摘要 <p>The method involves storing assigned cryptographic key in transaction receiver (C1) and separate processing element (AE). Vehicle image is recorded. Associated control transaction is generated in control station (TE). Recorded image, control transaction, random key and authentication data are sent to transaction receiver. Received recorded image is encrypted into nominal authentication data with random key and cryptographic key. Received authentication data is compared with nominal authentication data. Received control transaction is validated, if datasets are identical.</p>
