Research on Security of Spatial Information Transmission in Middleware System Based on G/S Mode

With the expansion application of spatial information, the G/S model achieves the new span that the way accessing to spatial information network changed from the current structure of C/S and B/S. The middleware is not only an important part that the G-side communicate to the S side in G/S model, but also particularly important for the spatial data transmission security. On the account of the security in the middleware system. the technology that the secret key is distributed limitedly was proposed to solve the problem of end - to - end encryption. Besides, the technology play an effective guarantee for the efficient use of network in G/S model and middleware system for spatial data security.
