Introducing secure data transmission scheme in a heterogeneous environment

Various information systems in the heterogeneous environment have resulted in a lot of discrete business data, and this type of storing method decreased the sharing of the data. In this paper, we designed and implement a secure data transmission scheme in the context of High Education Examination Management Information System of Shandong Province (HEEMISSP), in which all kinds of factors in the heterogeneous environment is taken into consideration. We integrate the security certificate technology and the encryption method with the remote method invocation (RMI). Measured by the security, completeness and non-repudiation of data transmission, the design fully satisfied the efficiency of data transmission which is requested by customer.
