More Information
Summary:A vehicle receives a first portion of content via ATSC broadcast, generates a random nonce, responsive to receiving the content, and sends the nonce and a request for content verification to a remote server. The vehicle receives a message from the remote server indicating whether the first portion of content is likely valid, the message including a second portion of content and a hash value when the content is likely valid. The vehicle then calculates a second hash value, using the random nonce and the first portion of content. The vehicle compares the second hash value to the first hash value, and responsive to the second hash value matching the first hash value, combines the second portion of content and the first portion of content to create combined content. The vehicle then uses a security strategy to convert the combined content into utilizable content, and utilizes the content.
