TRACE-CHECK Release 2022.2

DTLS support in PCAP trace analysis of service-based communication

Increased networking of onboard communication with backend systems, as well as new legal regulations, make it necessary to protect communication from cyber attacks.

The DTLS (Datagram Transport Layer Security) security protocol enables authentication and even encryption of vehicle communications, so that they are protected from tampering and interception. DTLS is based on the functionality of TLS, but uses the unsecured transport protocol UDP instead of TCP.


The current version of ECU-TEST supports the analysis of service-based communication with DTLS 1.2 from PCAP traces. In particular, key files exported with Wireshark can be reused. If you are interested in extending this feature (e.g. TLS support) please contact our support service.

Abort of trace analysis in the case of synchronization errors

Successful synchronization of multiple traces from diverse sources can be an essential prerequisite for their processing. If it is not possible to establish synchronization with the required accuracy, time-consuming post-processing of the recordings (trace merging and trace analysis) does not make sense either.

In the new version of ECU-TEST, therefore, the option to Continue on error has been added, in order to cancel post-processing in the event of an error, and free up valuable resources.


IP reassembling support for PCAP trace analysis

Especially when transmitting large amounts of data, it may not fit into a single IP data packet. In this case, the data is fragmented into several packets. The current version of ECU-TEST is able to reassemble these packet fragments from PCAP traces and analyze them as if they had been transmitted as a whole.

Apache Parquet Traces support for trace analysis

Apache Parquet is an open-source column-oriented recording format for high-performance analysis of large data sets. With ECU-TEST, it is now possible to analyze Parquet files (.parquet or .pqt).
