An example vehicle electronic control unit includes a first processor and a second processor. The first processor, when unlocked, provides diagnostic information. The second processor sends a seed value to a diagnostic tool. Additionally, the second processor, in response to receiving a second key, unlocks the first processor. The second processor, after receiving a first verifier, decrypts the first verifier to generate a new key, replaces a current key with the new key, and sends a second verifier to the diagnostic tool."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"End-to-end vehicle secure ECU unlock in a semi-offline environment","description":"Method and apparatus are disclosed for end-to-end vehicle secure ECU unlock in a semi-offline environment.
