Abstract: Aiming at the data security problems existed in industrial chain coordination Software as a Service (SaaS) platform,the data security model for industrial chain collaborative SaaS platform was proposed,and the formalized description,framework and implementation process of the proposed model were given.Based on transfer secure module and storage secure module respectively,the security of data transmission and storage was implemented.Through the theoretical and experimental evaluation,the proposed model could meet the data security requirements of industrial chain collaborative SaaS platform,and the impact on overall performance of platform was relatively small.

Key words: industrial chain, software as a service, data security, encryption technology

摘要： 针对产业链协同SaaS平台可能存在的数据安全问题,提出了面向产业链协同SaaS平台的数据安全模型,并给出了所提模型的形式化描述、框架及实现过程。该模型分别利用传输安全模块和存储安全模块实现了数据的安全传输与存储。理论和实验评估表明,该模型能够满足产业链协同SaaS平台的数据安全需求,并对平台的总体性能影响较小。
