Symmetric key exchange via TLS on CAN bus interface for multiple devices. The key exchange is configured to elect a master PCA pump for a CAN bus network and prevent two PCA pumps from being master. Upon joining the CAN bus network PCA pumps exchange their MAC IDs with the PCA pumps in the CAN bus network. Once a bootstrap timeout ends, each PCA pump compares all MAC IDs to determine if it should advance to the voting stage. If the PCA pump has the lowest MAC ID, the PCA pump enters the voting stage. During the voting stage, the PCA pump sends master requests prompts to all the PCA pumps in the network. If the PCA pump's internal vote counter reaches a count of three the PCA pump becomes key master.
