Today, in-vehicle innovation has brought us to a newer level of the incorporated system being explored and further developed to gain the access of controlling vehicles in our modern life. The typical approach would be utilizing the access of control to the various types of systems in a vehicle implementing the electronic control units (ECUs). These ECUs can be used to interconnect between various vehicle systems which provide convenience of the implementation to application software. Controller Area Network (CAN) bus was designed to enforce the essential needs of the reliability, safety and the real time capability in the network. Despite the absence of the encryption which exploit the vulnerability to the man-in-the-middle attacks eavesdropping or interception of data packets. Nonetheless, precautionary measures is to be taken to prevent the leak of the data transmission and to enforce the security for the CAN bus protocol. Since security has become the main concern for the in-vehicle network, we will enhance our priority on the integrity and the authenticity for CAN Bus by implementing the encryption and authentication techniques (AES-CCM). AES-CCM (32 bit MAC) which is known as the Advancement Encryption Standard-Counter with CBC MAC are commonly propose to the design as an assurance to ensure that the transmission of CAN bus message in ciphertext with valid authentication. These processes can be evaluated by interconnection of the two nodes CAN. This enhanced design of the security involves in the coding of the authenticated encryption algorithm onto MC9S12DGMPVE CAN Bus evaluation board using CodeWarrior IDE, followed by achieving the objective of communication between two nodes CAN bus by sending and receiving message on the end node. Other improvement method on providing higher level of authentication can be look into the completion of the projects to assure the enhanced security in the two nodes CAN bus for future generation of vehicular network.
