Aiming at the real time, reliability and security of test and launch control system for missile, a Missile-CAN communication protocol for missile test and launch control system is proposed. The 29 bit identifier and data communication mode of the message are defined in detail, and the management mechanism of the CAN network is formulated. In the security of communication, AES encryption algorithm is used to encrypt transmission messages. The hardware platform of the experiment system is introduced and the method of software realization is designed. The simulation experiment results show that the communication quality of the network is good and the utilization rate of the bus conforms to the real-time requirement of test and launch control system for missile, and the feasibility of the Missile-CAN protocol is verified.？
