Abstract: Aiming at data security problem of industrial chain collaboration public service platform based on Software-as-a-Service(SaaS)，data security solutions of public service platform were designed. The solutions realized confidentiality of enterprise data storage by combining non-symmetric encryption technologies and Web Service technologies, and achieved data integrity, network transmission confidentiality and non-repudiation by using non-symmetric encryption technologies, Hash technologies and digital signature technologies. Finally, the feasibility and effectiveness of the solution were confirmed through the solution implementation, security analysis and feasibility analysis.

Key words: industrial chains, collaboration public service platform, data security, encryption technology, Web Service
