• CAN (Controller Area Network): A communication protocol commonly used in vehicles that can be secured using techniques such as message authentication codes (MACs) and encryption.

3.3. TLS (Transport Layer Security)

TLS is a cryptographic protocol that provides secure communication over a network. It is commonly used to secure web traffic (HTTPS) and can also be used to secure diagnostic communication protocols such as DoIP. TLS provides:

• Encryption: Encrypts data transmitted between the diagnostic tool and the vehicle to protect it from eavesdropping.
• Authentication: Authenticates the diagnostic tool and the vehicle to prevent unauthorized access.
• Integrity: Ensures that data has not been tampered with during transmission.

3.4. Message Authentication Codes (MACs)

Message Authentication Codes (MACs) are cryptographic hash functions that are used to verify the integrity of messages. They can be used to secure CAN communication by generating a MAC for each message and including it in the message. The receiver can then verify the integrity of the message by recalculating the MAC and comparing it to the MAC included in the message.

3.5. Authentication and Authorization Mechanisms

ECOM implements various authentication and authorization mechanisms to ensure that only authorized diagnostic tools are granted access to ECU functions. These mechanisms include:

• Username and Password: Requires diagnostic tools to authenticate themselves using a username and password.
