METHOD AND A SYSTEM OF ENCRYPTING WEB COMMUNICATION DATA FOR SUPPORTING WEB STANDARD, CAPABLE OF BEING USED IN VARIOUS WEB BROWSERS WITHOUT INSTALLING AN ADDITIONAL THIRD PARTY PROGRAM

摘要

PURPOSE: A method and a system of encrypting web communication data for supporting web standard are provided to encrypt data in various web browsers without installing an additional program.;CONSTITUTION: A web browser asks an input page requiring encryption transaction to a web server. The web server creates encryption instance (102) in a server side using an encryption key (100) to be used in encryption. The web server stores the encryption key in a session object to access the encryption key in a web browser. The web server stores the encryption key to a java script so that the java script can access the encryption key in the web browser when the input page is created. The web browser initializes an encryption module (103) formed of the java script to an encryption key (101) same as the server when the created web page is loaded and parsed.;COPYRIGHT KIPO 2013;[Reference numerals] (101,KK,NN) Obtain an encryption key; (103,102) Generate an instance; (AA) Client; (BB) Data encryption; (CC) Web browser; (DD) User request; (EE) Java script loading; (FF) Data input; (GG,II) Request; (HH) Response; (JJ) Server; (LL) Store the encryption key; (MM) Page Generation; (OO) Data decoding
