Abstract
Official abstract text for this publication.
A process and system for enciphering and deciphering Unicode characters that is compatible with scripting languages such as JAVASCRIPT®, JSCRIPT® and VBSCRIPT®. The process and system can encipher each character individually and maintain the size of the character. The enciphered character is deciphered at the application layer at the client to provide endpoint security.
First claim
Opening claim text (preview).
What is claimed is: 1. A method comprising: receiving, by a processing device, a stream of Unicode characters from an input stream; identifying a character range out of a plurality of character ranges for each Unicode character of the stream of Unicode characters; selecting an enciphering operation in view of the identified character range, wherein each of the plurality of character ranges corresponds to a respective enciphering operation; enciphering, by the processing devi…
