摘　　要：针对普通CAN总线的安全缺陷,提出基于AES-CCM算法的安全CAN总线协议。分别通过对数据帧CRC场和扩展帧ID场的利用,提出两种不同的方案,使CAN总线具有机密性、可认证性和抗重放攻击的能力。利用2块飞思卡尔MC9S12XF512开发板作为试验平台,对所提出的安全CAN总线协议进行了分析与评测,结果表明,当总线频率设定为128MHz时,安全CAN总线单帧报文的收发可在2 ms内完成,同时该协议表现出良好的可靠性。This paper proposed an AES-CCM algorithm based security CAN bus protocol for offsetting the security defects of traditional CAN bus.By using the data frame’s CRC field and extended frame’s ID field respectively,the paper proposed two different methods to make CAN bus have the abilities of confidentiality,authenticity and anti-replay attack.Two Freescale MC9S12XF512 development boards were used as the experimental platform,the proposed security CAN bus protocol was analyzed and evaluated.The results show that when CAN bus is set at 128 MHz,security CAN bus singleframe message can be received and dispatched within 2 ms,whereas this protocol shows good reliability.
