Building a Secured XML Real-Time Interactive Data Exchange Architecture

Abstract

TCP and UDP communication protocols are the most widely used transport methods for carrying out XML data messages between different services. XML data security is always a big concern especially when using internet cloud. Common XML encryption techniques encrypt part of private sections of the XML file as an entire block of text and apply these techniques directly on them. Man-in-the-Middle and Cryptanalysts can generate statistical information, tap, sniff, hack, inject and abuse XML data messages. The purpose of this study is to introduce architecture of new approach of exchanging XML data files between different Services in order to minimize the risk of any alteration, data loss, data abuse, data misuse of XML critical business data information during transmission; by implementing a vertical partitioning on XML files. Another aim is to create a virtual environment within internet cloud prior to data transmission in order to utilise the communication method and rise up the transmission performance along with resources utilisation and spreads the partitioned XML file (shredded) through several paths within multi agents that form a multipath virtual network. Virtualisation in cloud network infrastructure to take advantage of its scalability, operational efficiency, and control of data flow are considered in this architecture. A customized UDP Protocol in addition to a pack of modules in RIDX adds a reliable (Lossless) and Multicast data transmission to all nodes in a virtual cloud network. A comparative study has been made to measure the performance of the Real-time Interactive Data Exchange system (RIDX) using RIDX UDP protocol against standard TCP protocol. Starting from 4 nodes up to 10 nodes in the domain, the results showed an enhanced performance using RIDX architecture over the standard TCP protocol.
