Abstract: Aiming at the possible security problems of submission,storage and invocation of collaborative enterprise registration information,and the integration and transmission of accessory inventory information web services in the process of dynamic integration of multi-source parts inventory information on the automotive industry chain collaborative SaaS platform,the multi-source parts information dynamic integration security model of SaaS platform was built,and the abstract mathematical description for model was implemented.The secure integration of accessory inventory information was realized through the proposed security signature technology,encryption algorithm,key distribution scheme and calling strategy.The security and feasibility analysis of the proposed model and algorithm were carried out to verify the availability and effectiveness of the security integration scheme.

Key words: SaaS platform, parts inventory information, signature technology, encryption algorithm, key distribution, automobile industry chain

摘要： 针对汽车产业链协同SaaS平台多源配件库存信息动态集成过程中协作企业注册信息的提交、存储、调用,以及配件库存信息Web服务集成传输等环节可能存在的安全问题,构建了SaaS平台多源配件信息动态集成安全模型,并对模型进行了抽象数学描述。提出的安全签名技术、加密算法、密钥分配方案和调用策略等实现了配件库存信息的安全集成。对所提模型和算法进行了安全性和可行性分析,验证了安全集成方案的可用性和有效性。
