Abstract
Official abstract text for this publication.
A method and system for consistent format preserving encryption (C-FPE) are provided to protect data while the data is in a domain while allowing encrypted data to be treated inside the domain as if it were the unencrypted data. The method includes inserting a coupling into a data flow at a perimeter of the domain, and translating a data element from an unprotected data element to a protected data element using the coupling such that the data element is a protected data element within the domain.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of protecting a data element within a domain, the method comprising: inserting a coupling into a data flow at a perimeter of the domain, wherein the data flow through the coupling into the domain comprises the data element; and translating the data element between an unprotected form and a protected form using the coupling; wherein translating the data element from the unprotected form to the protected form comprises encrypting the data el…
