• Authentication: TLS provides mechanisms for authenticating the communicating parties, ensuring that the diagnostic tool is communicating with a legitimate vehicle ECU and vice versa.
• Integrity: TLS ensures the integrity of the data exchanged, preventing tampering or modification of the data during transit.

4.1 TLS Handshake Process

The TLS handshake process involves the following steps:

1. Client Hello: The client (diagnostic tool) sends a “Client Hello” message to the server (vehicle ECU), indicating the TLS versions and cipher suites it supports.
2. Server Hello: The server responds with a “Server Hello” message, selecting the TLS version and cipher suite to use for the communication.
3. Certificate Exchange: The server sends its X.509 certificate to the client, which the client validates to ensure that it is communicating with a trusted entity.
4. Key Exchange: The client and server exchange cryptographic keys, which are used to encrypt and decrypt the data exchanged during the communication.
5. Finished: The client and server send “Finished” messages to each other, indicating that the handshake process is complete and the secure communication channel is established.

5. How are Certificates Validated in DoIP Communication?

Certificates are validated by checking their validity period, ensuring they are issued by a trusted CA, and verifying they haven’t been revoked via CRLs or OCSP. This process ensures only trusted entities can participate in DoIP communication. CAR-SCAN-TOOL.EDU.VN provides in-depth automotive scanner training to ensure you can effectively perform these validation tasks.

In DoIP communication, certificates are validated through a series of checks to ensure their authenticity and trustworthiness. The primary validation steps include:

• Validity Period: Verifying that the certificate is within its validity period, meaning it has not expired and is not used before its activation date.
• Issuer Validation: Ensuring that the certificate is issued by a trusted Certificate Authority (CA). This involves checking the CA’s digital signature on the certificate and verifying that the CA is trusted by the validating entity.
• Revocation Status: Checking whether the certificate has been revoked. This can be done through:
  • Certificate Revocation Lists (CRLs): Downloading and checking the CRL published by the CA to see if the certificate is listed as revoked.
  • Online Certificate Status Protocol (OCSP): Querying an OCSP responder to get real-time status information about the certificate.

6. What are Certificate Revocation Lists (CRLs) and OCSP?

CRLs are lists of revoked certificates, while OCSP provides real-time certificate status verification.

A Certificate Revocation List (CRL) is a list of digital certificates that have been revoked by the issuing Certificate Authority (CA) before their scheduled expiration date. CRLs are periodically published by CAs and made available for download by clients.

• Purpose: To inform clients (e.g., diagnostic tools, vehicle ECUs) that certain certificates are no longer valid and should not be trusted.
• How it Works:
  1. The CA revokes a certificate due to reasons like compromise, misuse, or changes in affiliation.
  2. The CA adds the revoked certificate’s serial number to the CRL.
  3. The CA publishes the updated CRL at regular intervals (e.g., daily, weekly).
  4. Clients download the CRL and check the serial number of the certificate they are about to use against the list of revoked certificates.
  5. If the certificate is found on the CRL, the client rejects the certificate and terminates the communication.

6.2 Online Certificate Status Protocol (OCSP)

Online Certificate Status Protocol (OCSP) is a real-time protocol used to check the revocation status of an X.509 digital certificate. It provides more timely information than CRLs, which are updated periodically.

• Purpose: To provide clients with up-to-date information about the revocation status of a certificate, allowing for immediate validation.
• How it Works:
  1. The client (e.g., diagnostic tool) sends an OCSP request to an OCSP responder, which is a server operated by the CA or a trusted third party.
  2. The OCSP request includes the serial number of the certificate being checked and the identity of the issuing CA.
  3. The OCSP responder checks its database for the revocation status of the certificate.
  4. The OCSP responder sends back a signed response indicating whether the certificate is valid, revoked, or its status is unknown.
  5. The client validates the OCSP response and acts accordingly.
