Abstract: According to certain general aspects, the present embodiments relate generally to securing communication between ECUs. In some embodiments, this can be done by utilizing the excess space in the CAN protocols. According to certain other aspects, security features such as sender authentication and message originality can be implemented at the protocol level, reducing the delays associated with implementing security features at higher levels in the communication stack. Additionally, the complexity of the security configuration is minimized by implementing the security features in hardware.

Abstract: A method for run time zero byte compression of data on a communication bus of a vehicle includes determining a number of zero byt.es provided in a data frame. When there are enough zero bytes, an encoding byte is generated that maps the locations of the zero bytes in the data frame. A data length code related to the number of non-zero data bytes and the encoding byte is provided in a device header. The data length code has a value less than an uncompressed data frame. The compressed data frame is transmitted with the encoding byte and the uncompressed non-zero data bytes. To decompress the compressed data frame, the encoding byte maps the locations of the zero bytes for a data frame. The non-zero data bytes are then provided at the proper locations to recreate the data frame.
