Abstract: For the possible security hidden trouble during process of industry chain collaboration platform and enterprise information integration,a mathematical model on multi-source information dynamic integration security was established.A multi-source information dynamic integration security solution of Software as a Service(SaaS)collaborative platform oriented to industrial chain was proposed.The digital abstract was generated with Hash algorithm to realize the integrity of the data in the transmission process of Web service.By using asymmetric encryption technology and digital signature technology,Web service network transmission security and non repudiation of sending message were realized.Taking cooperation enterprise inventory information an example,through the identity authentication during the wizard installation process for platform collaboration enterprise and the verification of integrity and confidentiality during the process of registration service information,the usability and effectiveness of the proposed method was proved.
