The spatial data sharing security model based on hybrid encryption algorithm

Hybrid encryption algorithms are flexible tools for modeling the correlation of random variables. They cover the scope from completely negative correlation to positive correlation, including independent cases and contain asymmetric correlation and broadly employed Gaussian correlation structure. The pair-encryption algorithm of the hybrid encryption algorithm takes advantage of the ease of use of the two-variable encryption algorithm, and it is recommended to decompose the hybrid encryption algorithm into a set of two-variable encryption algorithms. We have successfully applied this method to spatial data and established a powerful interpolation method on basis of spatial logarithm.
