摘　　要：针对高速铁路动车组(简称:动车组)车载数据在传输过程中面临的安全性问题,提出一种基于国家商用密码(简称:国密)算法的安全传输方案。文章采用SM2、SM3、SM4等算法,进行数据加密、数字签名及认证和消息摘要,以增强动车组车载数据传输的机密性、完整性、真实性和不可否认性。通过密钥生命周期管理,确保密钥在生成、存储、使用和销毁各过程中的安全性。该方案能够为提升动车组车载数据传输的安全防护能力提供技术支持。This paper proposed a secure transmission scheme based on the national commercial cryptographic algorithm to address the security issues faced by high-speed railway Electric Multiple Units(EMU)onboard data during transmission.The paper used algorithms such as SM2,SM3,and SM4 for data encryption,digital signature and authentication,and message summarization to enhance the confidentiality,integrity,authenticity,and non-repudiation of high-speed train onboard data transmission,ensured the security of keys during the generation,storage,use,and destruction processes through key lifecycle management.This solution can provide technical support for enhancing the security protection capability of on-board data transmission for EMU.
