The random parameters insertion encryption methods of LBS application based on RSA algorithms

In order to meet the market demands of real-time location information in the mode of LBS, while satisfy the coordinate information encryption requirements of State Bureau of Surveying and Mapping, this paper proposes the random parameters insertion encryption methods of LBS application based on RSA algorithms, and applied in actual operations. Operating results show that, in pure-online mode that only pre-loaded base map information and supporting online real-time information updates and releases, LBS could obtain rapid information updates and release services with lower computation, fast and efficient encryption.
