particularly between a tachograph (51) of a goods-carrying vehicle and memory cards (50). A first node (T1) comprises a memory (6, 22) with entries (31-35) containing identifiers (4) and security certificates (Cert) of second nodes (T2). Methods for securely transmitting data are increasingly gaining importance and are often accompanied by a high amount of computing. As a result, the aim of the invention is to reduce the computing time without forfeiting security. To this end, the first node (T1) obtains an identifier (4) from the second node (T2) and compares it with stored identifiers (4). In the event of a matching identifier (4), a security certificate (Cert) assigned to this identifier (4) is provided as a basis for a subsequent data transmission, and in the event the identifier (4) does not match, a security certificate verification is carried out.
