Abstract: An example operation includes one or more of generating a data frame for transmission via a controller area network (CAN) bus of a transport, the data frame comprising data stored in a plurality of fields, encoding at least one authentication bit into a value within a data field of the generated data frame, wherein the at least one authentication bit comprises a digital signature based on a predefined key for the at least one authentication bit, and transmitting the generated data frame with the at least one authentication bit that comprises the digital signature via the CAN bus.

Abstract: An example operation includes one or more of receiving, via a first communication channel between a sending device and a recipient device, a first partial encryption key from the receiving device, receiving, via a second communication channel between the sending device and the recipient device, a second partial encryption key from the receiving device, wherein the second communication channel comprises a different communication medium than the first communication channel, generating a transport key based on the first partial encryption key and the second partial encryption key received via the first and second channels, and encrypting data based on the generated transport key and transmitting the encrypted data to the receiving device.
