摘　　要：随着ICV(智能网联汽车)产业的快速发展,车与人、车与车以及车与外部环境的数据交换成为常态,汽车安全受到严重威胁,研究汽车安全认证方法则显得至关重要.车载PEPS(无钥匙进入及启动系统)和EMS(发动机管理系统)的安全认证决定整车安全性能,是保证汽车安全运行的前提条件.目前业界广泛采用128 bits AES算法实现PEPS和EMS的安全认证,而由于AES密钥生成和密钥调度算法较国密算法SM4复杂,加解密时间较长,且算法实现的代码量较大,占用过多的MCU资源,因此,本文提出将国密SM4算法应用于车载PEPS和EMS的安全认证,缩短加解密时间,有效提高数传效率,同时采用高级语言实现该算法并移植到国产MCU GD32F103,实现产品国产化,降低成本.将国密算法SM4进行推广,为ICV安全认证提供研究基础.With the rapid development of ICV(Intelligent Connected Vehicle)industry,data exchange between vehicle and human,vehicle and vehicle as well as between vehicle and external environment has become common,which imposes serious threat to automobile security.Security certification of vehicle PEPS(Passive Entry Passive Start)and EMS(Engine Management System)is the prerequisite to ensure the safe operation of the vehicle.How⁃ever,the widely used 128 bits AES for PEPS and EMS security certification is complex in algorithm,time consuming in encryption and decryption,and occupies more MCU resources,compared with encryption algorithm SM4.Here,the SM4 algorithm is used to carry out security certification of vehicle PEPS and EMS,which can shorten the encryption and decryption time,and effectively improve the data transmission efficiency.Then,it is implemented by advance language and transplanted to domestic MCU GD32F103.The proposed approach applies encryption algorithm SM4 and provide a research basis for ICV security certification.
