According to automotive cybersecurity expert Dr. Stefan Lang, “Dynamic addressing adds a layer of complexity that significantly raises the bar for potential cyber threats targeting vehicle ECUs.”

Challenges Posed by Dynamic Addressing

Working with dynamic addresses poses unique challenges for diagnostic tools:

• Discovery: The tool must first discover the current address of the ECU.
• Configuration: The tool must be configured to use the correct address each time it communicates with the ECU.
• Synchronization: The tool must maintain synchronization with the ECU to ensure communication remains reliable.

2. Vediamo’s Approach to Dynamic Diagnostic Addresses

Vediamo, a powerful diagnostic tool used extensively in the automotive industry, handles dynamic addresses through a combination of intelligent algorithms and configurable settings.

Address Resolution Techniques

Vediamo uses several techniques to resolve dynamic addresses:

• Seed-Key Exchange: A secure method where the diagnostic tool requests a “seed” from the ECU, which is then used to calculate a “key” for unlocking diagnostic access.
• Service 0x22 (Read Data By Identifier): Used to read the current diagnostic address from a specific memory location within the ECU.
• UDS (Unified Diagnostic Services) Protocol: A standardized protocol that includes services for reading and writing diagnostic data, including addresses.

Configuration Options in Vediamo

Vediamo allows users to configure various parameters to handle dynamic addresses effectively:

• Communication Parameters: Setting up the correct baud rate, CAN IDs, and timing parameters.
• Security Access: Configuring the seed-key exchange algorithm and security levels.
• Diagnostic Sessions: Selecting the appropriate diagnostic session mode (e.g., extended diagnostic session) to enable access to dynamic addressing features.

Practical Example: Reading a Dynamic Address with Vediamo

Here’s a step-by-step example of how to read a dynamic address using Vediamo:

1. Establish Connection: Connect Vediamo to the vehicle’s diagnostic port.
2. Select ECU: Choose the ECU you want to communicate with.
3. Initiate Diagnostic Session: Start a diagnostic session using the appropriate session mode.
4. Send Service 0x22 Request: Send a request to read the data identifier (DID) that contains the dynamic address.
5. Interpret Response: Analyze the response from the ECU to extract the current dynamic address.
