Abstract: A processing circuit is coupled to imaging devices through multiple data communication links. Each data communication link couples at least one imaging device with the processing circuit. The processing circuit is configured to determine when a change is required in a first data protection configuration that protects first image data transmitted over a first data communication link, and determine a second data protection configuration to be used when second image data is transmitted from a first imaging device over the first data communication link to an image processing circuit. The first data protection configuration or the second data protection configuration provides a partial integrity mode of data protection for frames of image data transmitted over the first data communication link. The partial integrity mode protects some, but not all frames of image data transmitted over the first data communication link using a message authentication code.
