Abstract: Computer systems and applications are provided for encrypting data that preserves the ability to process the encrypted data. The method includes receiving data in unencrypted form. The method further includes encrypting the data in accordance with an encryption dictionary generated by arranging the plurality of plaintext symbols in lexicographical order; defining a first subset comprising a first plurality of the lexicographically arranged symbols; defining a second subset comprising a second plurality of the lexicographically arranged symbols; defining a first set with a first plurality of unique random tokens within a first token space for use with the first plurality of symbols; and defining a second set with a second plurality of unique random tokens within a second token space for use with the second plurality of symbols such that the second plurality of unique random tokens is non-linear with respect to the first plurality of unique random tokens.

Abstract: Computer systems and applications are provided for encrypting data in a manner which preserves the ability to process the encrypted data. The method includes arranging a plurality of plaintext symbols in lexicographical order; defining respective first and second subsets of the lexicographically arranged symbols; defining a first and a second set of random tokens for use with the first and second subsets of symbols, respectively; adding a first random constant value to each token in the first set of random tokens; adding a second random constant value to each token in the second set of random tokens; defining the first set of random tokens comprises establishing a first average distance between tokens; and defining the second set of random tokens comprises establishing a second average distance between tokens; wherein the second average distance is different than the first average distance, and the second random constant value is greater than the first random constant value.
