Computer program product and method for order preserving symbol based encryption
View Patent ↗A method for processing symbols by a first computerized entity, the method may include receiving, by a first computerized entity and over a communication network, text that comprises multiple random tokens and a plurality of plaintext symbols; wherein the multiple random tokens are generated by a second computerized entity; wherein a value of each random token that represents a plaintext symbol is responsive to values of random tokens that represents plaintext symbols that have a lower lexicographic value than the plaintext symbol; and processing the text by the first computerized entity.
1. A method for processing symbols by a first computerized entity, the method comprising:
receiving, by a first computerized entity and over a communication network, encrypted text that comprises multiple random tokens and a plurality of plaintext symbols;
wherein the multiple random tokens are generated by a second computerized entity;
wherein a value of each random token that represents a plaintext symbol is responsive to values of random tokens that represents plaintext symbols that have a lower lexicographic value than the plaintext symbol; and
processing the encrypted text by the first computerized entity, wherein the processing is selected from a group consisting of sorting and searching.
2. The method according to claim 1 , wherein the first computerized entity supports a software as a service application.
3. The method according to claim 1 , wherein the first computerized entity supports a data base application.
4. A non-transitory computer readable medium that stores instructions for:
receiving, by a first computerized entity and over a communication network, encrypted text that comprises multiple random tokens and a plurality of plaintext symbols;
wherein the multiple random tokens are generated by a second computerized entity;
wherein a value of each random token that represents a plaintext symbol is responsive to values of random tokens that represents plaintext symbols that have a lower lexicographic value than the plaintext symbol; and
processing the encrypted text by the first computerized entity, wherein the processing is selected from a group consisting of sorting and searching.
5. The non-transitory computer readable medium according to claim 4 wherein the first computerized entity supports a software as a service application.
6. The non-transitory computer readable medium according to claim 4 wherein the first computerized entity supports a data base application.
7. A system, comprising a first computerized entity for:
receiving over a communication network, encrypted text that comprises multiple random tokens and a plurality of plaintext symbols;
wherein the multiple random tokens are generated by a second computerized entity;
wherein a value of each random token that represents a plaintext symbol is responsive to values of random tokens that represents plaintext symbols that have a lower lexicographic value than the plaintext symbol; and
processing the encrypted text by the first computerized entity, wherein the processing is selected from a group consisting of sorting and searching.
8. The system according to claim 7 wherein the first computerized entity supports a software as a service application.
9. The system according to claim 7 wherein the first computerized entity supports a data base application.
